AEi Systems has developed hundreds of SPICE models for discrete semiconductors, RF devices, power electronics, magnetic cores, linear regulators and dozens of other types of devices. If SPICE can simulate it, AEi Systems can develop an efficient model that provides the accuracy and performance you require.

AEi Systems is the world's leading source for accurate SPICE models.

If you have any questions about our SPICE Modeling and Simulation Services or you are interested in having AEi Systems develop a SPICE (PSpice, IsSpice, HSPICE, LTspice, SIMetrix, Electronic Workbench, or other) model for you please contact AEi Systems via email at, or by phone at (310) 216-1144.

"AEi Systems' models provide exceptional results. Their models correlate consistently with our hardware!"
