Design Challenge #2

Spice component models are mostly text files with component parameters and specs that can be edited. Mouser and others include Spice model documents along with the normal data sheet.
If you place the file in your library include path, it should find it as a listed component.

Here is a link to the SPICE model for the CD4049UB from Mouser. Hope it helps!

This lib is for logic behavior of CD4049UB, and that is now what we need for audio simulation.

"now"? I think you mean "not"

I agree, those models won't work for analog simulation.

There are analog models for the N and P devices in the CD4007 and CD4049. I use those in my sims. Pretty close match to breadboard test data.
