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.
================================================================================
Timing constraint: TS_cp2 = PERIOD TIMEGRP "cp2" 8 ns HIGH 50%;
106838544 paths analyzed, 1535 endpoints analyzed, 170 failing endpoints
170 timing errors detected. (170 setup errors, 0 hold errors, 0 component switching limit errors)
Minimum period is 9.385ns.
