Why TRACE did not detect violation in LSR pin, but during simulation, it was detected?

The static timing engine does static timing analysis only. The LSR pin is not a clock pin and pulse width requirement on this pin must be guaranteed by the designer. The static timing engine doesn't check for pulse width on the LSR pin. Simulation is the proper way to verify that the signal meets the requirement.
