Not sure if this is the right place to ask, first-timer here.

I don't know how to work with op-amps in spice. I need to make the opamp have some slew rate and other effects. Can anyone lead me to documentation on how to do that? I am providing you with my assignment question for people to know what I mean.

Question:
Use two different models of op amp behavior. The first model is an ideal model of op amp behavior (at least, a close approximation) and the second model will be one that includes small and large-signal effects. Model the op
amp with a 2 MHz unity-gain bandwidth, slew-rate of 1 V/μs and an output saturation level of ±10 V.

You probably want to run two separate analyses on this....one being a step (transient) function, and another with a swept AC wave. Between the two, you can learn almost everything you need to know about the little feller.
