时域离散的开关电容电路如何仿真

模拟IC设计中，一些开关电路中的电压电流输出量是需要获得平均值的，如何用tran分析仿真开关电路并获得这些需要的平均值。

I use hspice to output these node voltage to text file and calculate the average with matlab or python/perl

Then how to assure that the output results of these quantities are convergent since the existance of algrithm error? As a matter of fact, the form of output mean value should be like A/B,

where A is the integration of voltage or current to the respect of the time and B is the time region. Ripples at the transition point T1 are difficult for integration.
