I keep getting this error when trying to simulate the shown pspice model (I'm using the 17.4 version). Should I click on "Edit part" and modify something? I don't know how to solve it. Any help would be appreciated
1M is 1e-3 in SPICE syntax, giving 1 s time constant for the oscillator circuit.
You are showing a warning, not an error message. The simulation may work or not, but you don't give sufficient information to decode the warning. Basically a problem of component definition. Simulation doesn't care for footprint definition however.
