在LTspice®原理图中，有多种方法可模拟随机性。LTspice中的flat ()、gauss ()和mc ()函数支持在LTspice仿真中引入随机性。本文以mc ()函数为例，说明如何模拟无源元件值的容差。打开LTspice后，选择Help > LTspice Help（“帮助”>“LTspice帮助”，或按F1）可打开《帮助手册》，了解有关flat ()和gauss ()的更多信息。

Not all Spice versions perform Monte Carlo simulations. Even those that do may only have a small number of available distributions, much less custom ones. LTSpice, for example, has built-in random ...

This article describes how LTspice simulations can be used to account for the effect of voltage dependence, or dc bias, caused by the use of ceramic capacitors with smaller and smaller case sizes.
