A user defined generated clock is:
- Defined by the
create_generated_clockcommand. - 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.
