Hello everyone,

I am doing the timing analysis of Ethernet MAC RGMII interface. But confused
to calculate the setup margin and hold margin. In the timing specification
of driver, its not clearly mentioned about the setup and hold time/ Please
guide me on how to calculate the setup and hold time for the given timing
specification.

TskewT -> -500ps to +500ps
TskewR -> 1ns to 2.6ns
Tclk   -> 7.2ns to 8.8ns... Typ 8ns
Tr/Tf  -> 0.75ns Max

Thanking you in advance,
Shrishail
