"STATESET" SPICE Model Ensures Simulation of Nonlinear Circuits 
Jul 1, 2011
SPICE simulation's historical shortcoming of permitting multiple DC operating point solutions for non-linear design, as in control systems, is mitigated by STATESET's furnishing a new circuit branch where the element output is initialized during the entire DC operating point calculation. It linearizes control law equations and can also work in conjunction with GFT modeling to help establish STATESET's initial condition....

SPICE Simulation Provides Significant Advantages For a DSP-Based SMPS:Part 2 
Apr 1, 2009
The techniques presented in this article will show the advantages of using special device models with a SPICE simulator to simulate the digital control algorithms for DSP, and advantageously create corresponding instructions to program the DSP's CPU through a development board. Such techniques will also minimize the total parts count in a DSP-based switchmode power supply design by putting their functionality into DSP firmware. Part two provides the results of a target design....
