M1.3.7 TRCE - Doing a TIG in the UCF file on a signal which is the
output of a tristate buffer does not work.



Problem Description:
Doing a TIG in the .UCF file on a signal or signals which is the output of a tri
state buffer does not work. The TIG is ignored and the signal will show up in th
e .TWR report. The only workaround is to put each signal that you wanted ignored
, into the .PCF file, which will work in not doing any timing analysis on the sp
ecified paths.
