When I check the result of "report_analysis_coverage" about "min_pulse_width", one case as following:
aaa_reg/CDN(low) min_pulse_width untested no_clock
actually, the clock source of aaa_reg is CLOCK1, and the CDN is signal double sync from CLOCK1.
When I report timing for "aaa_reg/CDN", is does exist.
But why it is reported as "no_clock"???
