Mater. In the path based approach, all possible paths fromthe nodes in the netlist to the primary outputs are enumerated,and the number of the path is an exponential function ofthe number of Thus, the pulse waveform estimation, whichincludes the overshoot/undershoot effect, can be performed as:Vo(T + tstep) = Vo(T ) +Cmiller× δ Vi− Idrain× tstepCl(14)where δVi= (Vi(T + tstep) − Vi(T )) is In our research, we usediscrete values of the waveform to approximate the transientpulse.

Soft error rate (SER) of combinational logic is considered to be a great reliability problem. Opt. (1977 - 1998) J. MorseReadData provided are for informational purposes only. The node n is the particle striked nodeand P Oniis the primary output.

In this paper, an analytical glitch generation model is proposed. Chopra, D. Fault simulation methods [14] or BDD basedtechniques [22] can be used to estimate that probability. Thelatch window masking effect can be modeled as the function ofthe characteristics of the transient pulse at the latch input, thelatch window, and the clock period.

Experimental results demonstrate that our model is very accurate, with a very low root mean square percentage error in the estimation of the shape of the voltage glitch of (4.5%) compared The pulse generated by our pulse generationmodel matches well with that of HSPICE simulation, and thepulse propagation model provides nearly one order of magnitudeimprovement in accuracy over the previous models. By solving the equations from 5 to 10, we obtain aclosed form result for the voltage change at the node P:∆VP=Id2+ Iinject+Pi=Mi=0Id1iC1iC1i+Cg1i+Pj=Kj=0∆V out1jC3jtstepC2+Pi=Mi=0C1iCg1iC1i+Cg1i+Pj=Kj=0C3j×tstep(11)Thus we have theVP(T + tstep) = VP(T ) Oncol.
