hello all,
Is it common in first maskset to tapeout with some WNS on some of the paths? WIll you still signoff STA as ok and go ahead with tapeout.
I understand this depends on the design and how conservative various design constraints are setup, etc etc.
But if the timing constraints and clock are setup very aggressive, it is likely to fail. If the WNS is 1-2% of the clock period, do you think it is ok.
The reason I ask this Q is because my product got tapedout with some marginal WNS. When I checked with the project lead he said those are usually ok when the silicon comes out.
Let me know your thoughts.
Thanks.
