In the meantime, the only workaround conceivable is to find another equivalent/similar model or to negotiate with the manufacturer to obtain a decrypted model. There is a BC to have Altium work with device manufacutrers to establish equvalent encryption scheme for Altium, that you may upvote/follow to get any update: Device manufacturer encrypts its model for the purpose of protecting their IP, so it can be decrypted solely by the known designated tool. Models encrypted for a particular simulator can be used in that simulator exclusively. !sourcing-a-simulation-ready-component-from-the-manufacturer-part-search-panelĮncrypted PSpice/LTSpice/HSpice/TINA-TI models: Our long-term intention is to have spice models linked upfront to wider range of components you can save/download directly from Manufacturer Part Search panel: The older file extensions will still be recognized. New in AD21 is a *.LIB model file extension.

Prior to Altium Designer 21, it was necessary for Spice models to have the correct file extension to be recognized.

Starting with Altium Designer 21, some support was added for both PSpice and LTspice model variants.Ī device manufacturer site is the first place you may look for a model of most accurate representation, but for a simple/casual model, you may opt to create one yourself. Altium Designer supports SPICE2/3 and XSPICE.
