This means that there are some LTSpice models that do not exist in the Altium Mixed Sim. Likewise, the XSPICE extension underlying the Altium Mixed Sim simulator also has a number of primitive models with instance descriptions beginning with the letter "A".Īnd here is an important point - sets of additional LTSpice and Altium Mixed Sim models do not overlap. LTSpice is an extension of the Spice 3F5 language and has a number of additional primitive models, the description of which begins with the letter "A". Unsupported model type 'A' error on LTSpice models:Īccording to the syntax of SPICE simulators, each instance of a primitive model must begin with some reserved Latin letter. 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.
