How do i quick rise / back rise?

[CHAO$$$]

it used to be back back or down down in sf5 but i cant seem to get it to work here. I cant find any help for this information either

hold two punch (or two kick) buttons together to back rise. You don't have to do it with any specific timing - if you get hit and can already see you will get knocked down, press and hold the buttons and the character will roll back as soon as they can.

As for quick rising, there is no such thing in SF6.
