Compact Models (SiMKit)

Compact models are mathematical descriptions (equations) of semiconductor devices used in analog circuit simulators. NXP has a simulator-independent compact transistor model library, called SiMKit. Here you can find the latest model information and downloads including full documentation as well as the complete SiMKit source code.


What's New on 4.6

Version 4.6 of the SiMKit library is now available. On this website, previous versions can be found as well. The main developments of this release are:

  • DC-match available for MOS1101 and PSP103
  • Correct transient noise simulation now possible with PSP
  • Better control on OV check messaging

Note: SiMKit 4.6 is the last version that provides support for Windows
