#113 LEF 5.6/5.7 support for tapcells class: CORE WELLTAP Issue opened by msaligane Expected Behavior Tapcells have class CORE and should be CORE WELLTAP which is a LEF 5.6 construct and the LEF is 5.5 The script that prepares the LEF files from magic, which would need some additional handling to note that the cell name is "tap" as follows: "property LEFclass {CORE WELLTAP}". Actual Behavior When using the current LEF files: check_placement (openroad) reports a bunch of overlaps because the tapcells have class CORE in the LEF file. @RTimothyEdwards says we could change the LEF version from 5.5 to 5.7 in the file but there are small incompatibilities such as "SOURCE" line, it needs to be removed as it was deprecated in 5.6. google/skywater-pdk
