Speed-limiting paths are critical paths that limit the performance of one or more silicon chips. This paper present a data mining methodology for analyzing speed-limiting paths extracted from AC delay test measurements. Based on data collected on 15 packaged silicon units of a four-core microprocessor design, we show that the proposed methodology can efficiently discovered actionable, design-related...
This paper studies the problem of automatic assertion extraction at the input boundary of a given unit embedded in a system. This paper proposes a data mining approach that analyzes simulation traces to extract the assertions. We borrow two key concepts from the sequential data mining and develop an effective assertion extraction approach specific to our problem. These two concepts are (1) the slide-window-based...
In this paper, we propose a method for extracting the spectral information of a multigigahertz jittery signal without using an ideal reference clock. This method utilizes existing on-chip single-shot period measurement techniques to measure single periods of a multigigahertz signal for analysis. Utilizing the same sampling and measuring principle, we propose another less computationally intensive...
