INFO:Timing:2698 - No timing constraints found, doing default enumeration.
INFO:Timing:3412 - To improve timing, see the Timing Closure User Guide (UG612).
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.
INFO:Timing:3390 - This architecture does not support a default System Jitter
value, please add SYSTEM_JITTER constraint to the UCF to modify the Clock
Uncertainty calculation.
INFO:Timing:3389 - This architecture does not support 'Discrete Jitter' and
'Phase Error' calculations, these terms will be zero in the Clock
Uncertainty calculation. Please make appropriate modification to
SYSTEM_JITTER to account for the unsupported Discrete Jitter and Phase
Error.
