# Test SDF reading with edge specifiers, PORT delays, and write options.
# Targets: SdfReader.cc (edge specifiers, PORT delay, RECOVERY/REMOVAL/PERIOD)
#   SdfWriter.cc (write with various option combinations)
#   ReportAnnotation.cc (annotation reporting with multiple check types)
#   SdfParse.yy (edge specifier grammar paths, PORT DELAY)
