Problem Title:
PPR 5.0: Getting report of timespec failed paths BEFORE routing phase


Problem Description:



Solution 1:




By adding the following lines to an xactinit.dat file, PPR will
be forced to report which timespec paths will be missed before
it tries to route them:

pa_show_details=true		## give details even when specs are met
pa_pins_to_show=15		## show 15 worst endpoints (default = 3)
pa_paths_to_show=15		## show full details of 15 pins (default = 1)


To get detailed reporting of paths that missed their spec, add this
addition line:

/ppr/report_paths=true	 	## give details when specs are missed (only
				   at the end of routing
