Restricted Fmax due to minimum period

I don't think you can refer to the table for restricted fmax.

Here is the definition:

Restricted Fmax considers hold timing in addition to setup timing, as

well as minimum pulse and minimum period restrictions. Similar to

unrestricted Fmax, the restricted Fmax is computed as if the rising

and falling edges of the clock are scaled along with Fmax, such that

the duty cycle (in terms of a percentage) is maintained. Refer to

hold timing reports (e.g., report_timing with the -hold option) or

minimum pulse width reports (report_min_pulse_width) for details about

specific paths, registers, or ports.

The report still doesn't show which nodes are causing the violation, but the help says to use

report_timing -hold

or

report_min_pulse_width
