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
