CDC violations are now so complex that it takes a combined block and full SoC level verification strategy to catch and fix all the bugs
Performing clock-domain crossing (CDC) checks on a flat database is difficult on complex SoCs. Hierarchy improves speed but calls for a smarter approach.
This article looks at the way in which various representations of a block of a design have different implications in a UPF based power-aware hierarchical design flow.
Using hierarchy and improved constraints management to accelerate static timing analysis at 20nm and below.
