WebIf a clock with a different name exists on the given target, the create_clock command will be ignored unless the -add option is used. The -add option can be used to assign multiple clocks to a pin or port. If the target of the clock is internal (i.e. not an input port), the source latency is zero by default. WebOptions Description for create_generated_clock Command. Option. Description. -name . Name of the generated clock, for example, clk_x2. If you do not specify the clock name, the clock name is the same as the first node to which it is assigned. … groovy wait seconds

WebJan 1, 2013 · A virtual clock has no source specified. In reality, it might have a source, but that source could be outside the block being constrained. Virtual clocks are modeled using the create_clock command with period, waveform, and name option only, but source object is missing. For example, create_clock -period 10 -name v_clk -waveform {0 5} WebSource latencies are based on clock network delays from the host clock (not necessarily the host pin). You can use the set_clock_latency -source command to override the source latency..
