Table 4.1: Transition propagation rate for different gates. The rising and the falling

transitions do not enforce the same delay rates.

the gates deviate from their nominal values, i.e. [49],

d_r(g_i) = d^aomm⅛) + ξ_rtgilg_i,                  (4.4)

where          (grɪ ) is the nominal delay for rising transition and l_gi is the varia-

tion for the gate g_i and ξ_rι3i is a constant coefficient. Table 4.1 shows the constant
coefficients for NAND2 gate. Similarly for the falling transition,

dʃ(^) = dy^0mmal(<7j) + ξ_f,g_ilg_i.                     (4.5)

Thus, Equation 4.3 becomes
