GOALI (Industry-University Collaborative Project): Collaborative Research: Scalable Techniques for Detecting Small-Delay Defects in Nanometer Integrated Circuits

该项目的目标是开发针对纳米级集成电路中小延迟缺陷的新测试技术。 该方法是基于使用的输出偏差测量作为一个替代的“长路径”的覆盖度量小延迟的缺陷。 该项目将与AMD公司和其他工业合作伙伴合作开展。智力优势：由工艺变化、串扰、电源噪声和电阻开路/短路等引起的小延迟缺陷，是半导体工业中主要的质量和可靠性问题。 目前的行业实践不仅不足以解决小延迟缺陷，而且测试成本也在飙升（估计超过制造成本的50%）。 该项目的重点是使用可扩展的方法生成测试，可以为工业电路提供全面的缺陷筛选。 它包括以下组成部分：（一）门延迟缺陷概率测量模型延迟故障;（二）使用门延迟缺陷概率计算输出偏差;（三）布局感知，偏差为基础的测试模式选择/生成高缺陷covery.Broader影响：该项目将导致更高的出货产品质量，增加现场的可靠性，并降低测试成本。 为社会带来的好处包括用于医疗保健的可靠电子产品，用于服务器、天气预报、金融交易等的更便宜、更可靠的计算平台，以及实现汽车应用中备受追捧的零缺陷。学生将通过研究经验，课程和相关行业实习培训劳动力。将作出协调一致的努力，让代表性不足的群体参与进来，例如通过半导体研究公司的奖学金计划。 将在主要会议上提出报告并组织特别会议。

ObjectiveThe objective of this project is to develop new test techniques that target small-delay defects in nanoscale integrated circuits. The approach is based on the use of the output-deviations measure as a surrogate "long-path" coverage metric for small-delay defects. The project will be carried out in partnership with AMD Corporation and other industrial collaborators. Intellectual Merit: Small-delay defects, induced by process variations, crosstalk, power-supply noise, and resistive opens/shorts, etc., are major quality and reliability concerns in the semiconductor industry. Current industry practices are not only inadequate for small-delay defects, but test costs are skyrocketing as well (estimated to be more than 50% of manufacturing cost). This project is focused on test generation using scalable methods that can provide comprehensive defect screening for industrial circuits. It includes the following components: (i) a gate-delay-defect probability measure to model delay faults; (ii) use of gate-delay-defect probabilities for computing output deviations; (iii) layout-aware, deviation-based test-pattern selection/generation for high defect coverage.Broader Impacts: This project will lead to higher shipped-product quality, increased in-field reliability, and reduced test cost. Benefits for society include reliable electronics for healthcare, cheaper and dependable computing platforms for servers, weather forecasting, financial transactions, and more, and realization of the much sought-after zero-defects for automotive applications. Students will be trained for the workforce through research experience, coursework, and relevant industry internships. A concerted effort will be made to involve under-represented groups, for example through the Semiconductor Research Corporation fellowship programs. Tutorials will be presented and special sessions will be organized at major conferences.
