I find in the Board Skew Parameter Tool :
- the max deviation between byte-groups is 1 ns (according to me it's + or - 158 mm).

Yes! In the screenshot - second box from top notes this. I just stuck some values there to get this screenshot in the tool. The values in the green/orange boxes are not accurate at all. But you can see the min/max allowable values next to the boxes.

- the max deviation between byte-groups and clock is 0ps?!!? (I think that's mean that byte-groups track have to be shorter than clocks track.)
Is that correct ?

In the screenshot 0ps is indicated as min value. i.e. tpd-clk > tpd-dqs.
