Hold Slack

Multicycle paths and false paths in STA explained for physical design and timing engineers: how set_multicycle_path moves setup and hold checks, why setup N needs hold N-1, -start vs -end across clocks, valid and dangerous false paths, clock groups, exception precedence and a debugging flow, with illustrative examples and interview Q&As.

Understand setup and hold time, calculate setup and hold slack with worked examples, and learn how to fix setup and hold violations in physical design.
