2 Getting Started with OrCAD Capture Lesson 1 The OrCAD Capture tool provides support for programmable logic design. OrCAD Capture is tightly integrated with the OrCAD and Allegro PCB Editor design, SPECCTRAQuest for high-speed circuit analysis, and Advanced Package Designer for multi-chip and single-chip modules. OrCAD Capture supports digital simulation using Verilog or VHDL models, or analog simulation with PSpice A/D. OrCAD Capture also uses a Cadence OrCAD Component Information System (Cadence OrCAD Capture CIS) to integrate your board-level design with existing in-house part procurement and manufacturing databases. The procedures included within this training guide can be used with both the standard OrCAD Capture application and OrCAD Capture CIS. More Information OrCAD Capture supports programmable logic design by accessing synthesis and simulation tools, and by providing libraries for the most popular FPGA/CPLD vendors. Increased integration provides easy access to NC VHDL Desktop for simulation. Further, OrCAD Capture includes functionality for generating simulation test benches and provides numerous coding samples that you can use when developing your designs and test benches. If you have installed Synplify on your system, you can launch it from within the OrCAD Capture user interface, create a Synplify project, and invoke the tool on your programmable logic design.orcad Capture also launches the place-and-route tool set appropriate for the target vendor (provided that the tool set is installed on your computer). OrCAD Capture includes Verilog and VHDL editors with keyword highlighting and syntax checking. It lets you create hierarchical blocks from Verilog and VHDL entities, and vice versa. OrCAD Capture also includes functionality that lets you simulate multiple programmable logic devices in a manner that represents the interaction of devices on a printed circuit board. You can use either VHDL or Verilog as the hardware development language to represent the devices. 1-2 OrCAD Capture Version 16.5 May, 2011

9 Lesson 1 Getting Started with OrCAD Capture The Project Manager The Project Manager is a window that displays a directory tree of all files related to your design or project. Project Type Project Name Design Name Design File Schematic Folder Schematic Pages Reports Bills of Materials Netlists Embedded Library The project name and project type are shown at the top of the Project Manager window. (Project types will be covered in Lesson 8.) You can use the Project Manager to open schematic pages and view reports, schematic pages, or other project files which open when you double click a page or file name. You can also use the Project Manager with the right mouse pop-up menu to add, delete, or rename schematic pages. You can open multiple projects at the same time, and copy designs or schematic pages between Project Manager windows. You can also use the Project Manager to add libraries to your project setup. When you open a project, the setting preferences last used before the project become active in the open project. For example, if a schematic page was open when you saved and exited the project, that schematic page will automatically display when you reopen the project. May, 2011 OrCAD Capture Version

10 Getting Started with OrCAD Capture Lesson 1 A Simulation Resources folder (not shown in the previous graphic) may also be present for use with PSpice A/D. The OrCAD Capture User Interface OrCAD Capture is a menu driven application. There is no command line entry. All OrCAD Capture commands are contained in pull-down menus, icon toolbars, right mouse pop-up menus, and keyboard shortcuts (or Hot- Keys). OrCAD Capture commands are context sensitive. Access to commands vary with different active windows such as the Project Manager or schematic page. When either window is selected, buttons and menu commands not relevant to the active window are greyed out or missing. Tasks you perform must always be relevant to the current or active window. You can apply a process to a specific page of a design by preselecting it before you perform the task. Menu choices are also affected by project type OrCAD Capture Version 16.5 May, 2011

24 Getting Started with OrCAD Capture Lesson 1 Fish-Eye View The Fisheye feature in OrCAD Capture allows you work on a schematic in a non-linear mode. The two basic features include the Fisheye focus and the Dynamic Fisheye View mode. Fisheye focus Fisheye focus allows you to set focus to specific objects on your schematic.setting the Fisheye focus to one or more objects on the schematic ensures that these objects display in a magnified view. As this happens, the other visible objects are not moved off the page but demagnified. This ensures that you still have a view of the page, but with selected focus. Dynamic Fisheye view In the Dynamic Fisheye view, as the mouse hovers over an object it is immediately magnified. This functions the same as the Fisheye focus mode but in a completely dynamic manner. Also, you can work in both modes simultaneously. Setting focus to one or more objects and then switching on the dynamic mode to pan across the rest of the page. Miscellaneous The Fisheye mode is page specific and not design specific. Also, moving in and out of the Fisheye mode will retain the state of the previous mode. You can use all the zoom operations in addition to the focus feature of the Fisheye. All OrCAD Capture features are available while in this mode. The OrCAD Capture find functionality can be used in conjunction with the Fisheye feature. Finding an object on the page will set the focus to the object. If you press Shift + F11 (shortcut) will immediately set the Fisheye focus for the selected object. Eye Magnification (Fisheye Zoom) In the Fisheye mode, you can set a Fisheye (non-linear) zoom (that is independent of the standard linear zoom). This feature is used in conjunction with the Set Fisheye focus and the Dynamic Fisheye View modes to further zoom into or zoom out of the schematic in a non-linear manner OrCAD Capture Version 16.5 May, 2011

25 Lesson 1 Getting Started with OrCAD Capture Lab 1-2: Using the Fish-Eye View (Optional) Lab Objectives Using the Fish-Eye Mode After you complete this lab you will be able to: Change to Fish-Eye view Set the Fish-Eye focus Dynamically pan with the Fish-Eye view You can use the Fisheye mode to zoom into only specific objects on your schematic. In the Dynamic Fisheye mode, the schematic will zoom into focus areas as the mouse pointer moves over the page. Fisheye view To use the Fisheye features of OrCAD Capture, you need to switch into the Fisheye mode. 1. To switch to the Fisheye mode, right-click on the page. 2. Choose the Fisheye view menu item. Fisheye focus You can set the Fisheye focus to selected objects on your schematic, causing only these objects to zoom while the rest of the viewable area remain in view but is zoomed out.

Note To remove the Fisheye focus, right-click on the page and choose the RsSet Fisheye Focus menu item. (Shortcut Keyboard: Ctrl + Shift + F11 ) Fisheye Dynamic Focus Mode In the Dynamic Fisheye focus, the focus of the page shifts as you move the mouse pointer across the page. As the mouse pointer hovers over a part of the page, only that part of the page comes into focus. The focus area is magnified while the rest of the viewable area loses relative magnification. 1. To Set the Fisheye Dynamic focus mode, right-click on the page. 2. Choose the Fisheye Dynamic Focus Mode menu item. (Shortcut Keyboard: Q ) 3. Now simply move your mouse around the page to pan from area to area. Non-Linear Zoom While in the Dynamic Fisheye mode, you can further zoom into or zoom out of the view to get higher or lower zoom factor as you pan across the page. The magnification factor ranges from a minimum of 2 to a maximum of 10. Remember, this is set in the Preference - Pan and Zoom tab of the Options menu. May, 2011 OrCAD Capture Version
