Hallo Tim,

   I'm using 7.5.95 and the cifwidth DRC check. I find that the values have to
be twice the checked value. Eg.

style pharosc013 variants (55nm-vsclib)
variant (55nm-vsclib)
cifstyle pharosc013(55nm-vsclib)
# POLY RULES
cifwidth   CPG 24                 "3.1.01  POLY  Width < 0.12"
cifspacing CPG CPG 20 touching_ok "3.2.01  POLY  Space < 0.20"

The spacing rule is OK but to check for a 0.2um width the value must be 24
instead of 12.

Best regards, Graham Petley
