SHF: Small: Enabling Resiliency in Nanometer-Scale CMOS Circuits

现代集成电路设计涉及数十亿晶体管的cmos电路，使用微小的纳米级晶体管和导线建造。由于工艺不确定性、电源电压下降、温度变化和老化现象，这些技术受到重大变化的困扰，预计所有这些都将在未来几年变得更加关键。随着变化性不断侵蚀设计利润率和产量，当前的主流方法在未来将是不可持续的，新的方法将是必要的。可以通过在制造前的预硅阶段以及制造后的硅后阶段的设计优化来减少这种差异。这项工作的重点是在硅前阶段建立适应性设计技术，使硅后调整能够使电路从变化效应中恢复。将采取的方法将寻求将形式主义注入为设计具有复原力的系统建立一个实用框架的过程中。一个关键因素是开发新的传感器，并将它们纳入能够提供运行时适应的方案，该方案基于形成反馈环路的感知/缓解策略，并？治愈？A？病了？去死吧。这项研究的解决方案将促进针对计算和通信应用的下一代集成系统的设计，并有可能影响消费、计算和医疗保健领域的应用。该项目开发的技术将通过研究讨论和出版物转移到工业中。主要成果将通过皮？S研究网页发布。该项目将积极招募代表人数不足的少数群体参加研究项目，并将通过开发新的课程材料促进教育。

Modern integrated circuit design involves multibillion-transistor CMOS circuits, built using miniscule nanometer-scale transistors and wires. Such technologies are plagued by significant variations due to process uncertainties, supply voltage degradation, temperature changes, and aging phenomena, all of which are projected to grow more critical in the coming years. With variability steadily eating into design margins and yield, mainstream current-day methodologies will be unsustainable in the future and new approaches will be necessary. Such variations can be reduced by design optimization at the presilicon stage, before manufacturing, as well as at the postsilicon stage, after manufacturing. The focus of this work is to build design-for-adaptability techniques at the presilicon stage that enable postsilicon adjustments that allow circuits to recover from variational effects. The methods to be pursued will seek to inject formalism into the process of building a practical framework for designing resilient systems. A key ingredient is the development of new sensors and incorporates them into schemes that are capable of providing runtime adaptation, based on a sensing/mitigation strategy that forms a feedback loop, and ?cures? a ?sick? die. Solutions from this research will facilitate the design of next-generation integrated systems for computing and communication applications, and has the potential to impact applications in the consumer, computing, and healthcare spaces. The technology developed in this project will be transferred to industry through research discussions as well as publications. The key accomplishments will be distributed through the PI?s research webpage. The project will actively recruit underrepresented minorities to the research project, and will contribute to education through the development of new course materials.
