US 7,689,952 B2 · System and method for determining and visualizing tradeoffs between yield and performance in electrical circuit designs

Abstract

A system that includes a candidate generator that generates candidate vectors having as components performance specifications of an electrical circuit design. The system also includes a performance estimator that generates performance vectors of the electrical circuit design, the performance vectors having as components performance values of the electrical circuit design. The candidate vectors and the performance vectors are input into a statistical estimator that calculates a statistical parameter, for example, yield, for each candidate vector in accordance with the performance vectors. The system further includes a filter that receives the candidate vectors and their respective statistical parameters, and outputs a filtered candidate vector with its corresponding filtered statistical parameter. A display system visually represents the filtered candidate vector and its corresponding filtered statistical parameter.
