AMS simulation error with bsim bulk model

andreschen

Hello,

The simulation environment I am using is IC618+INCISIVE15.2+SPECTRE19.1. Previously, I successfully ran simulations with a bsim4 model, both in the Spectre simulator and AMS.

However, after switching to a bsim bulk model with a different process, I can only simulate the circuit correctly using the Spectre simulator. When I switch to the AMS simulation environment, it cannot recognize the model.

Is it related to the environment version, causing AMS to not support the bsim bulk model?

If so, may I inquire about which version supports running bsim bulk models in the AMS ?

 

Thanks for your help.

  • Well, using a 8 year old simulator (INCISIVE152) is not that sensible. It's much older than the SPECTRE version (even your Spectre version is 3-4 years old). 

    You should be using an XCELIUM release (this replaced INCISIVE). For the last few years, XCELIUM uses the "flex" approach of using the analog solver from the Spectre release; historically it had a built-in copy of the Spectre engine - newer versions allow you to re-use the SPECTRE version you're using for everything else.

    I would recommend moving all your versions to something newer and supported.
