#1052 Integrate Volare for PDK Building and Mangement, Part 2 Pull request opened by donn WIP * * * • PDK installation uses Volare, transparently to the user: all they have to do is type "make", where it will get OpenLane and the PDK • CI now uses Volare to either get or build the PDK (if not found), which speeds up the fastest test set by around 60%. • Added rudimentary dependency installation instructions. • pyyaml into the repo, so users without pip can still run issue surveys ~ Open PDKs updated: Parasitics are now extracted using a rules file based on spef-extractor as a temporary measure ~ Issue survey no longer checks for click and pyyaml: a venv is used in those scenarios. ~ OpenLane build no longer uses the host filesystem as an intermediary, instead using a templated dockerfile with an N-stage build for N tools, saving IO operations (40% improvement measured) ~ Old PDK targets renamed to build-pdk-conda, includes SRAM by default ~ Replaced python3 ./env.py issue-survey with

make survey
