I am trying to verify above DRC error (Enclosure rule).
This is what is there in the assura rule file.
L48775=geomStraddle(Nwell Nburied)
L92003=geomAndNot(L48775 Nburied)
errorLayer(L92003 "NBL.E.1: Minimum Nburied to Nwell enclosure >= 0.2 um")
L91383=drc(Nburied Nwell enc<0.2)
errorLayer(L91383 "NBL.E.1: Minimum Nburied to Nwell enclosure >= 0.2 um")
Why do we need geomStraddle & geomAndNot ?
cant we directly use enc < 0.2 i.e last two line to verify this rule ??
Please explain.
