General Description: TRCE/Timing Analyzer does not report skew by default.
There are three ways for TRCE/Timing Analyzer to report clock skew.
1- Place a PERIOD constraint on the clock net. Clock skew is automatically reported with a PERIOD constraint.
2- Set the following environment variable:
XILINX_DOSKEWCHECK = 1
3- Run TRCE via the command line with the -skew option.
