[Clock Domain] Tracing a signal

Question

Hi All,

Is there an easy way to trace/report, what clock drives a specific cell?

Please consider two cases:
1) the reported/traced cell is FlipFlop - this should be an easier way since the clock pin of the FlipFlop should be directly connected to the source/driving clock
2) the reported/traced cell is a leaf cell (e.g. OR or AND cell) - how can I report the clock domains of all the signals, which drive the reported/traced leaf cell?
Thank you!

You can also use the Timing Analyzer to cross-probe any path to the Chip Planner to see the path as it's routed in the device.

Hello,

You can use the netlist viewer to see the signals in your design.

Could you please explain more? Is there some video or tutorial, which explains how to check what clock domain the given signal belongs to?
Is there a TCL command or procedure, which could help in this case?

Thanks!
