- Select Open from the File menu 2. Browse to your psmpath and select the Symbol Drawing (.dra) for the downloaded part. Note: If you are unsure of the name it can be found in the value of the “PCB Footprint” package property of the OrCAD Capture symbol.
- OrCAD PCB Design Flow. As you can see, OrCAD PCB Designer Flow consists mainly of two parts. −These are the schematic capture module Capture and the layout module OrCAD PCB Editor. Both modules are supplemented by additional sub packages who represent in each combination an.
- OrCAD is built with an open architecture, allowing for easy and powerful customizations to the platform. Whether you are trying to automate a small process or better integrate OrCAD into your business, OrCAD makes it possible. Download Free Capture Apps.
In the Footprint Viewer Type section, specify the footprint viewer to use. To view footprints with Cadence Allegro OrCAD PCB Designer/Editor, enter this statement: type=allegro; The Allegro Footprints sections define the location of the footprint libraries for the viewers. When building a list of viewable footprints, Capture looks at all.
There are a ton of pre-drawn components in the PSpice library. I’d rather use one of these as a starting point for my design instead of having to create my own from scratch. This post details how to copy an existing symbol and attach an external Pspice Model.
Open Orcad Capture and create a new library. Save it as something intuitive.
File-> New Library
Open the library with the symbol you want to copy. I’m going to use the FDC6322CP Symbol from my Fairchild library file.

Right Click->Copy the symbol.
Right Click->Past on your library.
Right Click->Rename the part.
Right Click->Edit part
Right Click->Rename the part.
Right Click->Edit part
Options->Package Properties
Change Reference to Q
Change PCB footprint to FDN340P.

Orcad should be able to locate your footprint if you enter it’s name in “PCB Footprint.” If not, you may have to add your directory in the capture.ini file.
Locate (Install Directory)toolscapturecapture.ini
There should be a section similar to this in the file. If not, add what is necessary.
[cc]
[Footprint Viewer Type]
Type=Allegro
[Allegro Footprints]
Dir0=Footprint Directory
Dir1=Secondary Footprint Directory.
Dir2=Third….etc
[/cc]

Finally change the part name and your symbol is set up.
Attaching a Model:
Orcad Footprint Viewer App
Fairchild provided a .mod file for the FDN340P while Orcad is looking for a .lib file. After opening the original parts pspice text as well as the new .mod file I determined that they were both in the same format. Renaming the .mod to .lib should allow me to associate the new model.
One problem with the new model is an extra pin which seems to be some type of internal temperature monitor. Since our symbol only has three pins we will not be able to associate the two. Unfortunately, I don’t yet know enough about the Spice model language to fix this so I am just going to add a temperature pin to the model. Things seem to get a little messy with pin placement so you may have to switch snap to grid off and do some manual alignment of the symbol.
While you’re at it you can right click the symbol and view footprint to verify that the symbol and footprint are correct. In this case the pins are numbered wrong on the symbol which is causing them to be mapped incorrectly.
After renumbering the pins your footprint should match the datasheet, as shown below.

Close your active windows until you are back to your library window. Right Click and choose “Associate PSpice Model” to attach your downloaded model. Browse for the renamed .lib file and a matching model should show up in the window.
Finally, configure the pins as defined in the model comments. Click finish and the model is complete. After saving this symbol can be used in capture schematics, both for simulation and PCB layout.
