# Test SDF reading with edge specifiers on timing checks (posedge/negedge
# on data), SETUPHOLD, RECREM, SKEW timing checks, and comprehensive
# annotation + write options.
# Targets:
#   SdfReader.cc: timingCheck with edge specifiers on data signals,
#     timingCheckSetupHold, timingCheckRecRem,
#     timingCheck for SKEW role, annotateCheckEdges with edge data,
#     setEdgeArcDelays for posedge/negedge on clock pins,
#     makePortSpec with edge, makeTriple, makeTripleSeq,
#     iopath, setCell, setInstance, cellFinish,
#     interconnect, port, findWireEdge, setEdgeDelays
#   SdfWriter.cc: writeTimingChecks, writeCheck with edge data
