Problem running PSpice simulation from OrCAD Capture

RaggMopp

The first simulation example in the PSpice User's Guide is made up of 2 voltage sources, 2 diodes, 4 resistors and 1 capacitor. When I  run the simulation from OrCAD Capture, it fails with: "ERROR(ORPSIM-15090): DC device Vin is undefined".

 I found that I can edit the PSpice netlist file to get the simulation to run in SPice A/D primarily by changing the second voltage source name from V_V2 to V2. 

 Anyone know why that is? And, what I can do in OrCAD to "correct" the PSpice output.

ERROR(ORPSIM-15090): DC device Vin is undefined

    Your simulation profile is trying to run a DC Sweep of device Vin, you have no device Vin, in your netlist Vin is a net, V2 is the device to sweep the voltage at net Vin, change the Voltage Source in the Sweep to V2 and the simulation will run correctly.
  • RaggMopp

    Thanks, that was helpful in that it guided me to the answer to my original question.

    So, to sum up, the information in Chapter 2 - Figure 6 - DC sweep analysis settings in the PSpice User's Guide, Second Edition 31 May 2000, is incorrect in one regard. When setting up the Simulation Profile, replace Voltage Source Name: "Vin" with the source name generated by OrCAD which, in the case of the example, becomes "V_V2". The simulation will then run correctly from OrCAD Capture.

  • oldmouldy

    I don't have access to a version of the Users Guide that is so old BUT, I suspect that you missed the Steps to name the IN net and change the RefDes of the swept source to Vin (from the likely default of V2) along the way. Things would then work correctly.

  • RaggMopp

     If "Vin" had worked, we wouldn't be having this conversation. Naming the IN net has no effect.

    So then, since I am annoyed, I will critique what appears to be an incomplete attempt to edit a correction to the problem in the PSpice User's Guide.

    In the latest online PSpice User's Guide a new figure is added: Figure 2-5. The difference being that the two sources are hardwired into the schematic diode clipper. At least, I assume that is the change, since the figure called "Diode clipper design" is still labeled 1-1 and the "Figure 2-5" links don't actually link to anything.
