# Test CCSN (current source) models and various timing model types.
# Targets:
#   LibertyReader.cc: beginCcs/endCcs, receiver_capacitance groups,
#     timing_type combinations,
#     beginOutputCurrentRise/Fall, visitReceiverCapacitance,
#     polynomial model visitors, ccsn noise model visitors,
#     leakage_power groups, internal_power groups,
#     max_capacitance/max_transition on pins, min_pulse_width
#   TableModel.cc: different table axis variables, GateTableModel,
#     CheckTableModel, 3D tables, receiver model tables
#   TimingArc.cc: timing arc type queries (removal, recovery,
#     three_state_enable, rising_edge, min_pulse_width)
#   Liberty.cc: timing arc set queries, hasTimingArcs, timingArcSets
