Getting Started with OrCAD Capture Lesson 1
1-2 OrCAD Capture Version 16.5 May, 2011
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.

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
.
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.

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 pre-selecting it before you perform the task. Menu choices are also affected by project type.

The Footprint Viewer Toolbar
Available in Version 16.5, the Footprint Viewer Toolbar provides a three dimensional view of the Footprint symbol of a selected part on the schematic page or in the Part Editor. This a quick snap shot or view of the Footprint pattern you have assigned to your OrCAD Capture part. Along with the Footprint symbol the viewer also displays pin numbers and pin names and allows you to measure distances between pins.
A Footprint name MUST be assigned to the OrCAD Capture part before you can view the Footprint. The property is PCB Footprint with it’s value being the Footprint name.
In the Part Editor, the part you create MUST match the Footprint pin numbers.
Besides viewing the Footprint, you can also use the 3D measure tool to measure any distance across the Footprint and across the x, y or z axis.
Opening the Footprint Viewer window will display the footprint assigned to the selected part on the schematic page.

“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.
