How to use pspice model instead of spic to create new component ?

[fouda]

Hi , I need to create model to opa890 from TI but I didn't find spice model  I find pspice model how to use it to create new component.

Hi,

Multisim supports most of PSPICE syntax, have a look at this tutorial to create a custom part:

If you have any problems, let me know.

I did it but this error appears when i try to simulate opa890 alone

Hi Fouda,

              Can you place the component that you created on a multisim blank page and then save and post the file. I want to take a look at your component.

Thanks.

thanks in advance

Hi Fouda,

               I took a look at the component but for some reason, the pspice model did not get properly applied to the component. The second problem was that the pins were not mapped properly. I have made the component for you with the model and footprint and attached it to this post. You just need to add it to your database by right clicking the component and clicking Save component to DB.

Hopefully, you should start seeing the desired results from the component. Hope this helps.

Best Regards,

thanks very much
