how to calculate the board clock skew

hi, I try to calculate delay value for set_input_delay constraint using the rule below: input delay (max) = Board Delay (max) - Board clock skew (min) + Tco(max) = Tdata_PCB(max) + Tco(max)...

hi, rysc, i know that the clock skew can not be avoided completely and as you said, that's what it's showing. but how can i get this value(+/- 0.5ns in the example)? by ondoscope or something else (tool or formula)?:oops:

the way ashishkaps provided seems to be a good method to workaround?;)

thanks!
