Technical guidance on Cadence-Python Co-simulation

VLSI lab IITB

Greetings,
I hope you are doing well.

I, Vatsal Patel, request you to provide technical guidance on Cadence-Python Co-simulation. What I wish to do is the following:

I am using cadence virtuoso ADE for circuit simulations, inputs specified in a vector file (.vec). I wish to extract the simulation results and give them to a python script for post-processing. Based on the outputs of this python script, I will update the vector file which will now contain the updated inputs, and the loop continues. This loop will repeat a significant number of times and hence cannot be done manually.

I don't think I am the first to encounter such a situation. So I was wondering if there already exists such integration in cadence. If yes, Can you send me its details and documentation? If not, Any insights into how the above problem can be solved would be much appreciated.

Kindly acknowledge the receipt of this mail and feel free to reach out to me if you require any further information/clarification.

Thanks & Regards

    My understanding is that this integration does not exist in public releases of Cadence tools.

    MATLAB is well integrated, but not Python. An alternative might be to create some ocean scripts to post-process simulation results and perform iterative simulations.

    Others who monitor this forum may have more information regarding a Python integration/interface, but this is my understanding (hopefully correct!!).

    Shawn's right.

    Also, being pedantic there's no such thing as "Cadence-Python co-simulation" because Python is not a simulator. I think you're just asking for the ability to post-process the results in Python, and there's no public release of an interface to read simulation results with Python, let alone an integration along the lines of the ADE MATLAB interface which allows you to add MATLAB expressions into the ADE output pane.
