Constraints state what synthesis must hit, and timing analysis scores every path. SDC clocks, IO delays, and exceptions set the targets, while arrival, required time, and slack find the critical path. Timing-driven synthesis then spends restructuring and sizing where slack is worst.

Margin beyond the real target spends area and power on a fiction and can push the tool into structures that hurt the true paths. The Timing-Driven Synthesis topic shows where margin helps and where it harms.
