A user defined generated clock is:

  • Defined by the create_generated_clock command.
  • Attached to a netlist object, preferably the clock tree root pin.

Specify the master clock using the -source option. This indicates a pin or port in the design through which the master clock propagates. It is common to use the master clock source point or the input clock pin of generated clock source cell.

Important: The -source option accepts only a pin or port netlist object. It does not accept clock objects.
