Does anyone know how to check the mental density DRC in Klayout? I'm new to klayout

why?

I'm the wrong person to ask because I'm unable to get klayout to execute any command line options. But if you clone the mpw-precheck repository from github/efabless, there is a DRC deck for klayout called

met_min_ca_density.lydrc

. You can check online klayout documentation for how to run a

lydrc

file from the klayout command line.
