Dear Sir, Some of my vbe file give error during making .cif file : s2r -cv <filename> <filename> The error is "At line 11 unknown layer". To some file this kind of error gives if I use cmos8.rds as my RDS_TECHNO_FILE. But if I use prol10_8.rds technology file the same vbe don't give any error. It cam make .cif file. But if I use prol10_8.rds. I can't use DRUC commamd. It gives error "cann't open input file". What is the differecne between prol10_8.rds and cmos8.rds. ? How can I use cmos8.rds for those file which give unknown layer problem? What I have to do to use "druc" command with prol10_8.rds?
