Witryna(7)logically exclusive 与 physically exclusive set_clock_groups 这个部分还有一个点，不太常见，但我既然都说到这了就索性一并记录下来。 clock之间的关系一共三种： (1)asynchronous 时钟异步，自然无法分析timing。 WitrynaExclusive Clock Groups (-logically_exclusive or -physically_exclusive) You can use the logically_exclusive option to declare that two clocks are physically active …

WitrynaAs a result, the Timing Analyzer currently treats asynchronous, logically_exclusive, and physically_exclusive clock groups the same. However, different parts of the Timing …

WitrynaIn Synchronous clocks, events happen at a fixed phase relation whereas in asynchronous clocks that is untrue. Then there are logically exclusive clocks, which are passed through a mux logic, whereas in physically exclusive clocks, the sources are entirely different. set_clock_groups is used for establishing asynchronous and … Witryna3.6.1.3. Derive Clock Uncertainty (derive_clock_uncertainty) The Derive Clock Uncertainty ( derive_clock_uncertainty) constraint applies setup and hold clock uncertainty for clock-to-clock transfers in the design. This uncertainty represents characteristics like PLL jitter, clock tree jitter, and other factors of uncertainty.

Witryna1 sty 2013 · The options -logically_exclusive, -physically_exclusive, and -asynchronous are mutually exclusive. You can use only one option in a single set_clock_groups command. However you can specify relationships between clocks in multiple commands which could be different.
