1. RC version is 10.1, CONFORMAL version is 91.400
-- In order to reduce design area, I turned on boundary_opto in RC flow and then LEC failed.
-- Same design, almost the same script, turned off boundary_opto, LEC can pass
2. RC version is 91.102, CONFORMAL version is 91.400
-- almost the same design, same script, both turn-on and turn-off boundary_opto can pass LEC
I don't know what happened.
