Unified Reliability Interface (URI) without RelXpert?

anla
anla over 12 years ago

Hi.

We would like to analyze the ageing behavior of our circuits runnig transistor-level simulations, but we do not have RelXpert licenses. Is it possible to evalute Unified Reliability Interface (URI) models in Spectre without using RelXpert? If yes, how can this be done?

Thank you.

    Hi André

    Yes. If you run RelXpert in spectre native mode, then it will run using only MMSIM tokens - you do not need the explicit RelXpert license.

    Regards,

    Andrew.

    Hi Andrew.

    Thank you for the reply. The simulations seem to run although we do not use RelXpert licenses.

    Nevertheless, we have trouble getting started. The recent questions are:

    -  Do you have an example on how to run reliability simulations in Spectre native mode (testbench & device models). We would like to run it with the dynamic library that we can generate from the example in $MMSIM_INSTALL_DIR/tools.lnx86/relxpert/uri/.

    - How do the simulation netlist and the model cards have to look like? Can we use either the reliability block or "*relxpert:" statements, can we use both, or do we have to use both depending on where the statement is placed?

    - Can we run such kind of reliability analysis from ADE-L? The checkboxes do not allow to specify a URI mode for the defined library if the simulator is Spectre native. I am pretty sure that simulations then use Agemos model, don't they? Is there a chance to turn on the debug mode (would be uri_lib file=<file> uri_mode=appendage debug=1 in the netlist)?

    Looking forward to your reply. Thank you.

    André

    Andre,

    Please could you contact customer support. Whilst I do have an example using the native models (and using URI), I can't send it to you - and also I'm pretty busy at the moment. So customer support would be the best avenue for such questions.

    Thanks,

    Andrew.
