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-drive) = 0
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)*T – (tsu + tco + 2*tbuf + 2*tcable2)
tn= tj= tkjn = (max(time_k,. time_jn) * T – (tskew1 + tskew2 + tskew6)
ton = time_on * T – tskew1
toff = time_off * T – tskew1
