Hi,
I have defined several clocks for my design, but the tool has removed some of them.
Quarus (ver 22.3) found these clocks, but I'm unsure why they are not included in the final clock list.
I'd like to share the "fit.plan.rpt" file with you, as there are some comments regarding these clocks that I don't understand.
Could you please provide me with a link to upload the file? ( file size is 4GBytes)

Hi,
Could it be that the SDC is being ignored? Try reporting "Ignored Constraints" in Timing Analyzer to see if they are being ignored.
Let me drop you an email and see if you can send it through there.
Regards,
Nurina

I found the issue,
I got a critical error:
" Ignored create_generated_clock , Argument -source is a collection with more than one object. "
It needs more investigate since my ENV includes Synplify Premier for synthesis and Quartus for P&R
Synplify Premier show me the clock definition correctly but the production files for Quartus include constraint with
more than 1 source objects.
Maybe I should check it with Synplify support team.

Hi,
I'm not sure if you can consider editing the constraints yourself, but it sounds like the constraint is targeting more than one source. Here are some examples for create_generated_clock:
