t1 (min.) = time_1 * T – (tskew1 + tskew2 + tskew5)
t2 (min.) = time_2w * T – (tskew1 + tskew2 + tskew5)
t9 (min.) = time_9 * T – (tskew1 + tskew2 + tskew6)
t3 (min.) = (time_2w – time_on)* T – (tskew1 + tskew2 +tskew5)
t4 (min.) = time_4 * T – tskew1
tA = (1.5 + time_ax) * T – (tco + tsui + tcable2 + tcable2 + 2*tbuf)
t0(min.) = (time_1 + time_2 + time_9) * T
Avoid bus contention when switching buffer on by making ton long enough.
Avoid bus contention when switching buffer off by making toff long enough.
