Simulation Error in PSpice

[mtajeldin]

Hi all,

I simulated the attached circuit but after running the sim, I am getting four errors:


"Reading and checking circuit
ERROR(ORPSIM-16153): unknown parameter
ERROR(ORPSIM-16145): unknown parameter
ERROR(ORPSIM-16153): unknown parameter
ERROR(ORPSIM-16145): unknown parameter
Circuit has errors ... run aborted
"

Could you tell me what might be wrong and how to debug the circuit from these numbers?

Thanks.

1.

I assume it's okay to label power supplies as a negative voltage, at the positive end of the icon?

2.

The power supplies to U1 appear to have the negative on top and the positive underneath. Is this permitted?

3.

If the above items are okay, then about all you can try is to
simplify the circuit. Delete a stage (op amp). Watch to see whether the errors stop. Then you'll know which stage is generating errors.

From the top nothing looks unusual.
If you are still facing the problem, you can post the netlist to have a closer look at it.
