(April 20, 2021) – AEi Systems, the world leader in worst case circuit analysis (‘WCCA’) and SPICE modeling, has released version 4.4 of AEi Systems’ Power IC Model Library for the Cadence® PSpice® simulator. The updated library includes a variety of new models including many semiconductors (diodes, FETs, BJTs, and zeners).

Version 4.4 of the Power IC Model Library now has over 1,200 high fidelity and correlated simulation models for power electronic designs. It includes model netlists in PSpice syntax, schematic symbols for both Cadence OrCAD® Capture and legacy schematics, and a set of example application circuits for many of the IC models. The models are compatible with the latest OrCAD Capture version 17.x software.

New additions for version 4.4 of the Power IC Model Library include:

“Many models on part vendor web sites and that are included with EDA software packages are of poor quality and fidelity. They aren’t always vetted against test data or even their own data sheet” said Charles Hymowitz, managing director at AEi Systems. “They aren’t always constructed to exhibit the key part characteristics designers anticipate they will have. They aren’t documented. They often give inaccurate results at extreme but valid operating conditions. AEi Systems maintains a much higher standard with respect to the models we create and the support we provide.”

The Power IC Model Library for PSpice also includes:

The Power IC Model Library is available immediately and priced at $1,995, plus yearly maintenance of $495. While the model count has increased, the pricing has not. Existing customers on maintenance can download the updated version as part of their maintenance contract.

More details are available here, including a list of the components and documentation detailing the models’ accuracy and performance.
