Abstract
In this paper, we present a hierarchical approach for constraint transformation. The important features of this are: a genetic algorithm (GA) based search engine that computes design parameter ranges, a hierarchically organized characterization mechanism based on the concept of directed intervals that assists the search engine and an analog performance estimator. Experiments were conducted comparing the hierarchical approach with a flat bottom-up one. The results obtained demonstrate the effectiveness of the former approach. Experimental results highlighting the impact of using the characterization information within the constraint transformation process are also presented. 1. Introduction and Motivation Crucial to a top--down mixed--signal design process [12] is a mechanism to propagate the specifications and constraints on the design elements used at one level to those at the next level. This task of transforming the system-level specifications onto component level constraints is c...
