Since physical radiation experiments are di cult and expensive,

the e ects of radiation on a given circuit are commonly studied by Spice sim-

ulations. Injecting a current pulse with double exponential shape has become

the method of choice for emulating a radiation particle hit, and the charge of

this pulse is considered characteristic for the deposited particle energy. The

double exponential model, however, has three degrees of freedom, namely rise

time, fall time and peak current, and there is no clear agreement in the lit-

erature on their actual choice. In this paper we investigate the impact of this

choice on the simulation results. To this end we study the charge required to

ip the state of a Muller C-element, while varying rise and fall time. It turns

out that this charge indeed depends on the chosen time values, which invali-

dates the belief that charge is the only relevant characteristic. The conclusion

is that simulation studies should use various choices for the parameters and

apply statistics to cover all scenarios encountered in the real world { choosing

a single "representative" parameter set is not su cient.
