Level=25 Model Released in SmartSpice
The Berkeley BSIM3SOI model, released in December 1997, is now available within SmartSpice as the MOSFET level=25 model. This model incorporates three separate implementations: the original Berkeley model implementation is invoked with the selector Berk=2; the Silvaco implementation is invoked with Berk=-2. The older Silvaco implementation, of October 1997, is also supported, under the selector Berk=-1.
All implementations produce virtually identical results when commonly accepted model parameter sets are used. However, the Silvaco Berk=-2 implementation supports a number of additional parameters and options, and provides certain improvements compared to what is supported in the Berk=2 (Berkeley) and Berk =-1 (older Silvaco) Level=25 models.
