When using CM for a design, do the DCF files have to be full and complete or can I set up subset DCF files for things like an 6mil region, 8mil region and 10mil region and then only import these separate files as needed? So if a design only needs a 10mil constraint region I only import the 10mil DCF file?
If so, how do I set up a subset DCF file? Is it a manual edit?
