Does Cadence provide a standard Python API for tool automation?

WM20250906725

Does Cadence have a standard Python interface, similar to how Cadence has an interface with MATLAB?(Is there a Python interface for Cadence Virtuoso?)

Parents

  • We have Python interfaces for specific things - for example:

    • There is something called CDSPYTHONSRR which was introduced in IC23.1 ISR12 (it was available as a standalone kit on request before that) which allows you to read simulation results directly into Python. This doesn't cover everything that you can do with the MATLAB interface, and there's no integration into ADE (so you can't have python expressions in the output). There's an enhancement CCR for that - 2052789 - with a few duplicates. If this is what you want, you should contact customer support (submit a case after logging in) and request a duplicate is filed on your behalf.
    • There is a capability with Spectre (Spectre Interactive) which allows Spectre to be controlled using Python or Tcl
    • The Advanced Optimisation Platform provided as part of the Virtuoso Variation Option or ADE Artist gives the ability to integrate a custom optimiser algorithm using C++ or Python.

    There is not a general Python interface that can be used to customise Virtuoso though; the customization language is and remains SKILL.
