I have a core containing a multiplier. When I synthesize with class.db it works. What is class.db? I mean what technology is it? The performance is very poor. When I set link_library and target_library to typical.db from tsmc 90nm library the process crashes. Why is this? I see the synthesizer infers designware cores, should it not infer cores from the library? I am new to Synopsys DC and its all very unclear to me. I hope someone can clarify.
