# Test SDF reading with DEVICE delays, edge specifiers (posedge/negedge)
# on timing check data signals, SETUPHOLD, RECREM, NOCHANGE, SKEW,
# INCREMENT annotations, and various triple formats.
# Targets:
#   SdfReader.cc: device(SdfTripleSeq*), device(string*, SdfTripleSeq*),
#     setDevicePinDelays, timingCheck with edge specifiers on data,
#     timingCheckSetupHold, timingCheckRecRem, timingCheckNochange (notSupported),
#     timingCheck for skew role, setInIncremental, incremental annotation paths,
#     setEdgeArcDelays in_incremental_ path, makeTriple, makeTripleSeq
#   SdfWriter.cc: writeTimingChecks with edge specifiers
