项目摘要

Power management circuits and systems generally regulate voltage and current under battery drain, provide power conversion to various electronic loads for optimizing system efficiency, and provide low-noise supplies to sensitive circuits. At present, these systems are optimized through custom architecture selection and design optimization by an experienced team -- a process that is not conducive to the low-cost, fast-paced development cycles required for market deployment in consumer applications, e.g., IoT devices, wearables, and automotive. This project aims to develop a design flow that minimizes the number of complex steps requiring human oversight, substantially reduces product development cycle time and cost, and maximizes power-converter performance by considering performance variation/degradation over lifetime. The automation platform developed through this award will allow a small number of engineers to design and optimize these systems, enabling designers to spend more time on developing novel converter architectures and exploring the design space for new circuit topologies. The educational activities involve integrating design automation for integrated electronics with of student training from academic stages from K-12 through college level. The findings of the project will be incorporated into two courses at Arizona State University.This project will advocate a novel paradigm for automating design of analog systems, in particular power electronics. Integrated built-in-self-test will be used to monitor power system performance and update statistical models used during the design phase, thus increasing the occurrences of first-pass design success. The design automation of these closed-loop systems will be achieved through: a) creation of analytical models to express the numerous power converter architectures, b) development of a circuit component design library, c) a circuit simulation methodology for collecting a representative subset of design parameters that will correlate to the relevant performance space, d) creation of statistical models and data that can be used to fit to geometric programming (GP) and support vector machine (SVM) algorithms, and e) development of a computationally efficient and accurate optimization approach. The automation methods generated from this research effort, including the methodology for creating statistical models and collecting empirical data, the generated circuit component design library, and the algorithms for optimizing a closed-loop power converter system with hierarchical circuits may be used for design of other closed-loop or complex analog systems, such as phase-locked loops (PLLs) and sensors.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

电源管理电路和系统通常在电池消耗情况下调节电压和电流，为各种电子负载提供电源转换以优化系统效率，并为敏感电路提供低噪声电源。目前，这些系统是通过经验丰富的团队进行定制架构选择和设计优化来进行优化的，这一过程不利于消费者应用（例如物联网设备）市场部署所需的低成本、快节奏的开发周期。可穿戴设备和汽车。该项目旨在开发一种设计流程，最大限度地减少需要人工监督的复杂步骤的数量，大幅减少产品开发周期时间和成本，并通过考虑生命周期内的性能变化/退化来最大限度地提高电源转换器的性能。通过该奖项开发的自动化平台将允许少数工程师设计和优化这些系统，使设计人员能够花更多的时间来开发新颖的转换器架构并探索新电路拓扑的设计空间。教育活动涉及将集成电子设计自动化与从 K-12 学术阶段到大学水平的学生培训相结合。该项目的研究结果将被纳入亚利桑那州立大学的两门课程中。该项目将倡导模拟系统（特别是电力电子系统）自动化设计的新颖范式。集成的内置自测试将用于监控电力系统性能并更新设计阶段使用的统计模型，从而增加一次性设计成功的几率。这些闭环系统的设计自动化将通过以下方式实现：a）创建分析模型来表达众多电源转换器架构，b）开发电路元件设计库，c）用于收集代表性子集的电路仿真方法。设计与相关性能空间相关的参数，d) 创建可用于适应几何规划 (GP) 和支持向量机 (SVM) 算法的统计模型和数据，以及 e) 开发计算高效且准确的模型优化方法。这项研究工作产生的自动化方法，包括创建统计模型和收集经验数据的方法、生成的电路元件设计库以及优化具有分层电路的闭环功率转换器系统的算法，可用于其他设计闭环或复杂的模拟系统，例如锁相环 (PLL) 和传感器。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
