With technology scaling and increasing integration density in the nanometer technology regime, design considerations for yield and reliability have become critical. The objective of this collaborative research is to explore low-overhead formal design methodology with distributed micro-scale sensor network and systematic feedback control to achieve auto-curing of digital, analog and mixed-signal electronic systems under large process and temporal variations. Such auto-curing approaches will play a key role in preventing yield loss for nanoscale designs, while ensuring reliability of operation and low power dissipation. The research investigates self-curing concepts/techniques for logic circuits, digital signal processing (DSP) units, embedded memory and analog components using appropriate variation sensing and compensation techniques to achieve high yield with optimal power/die-area overhead. It also explores system-level self-curing approaches using global parameter sensor and global controller to determine optimal compensation of mixed-signal cores under power constraint. To realize the curing methodologies in an automatic synthesis environment, the research will aim at developing appropriate Computer-Aided Design tools and a library of self-correcting mixed-signal cores. If successful, it will help the semiconductor industry deliver complex nanoelectronic systems with high reliability, low power and high yield. The proposed research will integrate education and training through course development, summer research program for undergraduates, and senior project design.

随着纳米技术领域的技术缩放和集成密度的增加，成品率和可靠性的设计考虑已经变得至关重要。这项合作研究的目的是探索低开销的形式化设计方法与分布式微尺度传感器网络和系统的反馈控制，以实现自动固化的数字，模拟和混合信号的电子系统在大的过程和时间变化。这种自动固化方法将在防止纳米级设计的产量损失方面发挥关键作用，同时确保操作的可靠性和低功耗。该研究调查了逻辑电路，数字信号处理（DSP）单元，嵌入式存储器和模拟元件的自固化概念/技术，使用适当的变化检测和补偿技术，以实现最佳的功率/芯片面积开销的高产量。本文还探讨了系统级自修复方法，该方法使用全局参数传感器和全局控制器来确定功耗约束下混合信号核的最佳补偿。为了在自动综合环境中实现固化方法，本研究将致力于开发适当的计算机辅助设计工具和自校正混合信号内核库。如果成功，它将帮助半导体行业提供高可靠性，低功耗和高产量的复杂纳米电子系统。拟议的研究将通过课程开发，本科生暑期研究计划和高级项目设计来整合教育和培训。
