WebWhen I turn on the "report unconstrained paths" in the Timing Analyzer, I see unconstrained paths from the clock input pad to the FFs: ===== Timing constraint: Unconstrained path … Web27 Apr 2014 · a. Is there any false path to these registers. b.Is there any disabled timing , which is masking the timing checks. c. you might have applied max_delay dealy and may be have syntax issues. All above that, set *unconstrained* variable to true in PT and check report_timing -exceptions all command will give better idea, why this path is unconstrained.

WebThe timing report is reporting the unconstrained path we discussed so far as going from the AXIS_CLOCK domain to some undefined clock domain (see rightmost columns of the attached screenshot). Looking at the device view and looking at the clock pins of each of the source and destination FF, I get the following: WebYou may observe Quartus® II software report unconstrained paths while running quartus_sta with the --sdc option to perform timing analysis.
