使用脉冲激光器来证明，对于比时钟时间短得多的瞬态，顺序逻辑中的错误率独立于频率，而组合逻辑中的错误率是线性依赖于频率的。另外，通过测量固定crock频率的激光脉冲能量的函数，建立了Compinational逻辑中时钟边缘之前的SEU脆弱时间段的对数依赖性。混合模式电路模拟器程序用于成功地对逻辑电路对激光脉冲的动态响应进行建模。
A pulsed laser was used to demonstrate that, for transients much shorter than the clock period, error rates in sequential logic were independent of frequency, whereas error rates in combinational logic were linearly dependent on frequency. In addition, by measuring the error rate as a function of laser pulse energy for fixed crock frequency, the logarithmic dependence of the SEU vulnerable time period prior to the clock edge in combinational logic was established. A mixed mode circuit simulator program was used to successfully model the dynamic response of the logic circuit to pulses of laser light.
