OpenSTA/sdf/test/sdf_write_interconnect.tcl

# Test SDF write with interconnect delays from SPEF, various write options,
# and large design coverage.
# Targets: SdfWriter.cc (writeInterconnects, writeInstInterconnects,
#   writeInterconnectFromPin, writeArcDelays, writeSdfTriple,
#   writeSdfDelay, sdfPortName, sdfPathName, sdfName, sdfEdge,
#   writeWidthCheck, writePeriodCheck, writeTimingChecks,
#   writeCheck variations, writeIopaths)
#   SdfReader.cc (re-read from written SDF)
#   ReportAnnotation.cc (annotation with interconnect data)
