How to use report_clock_timing ?

Hi,

Are there anyone able to briefly explain this command, report_clock_timing? And, how to explain the content of the report?
For example,
Maximum setup launch latency
Minimum setup capture latency
Maximum hold launch latency
Minimum hold launch latency
Maximum active transition
Minimum active transition
Maximum setup skew
Maximum hold skew

I wonder if the meaning below is correct or not.

Maximum setup launch latency means the maximum clock latency at launch register during setup check?
Minimum setup capture latency means the minimum clock latency at capture register during setup check?
Maximum hold launch latency means the maximum clock latency at launch register during hold check?
Minimum hold launch latency means the minimum clock latency at capture register during hold check?
Maximum active transition means Maximum transition at 0 to 1 ?
Minimum active transition means Minimum transition at 0 to 1 ?
Maximum setup skew means maximum clock skew during setup check ?
Maximum hold skew means maximum clock skew during hold check?

Thanks.



Peter
