Cadence OrCAD Capture & Cadence OrCAD Capture CIS
OrCAD Capture release 16.3 continues to boost productivity through new GUI updates, 3-D footprint viewing, a new auto-wire connection capability, and enhanced scripting with TCL/TK support. Cadence OrCAD Capture CIS release 16.3 provides more control and visibility over the relational data from the CIS database, and contains all the productivity and usability improvements highlighted in OrCAD Capture.

Auto-Wiring: OrCAD Capture 16.3 now includes an auto-wiring feature that allows users to wire two or more pins or wires on a schematic page. With this new functionality, wiring between component pins is as simple as selecting a starting pin and a destination pin and letting the software add the connection - all automatically and quickly.

Design Navigation Improvements: In OrCAD Capture 16.3, users can create intersheet references on flat designs as well as simple or complex hierarchical designs. The design navigation now includes a signal navigation feature to navigate the connected signals on a design. Users can select and highlight the signals from the browse list.

User Interface Enhancements: OrCAD Capture 16.3 users can now change the color, line style, or line width of a wire or net; the color of a block; embed or link an object or image; and place elliptical arcs and multi-point bezier curves on schematic pages.

OrCAD PCB Editor 3-D Footprint Viewer: The OrCAD PCB Editor 3-D Footprint viewer provides a three dimensional view of the footprint symbol of a selected part on the schematic or the part editor. Along with the footprint symbol, the viewer also displays pin numbers and pin names, and can be rotated to view different perspectives. A 3-D measure tool can be used to measure points in x, y, or z axis.

Scripting Support: OrCAD Capture 16.3 includes a TCL/TK scripting functionality that allows users to execute a command through a command prompt. The command can be stored and replayed later. This capability gives users more time to identify the type of script (set of steps) that is required for a specific task.

PCB Flow Enhancements: OrCAD Capture 16.3 now provides a new locking mechanism and warning filter to further enhance users’ PCB flow experience. The Object Locking feature allows users to temporarily lock an object on the schematic or board while cross-probing. The Output Warnings filter provides the option of ignoring numerous electrical constraints during PCB netlist creation.

Electrical Rules: The DRC check in OrCAD Capture 16.3 is now separated out between physical rules and electrical rules. This allows users to choose to run design checks from the available physical and/or electrical rules.

Check and Save: The new Check and Save option (available through the project manager file menu) allows users to run a DRC on the currently checked rules in the DRC dialog.

Power Pin Enhancements: OrCAD Capture 16.3 now includes a new Assign Power Pins command that allows users to select the power pins on the design they want to route and then set all the other power pins as NC pins.

Bill of Materials: With OrCAD Capture CIS 16.3, users can now include relational fields in their Bill of Materials if there are defined relational fields in their CIS configuration.

Relational Data Report: When users include relational data in their reports, they can also choose the display format for this data. Relational data can be displayed horizontally (in the same row) or vertically (one line item per related data). The maximum number of related child items to output can also be specified.

Variant Not Stuffed: Users can use the new Variant Not Stuffed Qty 0 option if they want their reports to include any variant parts that are not present. These parts will be displayed in the report with zero quantity.

Cadence PSpice A/D
PSpice A/D release 16.3 provides users with a complete makeover of its waveform environment, along with new usability improvements, enhanced cursor support, and new simulation models. Cadence PSpice Advanced Analysis contains all the productivity and usability improvements highlighted in PSpice A/D.

Easy To Use Pop-Up Menu for Traces: The context-sensitive menu for traces is now more usable with all the trace related options grouped together. When users select a trace and right-click, they are presented with the options in context of the trace.

Easier Access to Trace Properties: Users can now choose Trace Property in the trace pop-up menu to open the Trace Properties dialog box. This dialog box gives a range of choices to change color, pattern, width, and symbol for a selected trace, making it easier to identify individual traces. This dialog box also allows users to easily hide all traces or show all traces.

Controlling Background and Foreground Colors: Users can now specify different colors for the background of the Probe window, as well as grids and axis lines in the foreground.

Customizing Auto-Rotation of Trace Color: PSpice A/D 16.3 users can choose to change the default trace colors from an extended list of 145 supported colors.

Setting Cursor Width and Color: The Cursor Settings tab of the Probe Settings dialog box allows users to specify the vertical and horizontal width and color for two cursors. The number of cursor digits can also be specified.

Placing Cursors Across Multiple Traces and Plots: PSpice A/D 16.3 users can add cursors across multiple traces and plots. The cursor window displays values for the different traces.

Exporting and Copying Cursor Data: PSpice A/D 16.3 users can export the cursor information to a comma separated value (.csv) file that can then be opened in various tools, such as Microsoft Excel. Users can also copy selected values from the cursor window and paste the information from the clipboard to any text editor.

Dockable Cursor Window: In PSpice A/D 16.3, the Cursor window is now dockable and can be placed anywhere the user finds convenient.

Exporting Comma Separated (CSV) Files: Users can now easily export trace information as .csv files by choosing File Export Comma Separated in the PSpice A/D Probe window. The trace information for specified variables will be exported to a location and file as specified by the user and can be read using various tools, such as Microsoft Excel.

Faster .dat File Import and Export: In previous releases, the performance of large .dat files 2GB or more in size was improved. In the 16.3 release, the performance when opening a .dat file has been enhanced for files of all sizes.

Highlighting In Circuit And .out Files: In PSpice A/D 16.3, circuit and .out file syntax are presented in easy to read colors that highlight the different groups, such as text, numbers, comments, expressions, operators, and keyword. Users can also specify their own color schemes for the files.
