For gate-level simulations these values will be updated by the back annotated SDF. terminal matlab kya hota hai

"WebMetastability is an undesirable effect of setup and hold time violations in flip-flops where the output doesn’t settle quickly at a stable ‘0’ or ‘1’ value. If the input changes too close to the triggering clock edge, the flip-flop output is undetermined. We can’t know for sure whether it’s going to be ‘1’ or ‘0’. " - Setup hold timing
