t1
t1 (min) = time_1 * T – (tskew1 + tskew2 + tskew5)
time_1
t2
t2w
t2 (min) = time_2w * T – (tskew1 + tskew2 + tskew5)
time_2w
t9
t9 (min) = time_9 * T – (tskew1 + tskew2 + tskew6)
time_9
t3
t3 (min) = (time_2w – time_on)* T – (tskew1 + tskew2 +tskew5)
If not met, increase
time_2w
t4
t4 (min) = time_4 * T – tskew1
time_4
tA
tA = (1.5 + time_ax) * T – (tco + tsui + tcable2 + tcable2 + 2*tbuf)
