Top-down, constraint driven design: application to sigma-delta modulator

Abstract

In order to reduce analog systems development time, in particular sampled ones, we propose in this article a design method based on behavioral modeling. The method uses a hierarchical "top-down" constraints driven approach. To calculate the design constraints, the "programming by flexible constraints CSPf" method is used. Validation of the approach is made on a sensor interface based on a delta sigma modulator.
