Abstract

Less predictable path delays and many paths with delays close to the clock period are the main trends affecting the delay testability of deep-submicron designs. This article examines the challenges in meeting the quality requirements of gigascale integration, and explores functional testing as well as statistical models and methods that could alleviate some of those problems.
