Good evening,
Here is a question on simulation in PSPICE.
I have the inverting op amp built in Cadence Capture CIS PSPICE program in the picture. Now a DC sweep is to be set up which is shown on line 26 in the code diagram, with a nested parametric sweep shown on line 27. The parameter is the resistor RF with value of a global variable {rvar} = 1000,2000,4000 as on line 27. Now. I have imported the library necessary for the op amp 741 subcircuit. But I cannot get rid of this error message line 43, which is "Invalid number." Since there is no more helpful information of where the invalid number is, I don't know what is wrong in the simulation. Some theories I had were {rvar} should be just rvar somewhere, but when I change that it only adds more error messages. So it is probably not a problem with the parameter list, rvar.
Thanks for reading. Any information would be very valuable if you have any experiences in Cadence Capture CIS, or other PSPICE...
