TMC-20022: I/O Delay Assignment Missing Parameters


Violations of this rule identify ports with I/O delay assignments that don't have specifications for -reference_pin and -source_latency_included when the -clock specified is an internally targeted clock (not assigned to an input or output port).


Specify the missing options for the delay assignment or specify a clock source that is assigned to a top level input or output port. If the clock is a virtual clock, specify the source latency of the virtual clock.
