    adding routing constraints in OA Reply

    Hi,

    I want to use Virtuoso Custom Router or Virtuoso Chip Assembly Router to route automatically parts of layout design. I see differences in defining routing constraints in CDBA and OA. In CDBA lpps can be specified as keepouts for other lpp-s in the iccKeepouts section of the VCR file:

     list( "=>" list( '("keepout_layer" "keepout_purpose ) '("routing_layer" "routing_purpose")  "routing" t )

     

    In OA the syntax is different and I am not able to find how to specify lpps instead of just layers...

     keepouts =
        keepout_layer => routing_layer

     

    Can someone please point me to some documentation that I am missing.

    Thanks!
