Performance Macromodeling for Synthesis of Electronic Systems

建议编号：0429717研究：辛辛那提大学主校区PRINCIPAL研究员：Vemuri，RangaTITLE：电子系统综合的性能宏建模任何工程设计过程都包括两个广泛的活动：分析和综合。分析是预测给定设计的性能的过程。综合是提出备选设计的过程。在任何现实世界的设计过程中，都会重复执行分析和综合任务，直到找到合适的设计。计算机辅助设计系统使用综合软件，该软件生成大量的设计，每个设计都由分析软件模块进行分析。为了使这一过程在合理的时间内收敛到可接受的设计，分析过程必须快速和准确。传统分析方法使用设计构件的详细模型来模拟设计。不幸的是，这种方法虽然相当准确，但与自动化设计系统结合使用时速度很慢。另一种选择是使用性能宏模型，它们速度很快，但往往不太准确。这项研究解决了开发快速而准确的性能宏模型的问题。虽然这项研究将使用电子设计中的应用来指导研究方向并评估研究结果，但开发的技术将在任何工程设计学科中广泛使用。因此，这项研究有可能对开发高效的全自动化工程设计软件系统做出重大贡献。

PROPOSAL NO: 0429717INSTITUTION: University of Cincinnati Main CampusPRINCIPAL INVESTIGATOR: Vemuri, RangaTITLE: Performance Macromodeling for Synthesis of Electronic SystemsAny engineering design process consists of two broad activities: Analysis and Synthesis. Analysis is the process of predicting the performance of a given design. Synthesis is the process of proposing alternative designs. During any real-world design process, analysis and synthesis tasks are carried out repeatedly until a suitable design is found. Computer-aided design systems use synthesis software which generates a large number of designs each of which is analyzed by an analysis software module. For this process to converge to an acceptable design in a reasonable time, the analysis processes must be fast and accurate.Traditional analysis methods use simulation of the design using detailed models of the design building blocks. Unfortunately, this approach, while fairly accurate, is quite slow for use in conjunction with automated design systems. An alternative is to use performance macromodels which are fast, but tend to be less accurate. This research addresses the problem of developing fast, yet accurate, performance macromodels. Although this research will use applications in electronics design to guide the research direction and to evaluate the research results, the techniques developed will be broadly useful across any engineering design discipline. Thus, this research has the potential to make significant contributions to the development of efficient software systems for fully automated engineering design.
