Method for Automated Worst Case Circuit Design and Analysis

Historically, worst case circuit analysis (WCCA) has been applied primarily in industries requiring very high reliability (e.g., telecommunications, defense and aerospace). Unfortunately, the techniques for WCCA have been relatively difficult to perform and involve time-consuming iterative and statistical processes [1, 2, 3]. High reliability is now required in automotive applications.

This paper describes a patented [4], non-iterative, automated worst case circuit design and analysis (WCCDA) method that is practical for budget and time limited projects. Reliable circuit performance over extreme operating temperature ranges (e.g., from −65°C to 125°C) is achieved. Circuits are designed and analyzed in less than two minutes, and no special tools are required.
