Hello every one,
For one certain design, data path almost has no margin, so i have to fix setup violation by useful skew. So i check slack margin before/after violation path and set_clock_tree_exception on clock pin.
While the result is, some violation was fixed by early/delay clock pin, but some new violations appear. So i am confusing , how i can fix violation by useful skew and don't cause new violations?
Thanks,
