ID:332087 The master clock for this clock assignment could not be derived. Clock: <Clock Name> was not created.

CAUSE: The Timing Analyzer could not derive the master_clock of this generated clock. There are three possible causes for this error: the -master_clock option is used, but no clock by this name is found on the fanin of the -source option; no clocks are found on the fanin of the -source option and the -master_clock option is not used; multiple clocks are found on the fanin of the -source option and the -master_clock option is not used.

ACTION: Use the -master_clock option to specify a valid clock that exists on the fanin of the specified -source node.
