Clearly my opamp isn’t working. I’m using the OPAMP out of the pspice librarly (although confused, because there’s also an OPAMP in the “Simulation_SPICE” librarly (which also doesn’t seem to work). Maybe it’s my power connections?
When running the simulation I’m getting:
u1 0 net-_r4-pad2_ net-_r5-pad2_ vcc vdd opamp
Unable to find definition of model vcc - default assumed
unknown parameter (vdd)
Thanks for the help… I just want to simulate a few filters.
An Opamp model for ngspice simulation is missing.
Please have a look at http://ngspice.sourceforge.net/ngspice-eeschema.html, especially at http://ngspice.sourceforge.net/ngspice-eeschema.html#OpAmp.
See also the example for a Sallen-Key-Filter at KiCad\share\kicad\demos\simulation\sallen_key.
Yikes! I super appreciate everything that KiCad has become and all of the work that has gone into making it a very useable PCB design and schematic capture program.
But if that is the level of nerdery that is required just to get an op-amp working in the simulator, then I will need to find another simulation program. I was previously using LTSpice but because drawing a schematic was so different than KiCad I always had to re-learn everything, so the idea of EESchema doing some simulations for me was ideal… but I will have to wait until this feature matures and improves. I appreciate you offering help though, thank you.
