OPA627 problem ngspice.dll

Hello,
I try to simulate a OPA627 with Kicad but I have a problem.
I imported the spice model and put the file in my project folder but when i try to simulate a i have this errors :
No compatibility mode selected!

Error: there aren’t any circuits loaded.

Can you help me to find a solution please ?

It may be necessary to do the following step (setting the compatibility):
Inspect → Simulator → Sim Parameters → Compatibility mode → PSPICE and LTSPICE

Hmmmm…I’m starting to think this maybe should be the default and you have to use the checkbox to disable it instead.

I agree. All simulations seen here, using off the shelve components, will use PSPICE (LTSPICE) compatible models.

This selection is mutually exclusive to using HSPICE process devvelopment kits (PDKs), which is not a KiCad/Eeschema application, but for IC designers only. So no primary problem.

Would you set up a bug (wish list) report?

Ummm…no can do. I don’t have an account and don’t want to set one up for software I never use outside of offering assistance here. Plus, I am on Windows 7 and can’t use KiCad 6. Sorry, I was just throwing out a suggestion simply to see if there was agreement.
