Electromagnetic simulation is used in designing and analyzing systems ranging from integrated circuits to aircraft. This project is particularly interested in the use of electromagnetic simulation to support electromagnetic compatibility, EMC, studies (the way systems interact through the coupling of fields and on transmission lines) and signal integrity and power integrity, SIPI, (affecting the quality of digital signals usually in printed circuit boards or integrated circuit systems). Such simulation has a vast array of purposes, for example, it will look to identify whether one part of the system will cause interference with another part of the system, that electronic signals actually behave in the way that the designers want or to understand what happens if lightning strikes an aircraft in flight. In order to do any of these things, those relying on the results must be confident in the output of the simulations. This might be confidence in the solver but more often confidence in the implementation. Properly written simulation tools will always give the right answer to the question they have been asked; but the important thing is have they been asked the right question. This development of confidence in the tools and implementation involves validation and verification. There are limited methods and algorithms in common use, to provide quantitative support in that validation process, with subjective approaches such as 'eyeballing' graphs still being widespread. One approach that has been most widely used in EMC is the Feature Selective Validation (FSV) technique, developed by the PI and his co-workers. As the quality of software improves, the performance of the computing power increases and the demands on data-rich analysis evolve, it is important that FSV is enhanced to adapt to those changes and anticipate the needs of the community in the coming years. This travel grant provides support to document those needs with industries that themselves challenge the simulation developers for enhancements. This information will be combined with information from complementary companies in the UK to produce a roadmap for developments in FSV, along with generating other possible outputs addressing immediate issues. This roadmap will be used to guide the research of the PI but also provide a starting point for other research and industry groups to build a validation tool suitable for emerging needs in EMC and SIPI electromagnetic simulation.

电磁仿真用于设计和分析从集成电路到飞机的各种系统。该项目特别感兴趣的是使用电磁仿真来支持电磁兼容性、EMC、研究（系统通过场耦合和传输线路进行交互的方式）以及信号完整性和电源完整性、SIPI（通常影响印刷电路板或集成电路系统中的数字信号的质量）。这种模拟具有多种目的，例如，它将确定系统的一个部分是否会对系统的另一部分造成干扰，电子信号实际上按照设计者想要的方式运行，或者了解如果闪电击中飞行中的飞机会发生什么。为了完成这些任务，那些依赖结果的人必须对模拟的输出充满信心。这可能是对求解器的信心，但更常见的是对实现的信心。正确编写的模拟工具总是能够对所提出的问题给出正确的答案；但重要的是他们是否被问到了正确的问题。对工具和实施的信心的发展涉及验证和验证。在验证过程中提供定量支持的常用方法和算法有限，“目测”图等主观方法仍然很普遍。 EMC 最广泛使用的一种方法是特征选择性验证 (FSV) 技术，由 PI 及其同事开发。随着软件质量的提高、计算能力性能的提高以及对丰富数据分析的需求的发展，增强 FSV 以适应这些变化并预测未来几年社区的需求非常重要。这笔差旅补助金提供支持来记录行业的这些需求，这些行业本身也对模拟开发人员提出了增强要求。这些信息将与英国互补公司的信息相结合，制定 FSV 发展路线图，并产生解决眼前问题的其他可能的成果。该路线图将用于指导 PI 的研究，同时也为其他研究和行业团体提供一个起点，以构建适合 EMC 和 SIPI 电磁仿真新兴需求的验证工具。
