This walk-through demonstrates how to generate a netlist and new layout file for your Capture 22.1 (2022) schematic. After you complete this topic, you will be able to:
To follow along, continue with the design from the last topic or use the provided design files. If the design files were not downloaded in the beginning of the Capture Walk-Through, the design files for this lesson can be found under the Materials tab.Open in New Window
Note: This creates only a netlist. To create both a PCB Layout and netlist in one step, move ahead to Creating the PCB Layout.
Step 1: Select the capture_tutorial.dsn file in the Project Manager.
Step 2: Select Tools > Create Netlist from the menu. The Create Netlist window opens.
Step 3: Under the PCB tab, check Create PCB Editor Netlist.
Step 4: Under Options, select the ellipsis to browse for a location to save the netlist.
Step 5: The file browser opens. Select the desired folder to save the netlist in and click Select Folder.
Note: Typically, this is a subfolder within the project folder named allegro.
Step 6: If this is your first time netlisting, select Setup.
Step 7: The configuration file needs to be defined. Select the ellipsis.
Step 8: Browse to the location of the allegro.cfg file. The default file path is: C:\Cadence\SPB_22.1\tools\capture.
Step 9: Select the file and click Open. Click OK in the Setup window.
Step 10: Click OK to netlist the design.
Note: The netlist files pstxnet.dat, pstxprt.dat, and pstchip.dat are generated in the specified location.
Step 11: To create a PCB layout, select PCB > New Layout from the menu. The New Layout window opens.
Step 12: Select the ellipses for PCB Layout Folder to open the file browser.
Step 13: Browse for a location for the board file to be saved. Click Select Folder.
Step 14: In the Board field, enter a name for the board file.
Note: By default, this is the same as the project name.
Step 15: Leave Input Board File blank to create a new design.
Step 16: Click OK to create the new layout.
Step 17: The Cadence Allegro Product Choices window will open. Select OrCAD PCB Designer Professional from the list and click OK.
Note: This will open the new PCB layout file, which will be used in the PCB Walk-through.
This concludes the OrCAD Capture Walk-through. Continue learning OrCAD with the PCB Walk-through or PSpice Walk-through.
