clock edge is defined as the length of time be-
tween when the signal exits and remains out of
the switching region and when the clock enters
the switching region. The hold time of an MII
signal relative to an MII clock edge is defined as
the length of time between when the clock exits
the switching region and when the signal enters
the switching region.
