Introduced: January 2020

Title

Titles differ between systems:

IPC: Design optimisation, verification or simulation

CPC: Design optimisation, verification or simulation (optimisation, verification or simulation of circuit designs G06F30/30)

Full Title

Full titles differ between systems:

IPC:

Computer-aided design [CAD] > Design optimisation, verification or simulation

CPC:

Computer-aided design [CAD] > Design optimisation, verification or simulation (optimisation, verification or simulation of circuit designs G06F30/30)

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

IPC defines codes here since 2020.
