I am using virtuoso 617 to do the auto-route by chip assembly router. However, there are some drc errors. I found out online that designer can import icc.rules file to define minimum width and spacing at old version like viruoso 5141. However, I can locate a place where I can import icc.rules file at virtuoso 6.1.7. Can anybody help me or this version has automatically applied icc.rules?
The Chip Assembly Router uses contraint groups to define the rules under Open Access, and not a standalone icc.rules file. There is a flow to translate the icc.rules into a constraint group - see How to translate multiple rule files of VCAR in one go from CDB to OA using cdb2oa for more details.
