trd1(max) = (–trd)+ (tskew3 + tskew4)
t1(min) = time_1 * T – (tskew1 + tskew2 + tskew5)
t2(min) = time_2r * T – (tskew1 + tskew2 + tskew5)
t9(min) = time_9 * T – (tskew1 + tskew2 + tskew6)
t5(min) = tco + tsu + tbuf + tbuf+ tcable1 + tcable2

tA(min) = (1.5 + time_ax) * T – (tco + tsui + tcable2 + tcable2 + 2*tbuf)
trd1(min) = (time_pio_rdx – 0.5)*T – (tsu + thi)
(time_pio_rdx – 0.5) * T > tsu + thi + tskew3 + tskew4
t0(min) = (time_1 + time_2r+ time_9) * T
