I have an input that goes from one input driver to 4 IDELAYE2 and I would like to have the same delay on each line. This I think this is what we call skew? Why there is a skew value for each end point. Is this the variation due to temperature?
I was expected to have just one value.
From To Delay(ns)Skew(ns)
B11.I SLICE_X43Y137.AX 1.689 0.418
B11.I SLICE_X42Y135.AX 1.724 0.453
B11.I SLICE_X42Y136.AX1.645 0.374

There is no such thing as exactly matching anything at all. Devices vary in strength, wires vary in resistancwe, length, etc.
Add voltage and temperature, and everything together will change, too.
