INFO:Timing:2752 - To get complete path coverage, use the unconstrained paths option. All paths that are not constrained will be reported in the unconstrained paths section(s) of the report. INFO:Timing:3339 - The clock-to-out numbers in this timing report are based on a 50 Ohm transmission line loading model. For the details of this model, and for more information on accounting for different loading conditions, please see the device datasheet.
