ADIsimPE runs on the SIMETRIX platform and supports most SPICE models, in particular PSPICE. It is able to import simulation models from many sources as described in this knowledge base posting.
All ADI devices included in the installation library are encrypted to extend the node limitation. Other imported PSPICE models will be able to run if they do not exceed this limitation. It is possible to combine ADI parts and other imported SPICE models while extending this node limitation.
For mode details about node limitation please see the SIMetrix Intro version.
