We are starting to use IND2007 netlist flow (we use Dx for front end and Allegro for back-end). To our surprise we found out that there is no way to implement design sharing (libraries) in this flow. About 60-70% of pages of our design come from shared blocks so this is a show stopper for us. Is there a way to implement any form of schematic sharing (other than copy-paste between designs - which is a no-go for obvious reasons)? Are there any plans of implementing proper library support in netlist flow?
