W. Kruiskamp et D. Leenaerts, BEHAVIORAL AND MACRO MODELING USING PIECEWISE-LINEAR TECHNIQUES, Analog integrated circuits and signal processing, 10(1-2), 1996, pp. 67-76
In this paper we will demonstrate that most digital, analog as well as
behavioral components can be described using piecewise linear approxi
mations of their real behavior. This leads to several advantages from
the viewpoint of simulation. We will also give a method to store the r
esulting linear segments in a compact way, in order to avoid storage p
roblems.
