Introduction

Stephen A. Cannon is a notable inventor based in Fremont, CA. He has made significant contributions to the field of semiconductor testing and analysis. With a total of 2 patents, his work focuses on improving the reliability and efficiency of scan chains in digital circuits.

Latest Patents

Cannon's latest patents include methods for analyzing scan chains and determining the numbers or locations of hold time faults in these chains. One of his methods involves setting an environmental variable of the scan chain to a value believed to cause a hold time fault. A pattern is then shifted through the scan chain, which helps in determining the number of possible hold time faults. This is achieved by analyzing the difference between the expected and actual clock cycles that cause transitions at the output of the scan chain. Another patent focuses on locating hold time violations in scan chains by generating patterns on automated test equipment (ATE). This method counts potential defects and aims to localize and ameliorate hold time defects in a scan chain.
