WebThe clock period is defined in the tool to be 10 time units. The time unit size, such as ns or ps, is specified in the logic library. By default, the tool assumes that signals are propagated through each data path in one … Web` Ideal clocks – uses propagated clocks by default, however, it also allows the use of ideal clocks where latency and transition times for the clock signals in a clock network may be directly annotated instead of computed ` Generated clocks – supports the use of clocks derived from a master clock.
