Sure. At first you need the drcexpander.pl from https://github.com/thesourcerer8/caravel_stdcelllib_stdcells_project/blob/main/scripts/drcexpander.pl which annotates the magic .tech file with the correction strategies.

I haven't looked at a real perl script since ~2001. Why'd you choose perl?

I am too much used to perl after 25 years and more than 100k lines of code developed in it

I forced myself to switch to Python back in 2008, I think. I wrote a lot of perl from 94-01, but it is a pain to maintain.
