15 years ago --- Quote Start --- I'm trying to figure out my RSKM by using TQ and the rskm_report command. So I suppose that if TQ won't report it, then I have use the Tsu and Thld times reported by TQ to calculate the RSKM. RSKM = (TUI - SW - TCCS)/2 TUI : Time Unit Interval SW : Sampling Window TCCS: Transmitter channel to channel skew Tsw = Tsu + Thd + PLL jitter --- Quote End --- Well, if that is the relevant equation then it should work out correctly if you have correct tSU/tH at the input pins. The tSU/tH will be correct if you have entered tCO of external device for set_input_delay's (+effect of board delays).
