PILA: a computer program for fast and accurate analysis of piecewise linear circuits

The computer program PILA, which is designed for the fast and accurate analysis of moderately-sized piecewise-linear circuits, is described. Since PILA does not use numerical integration, it is particularly useful for exploring the qualitative behavior of circuits with complicated time evolutions, e.g. in the presence of chaotic solutions. The computational accuracy and the capability to deal with linearly dependent capacitor charges and inductor fluxes are highlighted with two examples.<<ETX>>
