Abstract :
This paper describes a method for estimating Soft Error Rate (SER) and a systematic approach to identifying SER solutions. Having a good SER estimate is the first step in identifying if a problem exists and what measures are necessary to solve the problem. In this paper, a high performance processor is used as the base framework for discussion since it contains most, if not all, commonly used micro-architecture and circuit techniques associated with any state-of-the-art design. The framework provides a guideline for users to follow and to apply appropriate judgment to their particular problem. One major finding in this paper is that latches/flip-flops and combinational logic contribute significantly to the overall chip Failure-In-Time (FIT) rate. We also discuss potential SER techniques to combat this revelation.
