Introduction to MOS Model PSP
The PSP model has been developed jointly by NXP Research (formerly part of Philips Research) and the group of Prof. Gildenblat at Arizona State University (formerly at Penn State University).
- suitable for digital, analog, and RF;
- suitable for modern and future bulk CMOS technologies;
- physics-based;
- combining the best features of SP model (Penn State University) and MOS Model 11 (NXP);
- number of parameters and simulation time comparable to MOS Model 11;
- simple parameter extraction.

Model definition of MOS Model PSP
The model definition of 
MOS Model PSP level 102 and
MOS Model PSP level 103 are available
in PDF format.
The history of the PSP model can be found here.
The PSP model is a surface-potential based compact MOSFET model, containing all relevant physical effects (mobility reduction, velocity saturation, DIBL, gate current, lateral doping gradient effects, STI stress, etc.) necessary to model present-day and upcoming deep-submicron bulk CMOS technologies. Unlike previous NXP MOS models, the source/drain junction model, c.q. the JUNCAP2 model, is an integrated part of the PSP model.
MOS Model PSP 103.0 is not backwards compatible with MOS Model PSP 102.3 and contains various improvements and additions.
Source Code & Library
The source code (i.e., C-code and Verilog-A code) of MOS Model PSP level 103 and PSP level 102 can be found here. The C-code files are called device_psp103.c, device_pspnqs103.c for level 103 and device_psp102e.c, device1020.c, device1021.c, device_pspnqs102e.c, device_pspnqs1020.c, device_psp1021.c for level 102. If you use the included solver, please make sure that you compile on a system that supports Fortran 77.
The source code for MOS Model PSP has been automatically generated from a Verilog-A description of the model.
The history of the source code can be found here.
The models are included in a dynamically loaded library called SiMKit.
SiMKit is related to the following circuit simulators used within NXP:
- Pstar, the circuit simulator from NXP
- Spectre, the circuit simulator from Cadence
- ADS, the circuit simulator from Agilent.
You can read how to download and install the libraries here.
