# This script tries to follows the instructions in the README @
# https://github.com/RTimothyEdwards/open_pdks/tree/master/sky130 with a couple
# of differences;
# 1) It uses the git repositories already cloned by Kokoro
# 2) It runs inside a Docker container

# Cleanup any existing docker build
docker stop --time 0 builder || true
docker rm builder || true
rm -rf out

# Start the docker container to do the build inside.
docker run -dt \
  --mount type=bind,source="$(pwd)",target=/host \
  --name builder \
  debian || docker start builder
