Abstract :
Texas Instruments ASIC Division (TI) has developed a highly accurate and flexible statistical characterization technique using equations to predict delay performance. A 21-term polynomial equation is described which accurately predicts individual cell delays as a nonlinear function of supply voltage, temperature, process variation, input slew time (rise and fall time), and output loading. The accuracy and flexibility of this technique is contrasted with traditional, less sophisticated methods
