Hi @Matt Venn @Mitch Bailey @Tim Edwards Can anyone tell me how do I check the Antenna violations at the caravel level?

Sorry, I don't know.

There is a script in the PDK under

libs.tech/magic/check_antenna.py

, although it should probably be expanded to handle GDS files as well as .mag files, and to run

antennacheck debug

before

antennacheck

so that the output is more verbose. I thought that there was a precheck script that runs antenna checks, but I can't find one.

How to I expand it? @Tim Edwards can you help me out?

You could just hack a local version to replace the

load

command with

gds read

.
