Looking for a SKILL/Python Script to Automatically Run Schematic Netlist in Virtuoso IC23.1

AR202509246930

Hi Community,

I am using Cadence Virtuoso IC23.1 and am looking for a SKILL or Python script that can automatically run schematic netlisting by simply providing the library name and cell (schematic) name as inputs.

The requirement is to run the netlisting process without opening the schematic in the Virtuoso GUI or in the background. Ideally, the solution should:

  • Accept library name and cell/schematic name as inputs.
  • Run the schematic netlisting automatically.
  • Avoid opening any schematic window.
  • Support batch/automated execution.

Has anyone implemented something similar or know of any available SKILL APIs, Python scripts, or examples that can achieve this in Virtuoso IC23.1?

  • You didn't say which netlister you wanted. If it's an ADE netlister (e.g. spectre) then you can use:

    simulator('spectre)
    design("libName" "cellName" "schematic" "r")
    fileName=createNetlist(?display nil)

    You could then use "ocean -restore script.il" or "virtuoso -nograph -restore script.il" to run it (you could add exit() at the end too if needed).
