PT report_qor Script

#
# Procedure to emulate DC's report_qor in PT
#
# Version 1.10 6/1/09 pjarvis
#
# Revision history
# 1.0 (pfj) 9/3/03 - Initial release
# 1.1 (pfj) 9/4/03 - Added hold-time reporting
# 1.2 (pfj) 9/4/03 - Rewrote report_constraint parser and added all other DRCs
# 1.3 (pfj) 9/4/03 - Added missing DRCs and fixed a bunch of related problems
# 1.4 (pfj) 9/5/03 - Rewrote DRC parser to eliminate dependency on list of DRCs
# 1.5 (pfj) 9/30/03 - Fixed bug with unconstrained path slacks
# 1.6 (pfj) 5/14/04 - Changed report_constraint to use 5 digits for consistency with its DRC summary values
# 1.7 (pfj) 4/27/07 - Added DMSA support; switched to redirect -variable instead of using temp file;
#                     fixed bug with recovery/removal sum/count not being reported in async_default group;
#                     added -significant_digits switch and dummy -physical switch (compatibility with DC/ICC)
# 1.8 (pfj) 11/5/07 - Added code to stop script from running in 2007.06-* PrimeTime DMSA mode prior to 2007.06-SP3
#                     to avoid merged-reporting bug from STAR 9000188708
# 1.9 (pfj) 11/13/07 - Changed get_pins -of [get_cells $nonhier_cells] to the more-memory-efficient
#                      get_pins -hier * -filter "is_hierarchical==false" approach; reduces overall memory usage
# 1.10 (pfj) 6/1/09  - Fixed bug in DMSA mode where zero TNS and path count is reported with nonzero WNS;
#                      alphabetized display of path groups to avoid nondeterministic get_timing_paths group ordering
