14.x Timing Analyzer - "WARNING:Timing:3223 - Timing constraint "%s" ignored during timing analysis."

Description


The following warnings appear in the static timing report:
"WARNING:Timing:3223 - Timing constraint "%s" ignored during timing analysis."
"WARNING:Timing:3225 - Timing constraint %s ignored during timing analysis"

Solution


The constraint will be ignored if other constraints with higher priority override it or there is no element in the timegroup. The warning can also be caused by there being no synchronous data paths between the elements in the referenced timing group.
Suggestions:
A. Run a TSI (Time Spec Interaction) report to determine which constraints interacted with the constraint in question.

B. Confirm that the elements of the Time Groups are synchronous elements in FPGA Editor. Use the Query TimeGrps command from Timing Analyzer to produce a report of the elements of the Time Groups.
