A1.4/F1.4 Map - FATAL_ERROR:baste:bastetspec.c:908:1.69 - No pins of NC_SIGNAL ...


An environment variable (XIL_MAP_TOLERATE_TIG_ERROR) has been
added that changes certain timespec related fatal errors to
warnings. The errors ocurr when the correlation between the logical timespec constraint and the physical implementation is lost during mapping. Use of the environment variable caused
the timespec to be lost, but allows map to continue. Many
of these cases have to do with lost TIGs, so the impact of
the lost timespec is that a path is over constrained.
