I have the following schematic with 2 opamp. I have to do a transient analysis and eventually find the slew rate of the opamp. My simulation parameters are:
- Run to time: 1ms
- Step size: 1us
Any suggestions on how to fix it ?

\$\begingroup\$ Sorry, I don't have PSpice, but here's a a couple generic SPICE suggestions. (1) Try different opamps. (2) Increase TR and TF of the pulse source. (3) Add a small series resistor (10mohm to 100mohm) between the supply voltages and VCC/VEE nodes and also 100nF capacitors to ground on those nodes. \$\endgroup\$– Ste KulovCommented Oct 14, 2020 at 11:20

I fixed it. My problem coming from the wrong GND on the left of my schematic. Link
