How to extract cells:

1. Edit ~/projects/efabless/tech/SkyWater/EFS8A/libs.tech/magic/EFS8A.tech
 - on line 3297 to look as such:
 device mosfet pshort scpfet,pfet pdiff,pdiffres,pdc nwell vdd!
 - on line 3300 to look as such:
 device mosfet nshort scnfet,nfet ndiff,ndiffres,ndc pwell,space/w gnd!

that is to say, add the vnd! and gnd! at the end of the line

 - delete line 3088: "variant(sim)" and move it to line 3247

 - add line 594: "units angstroms"

 - starting from line 857 it should look like

 layer LI allli
    calma 67 20
 layer LI1TXT
    labels  allli noport
    calma   67 16
 layer LI1PIN
    labels allli port
    calma 67 5
 layer LIRES rli
    labels rli
    calma 67 13

2. bash extract_all

3. csh clean_all
if you want to delete all the extracted junk
