2 COMMUTER LICENSES 1. Commuter Licensing Introduction Commuter licenses are a type of network license, with the feature that they can be obtained (checked out) from the license server and used while your computer is no longer connected to the network. Commuter licenses are well suited for checking out onto a laptop for travel or for checking out onto any machine that needs to be disconnected from the network but still needs to run Tanner Tools. Commuter licenses for L-Edit, DRC, Extract, LVS, SPR, and Dev-Gen may be obtained while running L-Edit. Commuter licenses for T-Spice and W-Edit may be obtained while running T-Spice, and commuter licenses for S-Edit are obtained while running S-Edit. Commuter licenses may be checkout out for up to fifteen days at a time. In order to check out a license, your computer has to be connected via network to the license server, and has to have a valid license from that server for the product you are trying to checkout. revised 01/06 2

3 1.1. Obtain Commuter Licenses To check out licenses select Help > Commuter Licenses > Obtain Commuter Licenses. This command opens a dialog box that lets you choose the features of L-Edit you wish to obtain commuter licenses for. Check the box for each feature you wish. Not all features may be available as commuter licenses. You also select the expiration date, up to 15 days in the future. The licenses expire at midnight on the expiration date selected. Allowable dates are shown in bold in the calendar control Extending a license or adding to an existing license If your PC already has a commuter license for any of the features being requested, it is returned just prior to processing the new request. This enables one to add commuter licenses to existing commuter licenses. For example you can obtain a 15-day commuter license for just L-Edit, and 3 days later you can obtain commuter licenses for L-Edit and DRC for 15 days from that date. If you already have revised 01/06 3

4 commuter licenses checked out, the expiration date can be extended by simply obtaining the licenses again and selecting a later expiration date Using the TANNERHOST environment variable The commuter license is first searched for on the server from which the current license is obtained, if it is a network server. If a commuter license is not obtained from that server, then the servers listed in TANNERHOST variables are tried. A local broadcast for a commuter license server is not done. In any one operation, once we get a commuter license from a server, we only look to that server for the rest of the requested commuter licenses. By using the TANNERHOST environment variable one can run the L-Edit main program from a hardware lock, and obtain commuter licenses for DRC Extract and LVS from a network server. See Section 3. Network licensing: Client for further discussion of the TANNERHOST variable Return Commuter Licenses To return licenses select Help > Commuter Licenses > Return Commuter Licenses. This command returns all commuter licenses after confirming that you wish to return them. Returning commuter licenses from L-Edit, for example, will return the L-Edit Pro commuter licenses as well as T-Spice Pro and S-Edit licenses. You are not required to return commuter licenses. If you do not return commuter licenses, they will automatically expire and become available again as normal licenses from the server on the expiration date selected when the licenses were checked out. revised 01/06 4

5 1.3. Commuter License Status You can check the status of commuter licenses by selecting Help > Commuter Licenses > Commuter License Status. This command opens a dialog box that displays the commuter license status. Initially, the dialog shows each feature that is currently checked out or is available for checkout. Pressing Show Details displays additional information. revised 01/06 5

6 For each separately-licensed feature, a row appears in the table, whether or not licenses for that feature are available. A separate row for base license and version license can appear if the feature is commutable or have been commuted to your PC. For commuted licenses, the server column identifies the server the licenses were obtained from, and the expires column shows the expiration date. For licenses available to be commuted, the server column says commutable. Each feature has a small graphic next to it, so you can tell its status at a glance. The graphics are: No license for this feature is installed on the license server from which you got your current license to run L-Edit. You currently have a commuter license for this feature. This feature can be checked out, but is not currently available. This feature can be checked out, and is currently available Commuter Licensing Requirements In order for commuter licensing to work properly you must meet the following requirements: You must have commutable network licenses on your license server. You must be running Version 7.2 of the SentinalLM license server. You must have Administrator privileges on your machine or have write access to the system folder and registry in order to be able to check out commuter licenses. revised 01/06 6

7 LICENSING SETUP FOR TANNER SOFTWARE PRODUCTS All Tanner software products use built-in systems to facilitate license management. These systems are designed to provide flexibility in using Tanner products, while regulating when, where, and how the products can operate in accordance with the legal license. To provide maximum flexibility for system administrators and to accommodate different network configurations, Tanner provides two kinds of licensing mechanisms: local and network. When you purchase licenses for Tanner products, you can choose between these mechanisms or combine them. Local licensing links the software to a piece of hardware in the user s computer. Usually the associated hardware is a small device called a hardware lock, which is provided with the software. The hardware lock attaches to the computer s parallel or USB port and serves as a signature for the software to verify licensing. No network connection is needed for the local model; to use the software on a different computer, (at home, for example), just take the hardware lock with you. Network licensing is based on the client-server model. In this model, one or more computers on a company network are set up as license servers, and users can run our software on client computers. Through a network connection, client computers can request and acquire licenses from the license server(s) as needed. This model is more flexible than local licensing, but it requires a permanent network connection and a reliable DNS server to start and operate the software. Network traffic generated by licensing is very small, allowing this method to easily work over very slow networks. This document includes instructions for setting up local and network licensing, which require very different installation procedures. Please read the appropriate section for your licensing model. Note: If you are installing T-Spice Pro with the ViewDraw option, please read Section 4 in addition to other applicable instructions; ViewDraw licensing differs from other Tanner products in several important ways. 2. Local licensing Setup of local licensing requires the following items, provided by Tanner: Hardware lock. This is a small device that attaches to either the parallel port or USB port on your computer. Tanner License Update file (.TLU extension). This file should have been sent to you as an attachment. Note: If you do not have these items and you want to use local licensing, please call Tanner technical support to make arrangements. Once you have a hardware lock and.tlu file, continue with the following steps: 1. Make sure you have finished installing your new Tanner software on your computer. By default, software installation includes the utilities that will assist you in setting up licensing. 2. If you have a hardware lock that attaches to the parallel port, turn your computer off, attach the lock, and then turn computer back on. If you have a USB lock, you can attach the lock while your computer is running. 3. Navigate to your.tlu file. Double-click on the filename to start the Tanner License Installer utility. 4. In the Tanner License Installer window, click Install. revised 01/06 7

Click Exit to close the License Installer, then restart your computer if required. Note: More information about your license is available in the SentinelLM User s Guide. You can access this document from the Start Menu by selecting Start > Programs > Tanner EDA > Utilities > Documentation > SentinelLM Guide. Please be aware, however, that this document is provided by Rainbow Technologies, Inc. (the distributor of SentinelLM) and not all information is applicable to Tanner products. 3. Network licensing: Client In simple fast networks, client computers do not require any set up to use network licensing. Simply install the Tanner software and run it; the built-in licensing tool will search the network for the license server. When the licensing tool finds a server, it will lock to the server location and acquire licenses. Tanner software requires license updates from the server approximately every three minutes. On more complex networks or to speed up operation on a simple network, it is recommended that you set the location of the license server in a Windows environment variable called TANNERHOST. To use this variable, set the value of TANNERHOST to the IP address of the network license server. If you do not know the IP address, you can also set this value to the name of the server; however, this method leads to slower operation. If you do not know how to set up environment variables, please ask your system administrator or refer to Section 5 of this document for more information. 4. Network licensing: Server The network license server is generally set up by the System Administrator. Setup requires installation of the license server, a small program that runs on the server computer. You can run the license server as a Windows NT or 2000 service, or as a small resident program on Windows 98 or Me machines. (Tanner products no longer support Windows 95.) Windows 2000 is the recommended platform for running the license server. Setting up a network license server requires the following items, provided by Tanner: Hardware lock. This is a small device that attaches to either the parallel port or USB port on your computer. Tanner License Update file (.TLU extension). This file is usually sent to you as an attachment or on a diskette included with the product(s). Note: If you do not have these items and you want to use network licensing, please call Tanner technical support to make arrangements. Once you have a hardware lock and.tlu file, continue with the following steps: 1. To begin installation, go to the LICSERV folder on your CD and run setup.exe. This will install the Rainbow SentinelLM License Manager, the Sentinel driver for parallel and USB ports, and the Tanner licensing utilities. You do not need to install Tanner software products to set up a license server. 2. If you have a hardware lock that attaches to the parallel port, turn your computer off, attach the lock, and then turn the computer back on. If you have a USB lock, you can attach the hardware lock while your computer is running. 3. Navigate to your.tlu file. Double-click on the filename to start the Tanner License Installer utility. 4. In the Tanner License Installer window, click Install. 5. If the License Installer prompts you to do so, you must restart your computer for the new license to take effect. Click Exit to close the License Installer, then restart your computer if required. revised 01/06 8

9 Note: More information about the license server program is available in the SentinelLM User s Guide. You can access this document from the Start Menu by selecting Start > Programs > Tanner EDA > Utilities> Documentation > SentinelLM Guide. Please be aware, however, that this document is provided by Rainbow Technologies, Inc. (the distributor of SentinelLM) and not all information is applicable to Tanner products. 5. ViewDraw licensing 1. ViewDraw local licensing is similar to other Tanner products; however, ViewDraw requires a separate hardware lock. If you install the T-Spice Pro Designer package and plan to use ViewDraw, you must connect two hardware locks to your computer. If only one port is available, connect the ViewDraw and Tanner locks in series, placing the ViewDraw lock on your computer first. 2. ViewDraw network licensing uses the same client-server model as other Tanner products, but ViewDraw uses the FlexLM license manager. All other Tanner products use the Rainbow SentinelLM license manager for network licensing. Please read the install.wri file on your T-Spice Pro Designer CD for instructions on installing the FlexLM server and configuring client computers. Note: More information about ViewDraw network licensing is available in the FlexLM User s Guide. If you have installed T-Spice Pro Designer with ViewDraw, you can access this document from the Start Menu by selecting Start > Programs > Tanner EDA > Utilities > Documentation > FlexLM Guide. Please be aware, however, that not all information is applicable to Tanner products. 6. Licensing Environment Utility The Tanner Licensing Environment utility helps you to easily setup the required environment variables required for obtaining licenses. You can use this utility, or you can set environment variables manually, as described in the next section. revised 01/06 9

10 You can access this utility by clicking Start > Programs > Tanner EDA > Utilities > Licensing Environment. 7. Setting environment variables Licensing setup frequently requires setting one or more Windows environment variables. It is recommended that variables be set by the system administrator when possible. Instructions for setting environment variables depend on the version of Windows you are running. Please refer to the appropriate section for information applicable to your current version Windows In the Desktop, right-click on the My Computer icon. 2. Select Properties from the menu. 3. In the Properties dialog, select the Advanced tab. Click Environment Variables 4. Press Alt+W to open the New System Variable dialog box. Note: If you are setting up a license server, you must set System variables. If you setting up a licensing client, you may set either User or System variables. 5. Type the variable name and value and click OK. 6. Repeat steps 4 and 5 as needed to set up more variables, then click OK to close the dialog. 7. For changes to take effect, you must restart any Tanner programs that were running when you modified the environment variables. If changes were made to a license server, you must restart the server computer. revised 01/06 10

11 7.2. Windows XP 1. In the Desktop, right-click on the My Computer icon. 2. Select Properties from the menu. 3. In the Properties dialog, select the Advanced tab. Click Environment Variables 4. Under System Variables, click New to open the New System Variable dialog box. Note: If you are setting up a license server, you must set System variables. If you setting up a licensing client, you may set either User or System variables. 5. Type the variable name and value and click OK. 6. Repeat steps 4 and 5 as needed to set up more variables, then click OK to close the dialog. 7. For changes to take effect, you must restart any Tanner programs that were running when you modified the environment variables. If changes were made to a license server, you must restart the server computer. 8. Tanner License Installer Tanner License Installer is a utility that aids in installing new or updated licenses for Tanner products. Licenses are distributed as Tanner License Update files (extension.tlu) with each product release. Tanner License Installer can be invoked by double-clicking on any TLU file or from the Windows Start Menu using Start > Programs > Tanner EDA > Utilities > License Installer. Simply follow the prompts to install your license. 9. Tanner Computer ID utility Most licenses for Tanner tools are linked to a mobile hardware lock, which can be attached to one computer and then moved to another, as needed. In rare cases in which use of mobile hardware lock is not acceptable, Tanner licenses may, for an additional fee, be configured to lock to other unique features of your computer. Your computer's unique ID can serve as an alternative to the mobile hardware lock; however, this licensing scheme has the disadvantage you cannot move licensed products from computer to computer. The Tanner Computer ID utility detects your computer s ID for licensing without a hardware lock. You can also use this utility to IDs to Tanner technical support, or to save them to file for later use (for example, to be printed and faxed to Tanner). You can invoke the Tanner Computer ID utility from the Windows Start Menu by clicking Start > Programs > Tanner EDA > Utilities > Computer ID Utility. 10. Frequently Asked Questions 9.1 Can I connect other devices, like a printer or Zip drive, to the hardware lock that attaches to the parallel port? Because parallel ports (unlike USB ports) are not designed for such kind of sharing, we do not recommend attaching other devices. Never connect a scanner or zip drive to a hardware lock on your parallel port, either C-Plus-B or Super-Pro. Zip drives and most scanners will destroy your hardware lock. Instead, you should consider installing a second parallel port or requesting a USB hardware lock from Tanner technical support. Note that USB locks will not work with Windows NT Can I connect several hardware locks to the same computer? revised 01/06 11

12 You can connect a Tanner primary lock and ViewDraw lock to the same port. In this case, you should place the ViewDraw hardware lock on the computer first, then attach the Tanner primary lock. You can also connect a Tanner lock with a lock from any other company. You usually cannot connect two Tanner locks to the same computer, because only one of the locks will be recognized by our software. 9.3 Can I switch hardware locks without first turning off my computer? You should never change locks that attach to the parallel port while your computer is on; doing so may severely damage the locks. USB locks can be swapped at any time. 9.4 What network protocol does SentinelLM licensing server use? It uses UDP protocol (for TCP/IP). 9.5 Which TCP/IP port does SentinelLM licensing server use for communication? By default, it uses port You can change it by setting an environment variable on a server (and rebooting the license server computer for changes to take effect): SET LSERVOPTS=-port portnumber. On the client, you must put the port number after IP address of the server (or host name) separated by a colon. SET TANNERHOST=server-ip-address:port-number. Example 1 (server): SET LSERVOPTS=-port 5555 Example 2 (client): SET TANNERHOST= : Can I install multiple SentinelLM servers? You can have more than one license server. You should configure each server the same way that you configure a single server. Divide licenses between servers in the most convenient and efficient way, then point client machines to more than one server. There are three additional environment variables reserved for specifying multiple servers; these are TANNERHOST2, TANNERHOST3, and TANNERHOST4. These variables specify the server locations in the order in which they will be scanned for licenses. The software first looks for a license at the server indicated by TANNERHOST, then TANNERHOST2, then TANNERHOST3, etc. If a license is not found on any of these servers, the software looks elsewhere on the network via TCP/IP broadcast. (Note that there is no TANNERHOST1 variable.) 9.7 Can I avoid using an extra computer as the license server? You do not need to dedicate an extra computer to network licensing. You can set up the network license server on your existing server, or you can run the license server on one of the client computers that is also running Tanner tools. In this case, a single computer simply functions as the licensing server and one of the client machines at the same time. 9.8 Can I prevent a client from broadcasting to discover a server? If a server is not found at any addresses pointed to by all TANNERHOST environment variables, the client will broadcast on the local subnet to discover a server. This process can be time-consuming. To prevent the client from broadcasting, set at least one of the TANNERHOST environment variables to local. Example 1 (only look for local license): SET TANNERHOST=local Example 2 (look for license on two servers and don t do broadcast if not found): SET TANNERHOST= revised 01/06 12

13 SET TANNERHOST2= SET TANNERHOST3=local 9.9 Can I include the check for a local license into the sequence of servers? You can check for a local license by using the name no-net instead of a server name. Example: SET TANNERHOST= SET TANNERHOST2=no-net SET TANNERHOST3= Why doesn t the LSFORCEHOST or LSPORT environment variable work? The LSFORCEHOST and LSPORT environment variables described in the Rainbow manuals for SentinelLM are not supported by Tanner products. Please use the TANNERHOST environment variable instead What is the LSERVRC environment variable? LSERVRC is a variable that is set automatically by the Tanner License Installer. This variable points to a license file, which is a text file that is typically also named lservrc. The LSERVRC environment variable is only applicable to locally licensed computers or to network license servers. This variable has no effect on client computers using network licensing What is the Sentinel (Rainbow) driver? This driver is needed for our licensing software to access the hardware lock. This driver is only needed on computers with local licensing and on network license servers. The driver is automatically installed with Tanner software products if needed How is the Tanner license file structured? A Tanner license file is a text file in which each line represents a single license. Each protected feature of our products requires two licenses: base license and version license. The base license (or license of version 0) is required to run any version of that feature. A version license is needed to run each specific version. This is why the full Tanner Tools suite often requires around twenty licenses to run with all features enabled What is the difference between additive and exclusive licenses? We usually issue additive licenses for local licensing and exclusive ones for network licensing. If several additive licenses for the same feature and version are put in the license file, they all remain active. With exclusive licenses only the last license in the file for this feature and version is effective, and the rest are disabled I installed the wrong.tlu file by mistake. Can I roll back the changes? The Tanner License Installer backs up the license file before installing each TLU file. The name of the back up file is reported by the License Installer when TLU file is installed. Usually files are backed up in the subdirectory named lservrc.bak of the folder in which your license file is located. (The environment variable LSERVRC points to the location of the lservrc file. The license file lservrc is usually located in C:\WINDOWS or C:\WINNT.) To reverse the.tlu file updates, simply copy the backup file over your lservrc file. The command to restore the license file will be similar to the following: COPY C:\WINDOWS\lservrc.bak\lservrc.003 C:\WINDOWS\lservrc revised 01/06 13

14 9.16 I deleted the with my TLU file after I installed it. Can I find that TLU file somewhere? After TLU files are installed, they also are backed up in the directory containing the Tanner License Installer. For typical installations, this directory is C:\Tanner\License. If the License Installer is launched from the Start Menu, it automatically searches its home directory for the.tlu file that matches the hardware lock currently attached to the computer. If no file or the wrong file is found, you can click Browse in the License Installer window to locate the correct file What version of Sentinel driver do I need? If you received your hardware lock from Tanner before 2000, you probably have a hardware lock model called C-Plus-B. These locks work with versions 5.30 and higher of the Sentinel drivers. If you have a smaller parallel port hardware lock or a USB port lock, you have the model called SuperPro. SuperPro locks only work with drivers version 5.39 and higher. If you are running Windows 98 or Me and you have Sentinel driver version 5.37 or lower installed, the L-Edit installer will NOT update your driver automatically. In this case, you should uninstall the previous driver and then install a new one from the ldriv.539 folder on your CD Why after my computer goes to "Stand By" mode L-Edit looses license? This only happens if you are using Local Licensing with hardware lock attached to a parallel port. On some computers, when hardware goes into "Stand By" mode, the parallel port is shut down and L- Edit licensing functions cannot continue. If this problem occurs with your computer, disable "Stand By" mode in Windows Control Panel. Alternatively, if your computer has a USB port, you can return your parallel hardware lock and request a USB hardware lock from us L-Edit takes a long time to obtain a license when anti-virus software running. How can I reduce the time? If L-Edit takes a long time to obtain the license when running an anti-virus program, then for Norton Antivirus 2002 software, disable the Norton AutoProtect feature. For OfficeScan/Trend/Virus Buster - turn off the Real Time Monitor. 11. Technical Support and Feedback Please report problems or suggestions to: Tanner Research, Inc. 825 S.
