2.4.1. Clock Constraints
You must define all clocks and any associated clock characteristics, such as uncertainty, latency or skew. The Timing Analyzer supports .sdc commands that accommodate various clocking schemes, such as:
- Base clocks
- Virtual clocks
- Multifrequency clocks
- Generated clocks
You can verify correct implementation of clock constraints by using Report Clocks (report_clocks) to generate clock timing reports. You can use Check Timing (check_timing) to report problems with a variety of timing constraints, such as missing clocks.
