Hello there,
I am attempting to run a Altium SPICE simulation with the SPICE model for the IRS21876S, and I'm encountering a few errors. I keep getting a PWL error about an ngspice expression not being a constant. This confused me since there is no PWL source in the model. I'm not sure if this is a problem with the model or Altium, but I thought I'd post this here to help track down the issue. I've included a screenshot of the error messages with this post.
Solved! Go to Solution.

Hi Caeleb,
I tried to simulate Pspice Model of IRS21867S (driver) with the mosfet model IPW60R017C7 in a half bridge PWM converter configuration in ltspice environment and the model is working absolutely fine. Thus I can assure you that it will work fine in any of Pspice or ltspice environment. ltspice is a open source tool, you can download it and simulate your circuit. I would still not comment about ngspice, whether the model will work well there or not!
Please revert in case of any query

Rishabh,
Thank you very much for the help! I'll switch to ltspice for this task.
