tm(min) = ti(min) = time_m * T – (tskew1 + tskew2 + tskew5)
td1(min) = td(min) = time_d * T – (tskew1 + tskew2 + tskew6)
tk(min) = time_k * T – (tskew1 + tskew2 + tskew6)
t0(min) = (time_d + time_k) * T
tgr(min-read) = tco + tsu + tbuf + tbuf + tcable1 + tcable2
tgr(min-drive) = td – te(drive)
tfr(min) = 5 ns
tg(min-write) = time_d * T – (tskew1 + tskew2 + tskew5)
tf(min-write) = time_k * T – (tskew1 + tskew2 + tskew6)
tL (max) = (time_d + time_k – 2)
