Computer-aided high-frequency modeling and design

包括射频/微波和无线行业在内的高频电子行业的竞争力可以为我们的经济做出重大贡献。例如，加拿大的无线产业在2003年创造了82亿美元的收入，如今超过2.5万加拿大人在该行业工作。计算机辅助设计（CAD）领域的研究为高频电路的设计和优化提供了关键工具，这些电路在通信、消费电子和卫星链路中得到了应用。是什么让这些电路的CAD具有挑战性？工作在千兆赫兹频率的电子电路模拟全波电磁或EM行为。高频效应，例如电磁耦合，如果在CAD阶段不考虑，可能会导致设计修改和上市周期延长，从而造成重大的经济影响。所提出的研究旨在增强传统CAD工具及其面向低频的模型库。教授人工神经网络（ANN）学习EM行为，然后将EM-ANN模型优雅地集成到cad工具库中，将仍然是一个活跃的线程。具体而言，该提案侧重于开发使用自适应采样的经济高效高频建模工具，探索快速互连优化工具，制定代表片上无源之间EM耦合的灵活CAD模型，以及研究用于卫星滤波器设计的CAD工具。最直接的结果将是发明新的计算机辅助建模、设计和优化工具，供电路设计师和工业cad工具用户使用。这项工作有可能提高设计效率，缩短设计周期和上市时间，提高产品质量，降低消费者成本。这项研究培养的人才将成为我们行业的高技能劳动力。这些因素可能导致保持加拿大高频电子工业在全球市场上的竞争力。

The competitiveness of the high-frequency electronics industry including RF/microwave and wireless sectors can significantly contribute to our economy. For instance, Canada's wireless industry generated $8.2 billion in revenues in 2003, and today more than 25,000 Canadians work for the industry. Research in computer aided design (CAD) arena leads to key vehicles for design and optimization of high-frequency circuits, which find applications in communications, consumer electronics and satellite links. What makes CAD of these circuits challenging? Electronic circuits operating at Gigahertz frequencies emulate full-wave electromagnetic or EM behaviours. High-frequency effects, e.g. EM coupling, if not considered during the CAD phase, could lead to prolonged design-revision and time-to-market cycles thereby causing substantial economic fallouts. The proposed research is geared towards enhancing traditional CAD tools and their low-frequency oriented model libraries. Teaching artificial neural networks (ANN) to learn the EM behaviours, followed by elegant integration of EM-ANN models into the CAD-tool libraries will remain an active thread. Specifically, this proposal focuses on development of cost-effective high-frequency modeling tools using adaptive sampling, exploration of rapid interconnect optimization tools, formulation of flexible CAD models representing EM coupling between on-wafer passives, and investigation of CAD tools for design of filters used in satellites. The most direct outcome will be invention of novel computer aided modeling, design and optimization tools for circuit designers and CAD-tool users in industry. This work has a potential to increase design efficiency, shorten design cycles and time-to-market, enhance product quality, and decrease consumer costs. Personnel trained by this research will constitute highly skilled workforce for our industry. These factors could lead to maintaining the competitiveness of the Canadian high-frequency electronics industry in the global market.
