Unable to simulate and get the result of smoke analysis for certain type of schematic symbols

RohitRohan

Dear Community,

I have a schematic design, which consists of resistors, capacitors, inductors, analog ICs, GDT (Gas Discharge Tube) and Fuses, I am using the OrCAD PSpice Designer license Version 23.1 latest hotfix S006.

I am trying to run the Smoke analysis for the schematic design and I am getting the output, but in the result I can see there is no values for schematic part such as GDT and Fuses.

For Example, I have a GDT symbol which has a reference designator of U1, but in the smoke analysis result, I don't see the result for U1. Same goes with the Fuse result.

How to perform the Smoke analysis on schematic design containing schematic symbols link GDT and Fuse.

Regards,

Rohit Rohan

    Smoke parameters are maximum operating conditions for the component. To perform a Smoke analysis on a component, smoke parameters must be defined for that component. You can still use non-smoke-defined components in your design, but the smoke test ignores these components which seems to be the case with your GDT and Fuse.

    Can you check if smoke parameters are defined for these parts. For example: a resistor would have POWER= RMAX, VOLTAGE= RVMAX etc. You can find the list of smoke parameters for non passive components in the Pspice advance analysis  user guide, available here PSpice Advanced Analysis User Guide -- Smoke (cadence.com)
