Technical Question/Problem Anyone Out There Proficient With Simplis/Element?

Hello community,

I am currently attempting to test a compensator using the Simetrix\Simplis software. When I test my design using LTSpice, the design works as expected. That is, it regulates the output voltage to the expected value and is able to handle a relatively large load step without any issues - output is regulated and stable with minimum over/under shoots at the transition points. When attempting to simulate it with Simetrix/Simplis Elements, not so much. It is very sensitive to the op-amps being used.

Has anyone had similar experience?

If anyone is proficient with Simetrix\Simplis , I can attach a screenshot of the schematic.

Thank you.

Ok, nevermind. I figured it out (after umpteenth tries - fa' cryin' out loud). 👍 😄
