This distribution contains sources for building out the SkyWater SKY130 130nm process. Sources for the foundry process data must be obtained separately. Read the README file in subdirectory sky130/ for instructions on obtaining and building the SkyWater sky130A PDK.

git clone https://github.com/RTimothyEdwards/open_pdks.git cd open_pdks ./configure [options] make [sudo] make install
where the configure [options] are specific to each foundry PDK supported by open_pdks and can be queried using
At a minimum you will want to pass a configure option to declare the PDK that you want to build. It is possible to build multiple PDKs at once, but not recommended due to the large memory and disk space overhead required by each one.
The open_pdks version of the PDK can be built locally within open_pdks without the need to declare an install target or run “make install”. However, it is highly recommended to declare a target location and install there, using
./configure --prefix=[path] --enable-[PDK_name]-pdk
followed by “make” and “make install”. The default install location is /usr/local/share/pdk ([path] above is /usr/local). The install location should be a read-only filesystem area for regular users, since the PDK contents should not be altered.
