I realize that asco only supports optimization in single analysis. I mean it could not optimize the circuit both in TRAN and AC. All the other tutorial examples only optimize in single analysis domain.
Or did I setup the sp and cfg files incorrectly ?
Note: I have updated below the measurement section in inv.cfg due to some syntax bug
1. How should I set the DC operating points for this asymmetric differential amplifier pair ?
2. For DC analysis, should I connect the IN and OUT to a feedback circuit which is the CMOS inverter in this case ?
3. Do I do the same for AC simulation for output impedance after determining the DC operating points ?
