3 INTRODUCTION Active-HDL offers a completely integrated design entry and verification environment for HDL, C and C++ designs. The product supports C/C++, SystemC, VHDL, Verilog and SystemVerilog designs, OVA, PSL, SVA assertions as well as mixed SystemC/VHDL/Verilog and EDIF simulation. This Quick Start Guide was created to better acquaint users with the software s installation process, using the on-line help files and the toolbars that are included within the product. NOTES: 1. In order to start working with Active-HDL 8.1, you need to have a valid license file. Users who have a valid maintenance contract will be able to use newer versions of Active-HDL. 2. If you are using the software for evaluation purposes, it does not require a license. It can be immediately used for the 20-day evaluation period. Please see the Licensing Section for more details. The on-line help and tutorials are valuable resources for users at all stages of HDL and C design experience. In the beginning stages of using the tool, the online help will explain the functionality and features of the product. As your familiarity with the product grows, the help files can be used as a source of information on utilizing Active-HDL s advanced features in your designs. SYSTEM REQUIREMENTS Active-HDL requires: A Pentium PC or Higher/Compatible 256 MB Physical Memory (512 MB Recommended) Microsoft Windows NT 4.0 with Service Pack 6, Windows 2000 with Service Pack 3 (recommended) or higher, Windows XP with Service Pack 1 (recommended) or higher, Windows XP Professional x64 Edition, or Windows Server 2003 with Service Pack, Windows Vista. Microsoft Internet Explorer version 4.0 or higher (see notes) Hard disk drive with at least 560MB of free space for minimal installation including only standard VHDL and Verilog libraries (3GB for full installation including the Active-CAD Import feature, SystemC libraries, all available system/vendor libraries, and sample designs) Monitor resolution 1280x1024 (recommended) 3

4 NOTES: The hard disk drive requirements calculated by the installation program are approximate and depend on both your operating system and chosen file system. The amount of available physical memory limits the maximum size of the design that can be simulated in Active-HDL. By default, the Windows operating systems allow allocating up to 2GB of operating memory. The latest improvements made to the entire environment and the simulator in particular allow handling a 3GB flat virtual address space and the simulation of designs that require up to 3GB of memory to run. The following Microsoft Windows operating systems provide applications with a 3GB flat virtual address space: - Windows XP Professional x64 Edition, - Windows XP, - Windows Server 2003, - Windows Server 2003, Enterprise Edition, - Windows Server 2003, Datacenter Edition, - Windows 2000 Advanced Server, - Windows 2000 Datacenter Server, - Windows NT Server 4.0, Enterprise Edition, - Windows Vista. The additional information on how to enable the operating system capability and use the extended memory resources is available on the following Microsoft web page: For full functionality, it is recommended to install the Microsoft Internet Explorer version 5.0 or higher. Active-HDL 8.1 requires the Microsoft Internet Explorer version 4.0 or higher to be installed on your system. If not, the following system components will not be available: Dataflow window Query window in Block Diagram Editor On-line documentation If you have a different Internet browser (other than Internet Explorer) installed on your system, you can continue to use it without any problems. Internet Explorer can be installed as a nondefault browser and be used only by Active-HDL. If you want to install Active-HDL 8.1 on Windows NT with Service Pack 6, Internet Explorer ver. 4.0 or higher is required. Otherwise, Active-HDL will not be installed. 4

5 INSTALLATION When you receive your copy of Active-HDL, insert the DVD-ROM into your machine s DVD-ROM drive. Active-HDL is equipped with an Auto-Run feature that will start the set-up process without having to locate the setup.exe file. At this point you have the option to read the release notes on the product or begin the installation process. 5

6 After reading the release notes or selecting the Next button, you will be asked to read the software s licensing agreement. Read this section carefully and when finished, choose the Accept button. Note: The release notes may be accessed at any time once the software is installed by opening the on-line documentation. Next, you will need to fill in the user information for the software and choose whether or not anyone else will be allowed to access the software from the machine it is installed on. Select Next to continue. 6

7 The installation program of Active-HDL allows you to select components that will be copied or set up during the installation. You can also choose whether to install both VHDL, Verilog, or mixed VHDL-Verilog libraries. The selection results in the installation of different system and vendor libraries that are copied during the installation. The optional components and libraries can be selected in the Active-HDL Setup Program - Setup Type dialog box shown below: This dialog provides the following options: Active-CAD Import Enabling this option, you can install Active-CAD executables and auxiliary files necessary to import Active-CAD designs to Active-HDL environment. Active-CAD files are copied to the \Active subfolder of the Active-HDL installation directory. If this feature is not selected, the subfolder is not created during the installation. SystemC Libraries If this check box is selected, the installation program will install SystemC Class Library files. The files are copied to the \SystemC subfolder of the Active-HDL installation directory. If this feature is not selected, the subfolder is not created during the installation. Run Simulink Interface Setup (required MATLAB installation) This option allows automatic installation and setup of the Active-HDL Co-simulation Interface to Simulink directly in the MATLAB environment. (The interface is required to start Active-HDLSimulink co-simulation. Prior to running the Active-HDL installation, the MATLAB software must be installed first.) The configuration process of the co-simulation interface is started during the Active-HDL installation. In the Simulink Interface Setup dialog box, you will be asked to enter the path to the $matlabroot/bin/win32/matlab.exe file. Clicking on the Next button adds the Active-HDL Blockset block to the Simulink Library Browser and installs the on-line documentation in MATLAB help 7

8 system. If this option is disabled, you will still be able to setup the interface in MATLAB after the process of the Active-HDL installation is finished. The interface files are stored in the \Simulink subfolder of the Active-HDL installation directory regardless of whether the Run Simulink Interface Setup (required MATLAB installation) option is checked or not during the Active-HDL installation. Vendor HDL Libraries Checking this option enables the selection of the type of stimulation libraries. The following options are available: MIX This option allows installing a dual-language set of simulation libraries. VERILOG If this option is selected, only Verilog simulation/schematic libraries will be installed. VHDL If this option is selected, only VHDL simulation/schematic libraries will be installed. Regardless of the selected set of simulation libraries, the functionality and supported features depend ultimately on the purchased license only. Active-HDL 8.1 delivers the updated on-line documentation that is not limited and it provides the help system for all features. MANUAL INSTALLATION OF VENDOR LIBRARIES The installation program of Active-HDL provides additional programs that allow users to (re)install individual vendor-specific libraries after the installation of Active-HDL. The libraries are stored in the \Verilog and \VHDL subfolders (\Install). The \Sch subfolder contains the installation program of the Xilinx Schematic Libraries. To install a library, start the setup.exe program in an appropriate language and vendor subfolder and follow on-screen instructions. In the next stage of the installation process, you will need to choose which pre-installed IC vendor libraries you will require for your designs. All libraries are based on the latest files provided to Aldec at the time the software was produced. Please check with the appropriate IC vendor for the latest library resources. 8

9 NOTE: If you chose to install Xilinx schematic libraries, there will be a subsequent screen prompting you to select which library you wish to install. DESTINATION LOCATIONS 9

10 After you designate the necessary libraries and click the Next button, you should choose the destination path for the Active-HDL software to be installed on your machine. By default, Active-HDL already has a path selected and will create the required folders on your system s C drive. If you wish to select a new destination, choose the Browse button and locate space for both the software s program files as well as any projects you will create with Active-HDL. LICENSE ENVIRONMENT The next step is to specify the license environment for Active-HDL. During the installation procedure of Active-HDL 8.1, you can select the license environment that will be used to protect the program. The license environment settings should be related to the type of the license you have purchased. The following settings are available in the Choose License Environment window: Evaluation license This option allows you to use Active-HDL 8.1 in the evaluation mode for 20 days without any additional license. The evaluation version features the full functionality of a registered copy with some limitations. You can switch from the evaluation license to the full functional product by applying a license file. The license file will use the Ethernet card number as the license hostid. During the installation procedure, the ALDEC_LICENSE_FILE variable is set. This variable should point to the location of the license.dat file. By default, ALDEC_LICENSE_FILE is set to C:\Program Files\Aldec\Active-HDL 8.1\DAT\license.dat. FLEXid keylock (USB) based license This license method uses the FLEXid keylock attached to the USB port of your computer. Before you choose this type of licensing, make sure if your workstation supports the USB standard and that the USB keylock is disconnected from the USB port of your computer while installing Active-HDL. The 10

11 installation program will automatically copy and install all required drivers in your computer. This type of the license also requires the license file. The license file will use the FLEXid keylock number as the license hostid. The ALDEC_LICENSE_FILE variable is set during the installation and it points to the default location of the license.dat file. This option is unavailable when you are installing Active-HDL on Windows NT 4.0 and requires manual installation (change) of USB keylock drivers (FLEXid=9) after Active-HDL is installed. The installation program that installs files required for Windows NT 4.0 (aksnt4usb.exe) can be found in the \License\Drivers\usb4nt\ subdirectory of the Active-HDL installation DVD. Network floating license This option allows you to start Active-HDL 8.1 that is protected by the network license server manager. The floating license also requires the license file. During the installation of Active-HDL, the ALDEC_LICENSE_FILE variable is set. This variable should point to the location of the license.dat file or the license server. If you specify the license server, you can use either of notation: or FILE ASSOCIATIONS The next step is to select the file types you wish to register to Active-HDL. For each file selected, Active-HDL will be the default program associated when working with these files. By default, each file is checked for use with Active-HDL. Click Next to continue with the installation. 11

12 You may wish to check the information listed in this screen to verify that all paths and associations are correct. If not, you may click the Back button to return to the appropriate stage of the installation setup and make any changes. Choose Install when you are ready to begin copying files to your system. When the installation is complete, you have the option to immediately register your copy with Aldec to ensure you receive the latest updates and product information. Choose Register Now and fill out the simple form or click Finish to conclude the installation process. ON-LINE RESOURCES ACCESS Active-HDL 8.1 enables a new option in the Help menu. The Aldec on the Web option provides links to the Aldec web site that gives users access to the Active-HDL-related on-line resources such as: - Active-HDL Home Page; - On-Line Support Request Page; - Download Active-HDL Updates Page; - Knowledge Base; - Aldec Home Page. The Active-HDL check for updates option has been implemented. The option allows ActiveHDL to automatically check the Aldec web site for available updates. Users can set the check intervals to be done once a month, week, day, or disabled. If checking for updates is enabled, the Download Active-HDL Updates window is displayed when Active-HDL starts. 12

13 The window allows changing the default time interval. If the automatic check is disabled, it can always be run manually by choosing the Download Active-HDL Updates option from the Help Aldec on the Web menu. USING THE ON-LINE DOCUMENTATION As you begin to familiarize yourself with the software, there are some useful resources available to help use the tool effectively. Aldec has developed the in-depth on-line documentation and tutorials for those who are new to HDL design or just new to Active-HDL. Locating the On-line Help From the Help menu on the tool bar of Active-HDL, select the On-line Documentation option. This will open a new window with the complete on-line resources. It is highly recommended that you spend some time exploring the on-line resources, as they can be very valuable tools. 13

18 SAMPLE DESIGNS Active-HDL comes with a series of sample designs that allow users to open a small design and practice using the software on real world applications. Users are encouraged to load a sample design and experiment with all of the tool s features before beginning a new project. These designs can be accessed by clicking File on the main tool bar and selecting Open Workspace/Design Explorer. The Workspace/Design Explorer window will then open and you can select Schematic, Verilog, VHDL, Assertions, Matlab, SystemC, SystemVerilog and mixed language designs. When you select a folder in the left window, all sample designs in that folder will be displayed in the window on the right. Double clicking on the design will automatically open the design files in the design browser. NOTE: It is recommended that you refer to the On-line Help after you have opened a design for Tutorials and Documentation on some of the features of Active-HDL. 18

19 AUTOMATED FPGA DESIGN FLOW MANAGER Active-HDL offers complete design flow integration for all leading EDA vendors with its Tcl-based flow selection. The Design Flow Manager supports designs regardless of vendor tools or type of chip. This independence is of most benefit to system designers because third party EDA tools can all be invoked from a single location and designers can have one common tool to use in all designs. NOTE: If you are seeking an alternate vendor flow or an updated version, check the Aldec website at or submit your support request via the Aldec Technical Support web site at 19

20 SETTING UP THE DESIGN FLOW MANAGER The Design Flow Manager supports all industry-leading synthesis and implementation tools. The Design Flow Manager is fully configurable and can be adjusted to all FPGA vendor-supplied synthesis and implementation tools so that users can freely switch between Actel, Altera, Xilinx, Lattice, QuickLogic and other vendor tools. GLOBAL FLOWCHART SETTINGS The configuration of the Design Flow Manager has changed in Active-HDL 8.1. The global settings for the Design Flow Manager are now specified in the Preferences dialog box (Flows category). The flowchart configuration is also enabled while creating a new design in the New Design Wizard. If the Design Flow Manager is disabled in Active-HDL, it is still possible to specify the default target technology and family used e.g. in a design targeted to the Xilinx technology (based on schematic block diagrams). The settings for the active design can be customized in the Design Settings dialog box (General category). DESIGN FLOWCHART SETTINGS Once the Flow Settings feature is invoked, users can specify the synthesis and implementation tools that they will be using for this design. With the Tcl based flows, designers can customize the flows and add additional tools that may be required during the verification process. This adds flexibility to the design process and allows the instant addition of user-approved tools. 20

21 The Design Flow Manager will now invoke specified tools and complete automation of the FPGA design flow is now available. 21

22 SPECIFICS OF THE DESIGN FLOW MANAGER The Design Flow Manager simplifies the network configuration process for IT departments because the end user's machine can be customized to support only those licenses and systems that are available to that specific PC. This licensing customization feature prevents restricted licenses of synthesis and implementation tools to be mistakenly called upon during the design process. The flow was made to provide maximum flexibility for the entire design process. It enables designers to disable certain parts of the design flow so that they can concentrate on the specific areas of the design cycle that they are currently working on. The flow also permits designers to edit the list of tools supported so that only those that a designer uses most frequently will be invoked. PROJECT CONTROL When synthesis and implementation are running in batch mode, the FPGA Design Flow Manager back-annotates the results directly into the Active-HDL environment so that system designers do not have to manually transfer the results. This allows tracking the design progress from one centralized location. Since all files are managed through a single project manager, the users are able to quickly run gate level and timing simulations with the same stimuli files. LICENSING INFORMATION EVALUATION VERSION 20 DAY WITHOUT LICENSE The evaluation version provides full functionality of a registered copy with the following limitations Expires 20 days after installation Export of design and workspace resources to the HTML and PDF format is disabled Printing is disabled The maximum simulation time is 10 us The maximum amount of memory allocated per VHDL, Verilog or mixed VHDL-Verilog design is 5MB. This limitation decreases to 2 MB for any designs employing EDIF-based design units Block diagrams containing more than 15 fubs and/or symbols cannot be saved Apart from Active-HDL, you can also run VSimSA in the 20-days evaluation mode. The evaluation limitations of VSimSA are as follows: The number of processes in the simulated model is limited to 1000 Simulation time is limited to 10us Code Coverage and Design Profiler are disabled 22

23 FULL EVALUATION VERSION 20 DAY ALONG WITH LICENSE If you feel that the evaluation version is too restrictive and you have an Ethernet adapter on your computer, you may apply for a 20-day unlimited license. You can fill out a request form by visiting: or by contacting Aldec or an authorized distributor at: Your 20-day fully functioning license will be sent to you within 24 hours, via , and will expire 20 days from creation, not installation. FULL VERSION In order to continue working with an unlimited version of Active-HDL 8.1, the software requires a license file. Active-HDL can be protected by using either a local or network floating license configuration, which means that the license file can use hostid of your machine or on a remote computer (license server) running on the Windows, Linux, or UNIX platform. LICENSE HOSTID The FLEXnet License hostid can be either the number of the Ethernet card or the FLEXid number of the USB keylock/dongle. LOCAL LICENSE (NODE-LOCKED) The local license (also referred to as a single-user configuration) is tied to a specific machine and requires a license file. In this type of licensing, the hostid form the Ethernet card or connected USB keylock must match the hostid specified in the license file. Keylock drivers are installed on your computer during the installation of Active-HDL. If you need to reinstall the keylock drivers, you can use the setup programs available in the \Drivers subfolder of the Active-HDL installation folder or the \License\Drivers\ subdirectory of the Active-HDL installation DVD. NOTE: You must plug the keylock into the USB port of your computer before you start Active-HDL. NETWORK FLOATING LICENSE The network floating configuration (multiple users) is based on a license started on a remote machine (license server) running on the Windows, Linux or UNIX platform. The floating license also requires the license file. The license contained in the license file can use the hostid of server's Ethernet card number or the FLEXid number of the USB keylock connected to the USB port of the remote computer (except for UNIX machines). Active-HDL supports multiple configurations of the network license. If you have purchased the multiple 23

24 user installation with network licensing that contains several license types, you will be able to switch among them each time you start Active-HDL. If you have purchased a network license with several products enabled in the license file, you can choose your working configuration while starting ActiveHDL in the License Configuration window. Otherwise, when you have the possibility to use only one given configuration, the License Configuration window can be omitted during the Active-HDL start-up. To do so, clear the Show License Configuration dialog box on Active-HDL startup check box in the Diagnose License window. The Diagnose License program is a tool that allows you to check Active-HDL options/features available in your license regardless of the purchased licensing configuration. You can run the tool from the Help menu by selecting the License Information option or by executing the diagnose.exe program in the \Bin subfolder of the Active-HDL installation directory, e.g. if you want to check the available features in the license for VsimSA. If you have purchased a multiple-user installation with network licensing, you will need to: Install Active-HDL on all workstations (also called license clients) Install a license server on your network server (or any other computer permanently connected to the network). Re-configure workstations to use network licensing. All products enabled in your license file can be seen in the last dialog box after you scan your license with Diagnose License. All program files required for setting up a license server are available in the \License directory of the Active-HDL installation DVD. NOTES: Only hardware keylocks attached to the USB port can be used (FLEXid=9). You must plug the keylock into the USB port of your license server before you start the ActiveHDL network license server manager. Active-HDL 8.1 provides an additional program that users can use to setup the license server on the Windows platform. The Aldec FLEXnet License Server (setup.exe) program can be run from the \License\Windows\Aldec_License_Server subfolder of the installation DVD. The \License 24

25 folder also provides files required to run the license server on other platforms. For more information on setting up the Active-HDL license server, refer to the readme_first.txt and setup_license_server.txt files. Active-HDL 8.1 requires FLEXnet ver LICENSE MAINTENANCE In order to start working with Active-HDL, you need to have a valid license file. Starting from ActiveHDL 7.1 SP1 (BUILD 1583.SP1.23, 03/08/2006), only users who have a valid maintenance contract will be able to use newer versions of Active-HDL. Users who have a maintenance contract that expired should install neither updates nor service packs for newer versions of Active-HDL as it will not run with their existing license and report the following error: Your license file does not support this version of Active-HDL. or (FLEXlm error = -5) You do not have valid license to run Acteve-HDL. or (FLEXlm error = -18) License server system does not support this feature. Review the License chapter in the Active-HDL Release Notes to check requirements for software licensing. Contact Aldec for ordering information - sales@aldec.com In order to find out whether your license allows using a newer version of Active-HDL or applying a service pack for a recently released version of the software, check out your current license file. In the header section of the license.dat file, there is a line that determines the Maintenance Expiration Date. If your maintenance has expired you are not eligible to install a newer build or its update (e.g. service pack). The image below presents the example of the license header with the explicitly specified Maintenance Expiration Date. # ALDEC floating license # # Generator build: # License number: # Configuration: AEE-DL(2) # Generated: 3/28/2006 # Expires: 12/31/2008 # Maintenance Expires: 12/31/2008 # You can also find out whether you have a valid maintenance by checking the contents of your license file. It contains a number of lines with a string of information (keyword FEATURE) that define the license features. The license features indicate how long and which version of Active-HDL will run with the license, e.g.: FEATURE ACTIVEHDL_LIC_NUMBER ALDEC dec-2008 uncounted \ The argument (which refers to December 31, 2008) indicates the Maintenance Expiration Date. If your current maintenance contract is valid, you are entitled to the new license with the updated maintenance date. If your maintenance contract has lapsed, you can run versions of Active-HDL released before your maintenance expired or you can renew your maintenance by contacting Aldec at 25

26 MODIFICATION OF PREVIOUS INSTALLS With Active-HDL already installed in your computer you cannot add previously omitted components at any time. To do this you need to run the installation software again. NOTE: User projects are not removed during uninstall and will be visible in the new version of Active-HDL. IMPORTANT NETWORK LICENSING INFORMATION Setting up the license server gives you the benefit of being able to run the software on any platform. This provides design teams the ability to utilize different platforms without having to purchase multiple versions of the same software. Licenses are available anywhere on the network, instead of being tied to specific machines. For more information on setting up the Active-HDL license server, refer to the readme_first.txt and setup_license_server.txt files. HOW TO CONFIGURE LICENSE CLIENTS Active-HDL 8.1 stores its settings in the Windows registry. The default setting for the license file location is the DAT subfolder of your Active-HDL installation (C:\Program Files\Aldec\Active-HDL 8.1\Dat), if you accepted the defaults during the installation. If you change the default location of the LICENSE.DAT file, you need to update the system environment settings. As it is mentioned above, the system variable pointing to the location of the LICENSE.DAT file must be specified to run Active-HDL. The Diagnose.exe application located in the BIN subfolder of the Active-HDL installation may be helpful to verify the current settings. To start the application: Double click its name in Windows Explorer. The Diagnose License window should be displayed. 26

27 Click the Next button: 27

28 The Aldec License Environment Variable fields display the current license environment settings. The path to the license file displayed in the Value field should be the same as the one specified in the system environment settings window (System Properties Advanced (Windows 2000, XP, VISTA) or System Properties Environment (Windows NT)). Click the Next button: This dialog is used to check the validity of the license. If you encounter problems you will see an error message. NOTE: The ALDEC_LICENSE_FILE variable, by default set during the Active-HDL installation, points to the same location that is displayed by the Diagnose License program. To run Active-HDL 8.1 on your workstation you must set a system variable pointing to the location of the LICENSE.DAT file. There are two predefined system variables used for checking licensed features: o ALDEC_LICENSE_FILE o LM_LICENSE_FILE If the first one, considered as the default variable set during the Active-HDL installation, cannot be found in your system, the standard LM_LICENSE_FILE variable is searched for. In case when neither ALDEC_LICENSE_FILE nor the LM_LICENSE_FILE variable is accessible, ActiveHDL starts in the evaluation mode if the evaluation license is not expired. If your LICENSE.DAT file is stored in a different location, the path to it can be specified only by changing the ALDEC_LICENSE_FILE or LM_LICENSE_FILE variables. 28

29 Active-HDL provides a new tool that allows users to check the license. The Diagnose License program (\Bin\diagnose.exe) can be also started after clicking the License Information option in the License Configuration dialog or from the Help menu. CHECKING COMMUNICATION BETWEEN LICENSE CLIENT AND LICENSE SERVER If your Active-HDL network license server is running without problems (no errors reported, all features from the LICENSE.DAT file listed as available in the log file) but Active-HDL reports that you do not have valid license, it is possible that you are experiencing problems with communication between license client and license server. In this case, you should try LMTOOLS diagnostic program, located in the \Bin subfolder of the ActiveHDL installation directory folder. The latest version of LMTOOLS is available at the Macrovision Corporation website: Please follow these steps to diagnose problem: Start lmtools.exe on the machine where Active-HDL cannot start. Select the Configuration using License File button, then click Browse and select the same license.dat file Active-HDL is using. The selected license file path should be displayed in the text box next to the Browse button as it is shown in the figure. 29

30 Click Server Diagnostics tab in the LMTOOLS window, then click Perform Diagnostics. List of all features listed in the license file and available on the license server should be displayed in the LMTOOLS window. If there are any problems with checking out the features, they will be listed in the LMTOOLS window. If diagnostics did not clarify the situation, click the Server Status tab in the LMTOOLS window, then click Perform Status Enquiry. A list of all license servers running on the server specified in the license file will be listed, sorted by the TCP/IP port number. Active-HDL license server should have correct license file path listed and ALDEC vendor daemon status UP. 30

31 NETWORK CLIENT INSTALLATION Active-HDL 8.1 supports network client installation. In the client-server configuration, Active-HDL 8.1 is installed on a network server and network users run the program directly from the server. Each user must have the Active-HDL Network Client installed locally on the computer. The Active-HDL Network Client Setup copies the minimum set of files required locally on the user's computer and remotely registers the files from the server. The performance of Active-HDL clients depends strictly on the network performance as well as the number of clients running at the same time. The Active-HDL copy installed on the server must have a network license for the appropriate number of users. The procedure for installing Active-HDL 8.1 on a network server is the same as installing the full version on a workstation. The only limitation is that the path to the installation folder on the server cannot contain spaces. Once Active-HDL has been installed on a server, client versions can be installed on workstations. THE PROCEDURE OF INSTALLING ACTIVE-HDL 8.1 NETWORK CLIENT IS AS FOLLOWS: 1. Check whether the folder, where the Active-HDL 8.1 Network. Server is installed, is visible and shared (in read-only mode) for all users. 2. Map the directory (a parent directory of the Active-HDL installation folder; by default, the \Aldec directory is set) or the server drive on which Active-HDL has been installed. It is very important that you do not remove or modify this mapping because Active-HDL files residing on the server are registered remotely on each user computer. Any change to the mapped network drive will make the client installation unusable. 3. Using the Windows Explorer, find the \Netsetup folder on the mapped network drive which is a subfolder of the Active-HDL 8.1 installation folder. The \Netsetup folder contains the setup.exe file. Run this file. 4. Follow the Active-HDL 8.1 Network Client Setup Wizard's instructions. NOTES: 1. The user account on which a network client is installed must have administrative privileges. Also, the setup program requires restarting the machine to complete the installation. After the restart, you must log on the same user account from which you have started the installation. 2. The system libraries are stored on the server. The minimum set of executable files required locally for Active-HDL 8.1 to work. Language Assistant templates. 3. If you want to use any sample designs, you must copy them manually from the server onto your workstation. 4. The Active-HDL 8.1 copy installed on the server must have a network license that meets the required number of client users intended to operate simultaneously. 31

32 EXPORT/IMPORT OF ACTIVE-HDL PREFERENCES Active-HDL enables you to export the current preferences to an external file. The preferences stored in such a file may be applied to any copy of Active-HDL that supports the import feature. The export function as well as the import function of preferences is performed by the Active-HDL Preferences Manager. To invoke this tool, execute the prefman.exe file located in the \Bin sub-directory of ActiveHDL installation folder. The tool may run in two modes: the command line mode or the GUI mode. NOTES: The Active-HDL Preferences Manager cannot be used as long as any copy of Active-HDL is running. If the tool detects a copy of Active-HDL running, it displays an error message and shuts itself down. The following settings are treated as user-specific and do not take a part in the export/import process: o User name, address, company name (Tools Preferences Environment) o My Designs folder (Tools Preferences Environment) o Recent files/workspaces settings GUI MODE To run the Active-HDL Preferences Manager in the GUI mode, execute the prefman.exe program without any additional switches (only the v switch is allowed). As a result, the Active-HDL Preferences Manager dialog box will start. The Active-HDL Preferences Manager running in the GUI mode allows you to perform all the operations that are available in the command line mode. 32
