I see a number of issues .. The version you are using (0.35) is not the latest .. try the snapshot 20091207 .. it has a lot of fixes relative to 0.35. You didn't say anything about the model .. it's some "X1" but that is all I can see. But the real problem is that your circuit doesn't work. You have an op-amp with only a capacitor for feedback, and sometimes the inverting input has no DC path to ground. You might think that the simulator should show something like what a real circuit might do .. output goes full + or full - .. I'm not sure which. What happens here is dependent on the model you use for the op-amp. Many of those models do not handle this kind of situation correctly. _______________________________________________ Help-gnucap mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-gnucap
