Executive Summary

Higher level of resource integration and the addition of new features in modern multi-processors put a significant pressure on their verification. Although a large amount of resources and time are devoted to the verification phase of modern processors, many design bugs escape the verification process and slip into processors operating in the field. These design bugs often lead to lower quality products, lower customer satisfaction, diminishing brand/company reputation, or even expensive product recalls. This paper proposes a flexible, low-overhead mechanism to detect the occurrence of design bugs during on-line operation.
