How to find the Spice models for all the schematic symbols

RohitRohan
RohitRohan over 1 year ago

Is there any website and place to get all the Spice models for schematic simulation just like how we get all the schematic symbols, footprint and steps models from online libraries like Ultra Librarian and SamacSys. Because a lot of time when i am create a circuit for simulation some parts don't have Spice models and i have to search for the respective websites for IBIS file or LIB file so that i use for schematic simulation.

    With the tool installation you get a set of PSpice libraries that you can use in your designs. There are thousands of PSpice models available in the installation directory.

    All the parts present at below location are PSpice supported 

    <installation_directory>\Cadence\SPB_XXX\tools\capture\library\pspice

    Their corresponding models are present in <installation_directory>\Cadence\SPB_XXX\tools\pspice\library

    Hai Ayush, actually i am able to get the spice models from the Cadence pspice libraries but there are certain parts for which the Spice model is not available, i had searched for the .lib file .ibis file and .txt file in there official website but could not find any Spice models. Is there any website that i can search for them, or should i contact the OEM for the Spice models.
