This report should explain what's missing. Also, for the LVDS signal, I think the IP has generated SDC constraints so it doesn't appear as unconstrained input port. 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.
