Description

General Description:

When running timing analysis, the user gets the following: FATAL_ERROR:Timing:bastwprcntl.c:1922:1.27 - There

is no PERIOD constraint for the OFFSET constraint

TIMEGRP "OPADS" OFFSET = OUT 25 nS BEFORE

COMP "CLK" ; . Process will terminate.

Also See (Xilinx Solution 5489)

Solution

This should not be a fatal error, but to get around this, please

add a PERIOD constraint to the design.

This issue will be addressed in a future release.
