Added resistor type short as a custom modification to the device models. Changed "obslic" (li-m1 contact as an obstruction layer) to be defined not between obsli and obsm1, but between obsli and metal1. This is consistent with the use of obsli in the standard cells with the LEF files generated using the "-toplayer" option, and allows metal1 to be placed across the power rails and obslic contacts without generating DRC errors.
Summary:
Automatic setup of PDKs for open-source tools from foundry sources.
Builds out and populates a new set of directories and subdirectories in the efabless format, with the efabless name for the PDK at the top, followed by categories “libs.ref” (IP) and “libs.tech” (EDA tool setup), each with subcategories corresponding to layout, abstract views, netlists, etc. for the IP; and magic, netgen, qflow, etc., for the EDA tool setup.
The populated PDK directories can contain either copies of files from the foundry sources, links to the foundry sources, or links back to another PDK.
Generates magic layout views for all vendor IP for which either a GDS view or a LEF view exists. Annotates the views as needed to handle ports, bounding boxes, etc.
This distribution contains sources for building out the SkyWater s8 130nm process. Sources for the foundry process data must be obtained separately. Read the README file in subdirectory s8/ for instructions on obtaining and building the SkyWater s8 PDK.

Instructions:
There is a top-level Makefile but generally it is recommended to cd to the directory for the target foundry process and follow the instructions in the README file there.
