Hello,
I’ve tried to download the PSpice model of OPA1644, and run a simple simulation in Altium. But it always stops, and gives an error message:
XSpice Error: Syntax error in expression on line: 182
Line 182 contains the following:
E1 VOUT+ VOUT- VALUE={LIMIT(GAIN*V(VC+,VC-),VPOS,VNEG)}
I realise, that Altium uses XSPice and not PSPice. Is it possible, that this causes the problem? If yes, how can I fix this?
Please help!
Gábor
Gabor,
I am not sure what causes the error in Altium but some simulators do not recognize the initial state condition (IC=).
I removed all such statements from the netlist - please try to re-run your simulation using the attached netlist.
