Development of Comprehensive Set of LSI CAD Benchmarks

我们已经开发了一套全面的基准定量评估LSI CAD工具。基准测试集在几个抽象层次上描述了同一个电路，因此我们可以自由地设置任何类型的基准测试。一套标准的过程独立的库已经开发的基准集。KUE-CHIP 2被选为第一个候选基准测试程序，我们的主要工作总结如下：1.标准库集的开发我们开发了一套标准的工艺无关库，以CMOS标准单元库的形式。该库集旨在用于综合基准，也可用于公共领域的免费库，用于研究和教育用途。标准库不是一组单独的库，而是一组库生成工具，它可以根据多个工艺参数自动生成特定于工艺的库。版图生成采用符号化的方法。延迟和功耗特性分析的一个新的分析方法，考虑在信号过渡期间的短路电流。标准库通过模拟和测试芯片进行验证。2.开发一套全面的基准作为全面基准集的第一个例子，我们选择了KUE-CHIP 2，这是一个8位微处理器开发的教育用途。KUE-CHIP 2的VHDL描述已经被开发并且通过一组用于功能验证的测试模式被验证，所述测试模式与其原始UDL/I模型一起提供。3.评估一组全面的基准测试KUE-CHIP 2基准测试已经通过使用标准库执行逻辑综合到自动布局来进行评估。它是成功地评估使用概要（逻辑综合）和联盟（自动布局）的设计工具。

We have developed a comprehensive set of benchmarks for quantitative evaluation of LSI CAD tools. The benchmark set describes the same circuit in several levels of abstraction so that we can set up any type of benchmarks freely. A standard set of process independent libraries has been developed for the benchmark set. KUE-CHIP2 is selected for the first candidate of the comprehensive set of benchmarks.Our achivements are summarized as follows.1.The development of standard set of librariesWe have developed a standard set of process independent libraries in a form of CMOS standard cell libraries. The library set is intended to use in comprehensive benchmarks, and also for public domain free libraries for research and educational use. The standard library is not a single set of libraries but a set of library generation tools that automatically produce process specific libraries from several process parameters. Symbolic layout method is used for layout generation. Delay and power dissipation characteristics are analzed by a new analytical method that considers short circuit currents during signal transition. The standard libraries are verified by simulation and also by a test chip.2.Development of a comprehensive set of benchmarksAs the first example of the comprehensive benchmark set, we have selected KUE-CHIP2 which is a 8-bit micro processor developed for educational use. VHDL description of KUE-CHIP2 has been developed and verified by a set of test patterns for functional verification which is supplied with its original UDL/I model.3.Evaluation of a comprehensive set of benchmarksThe KUE-CHIP2 benchmark has been evaluated by performing logic synthesis down to automatic layout with the standard libraries. It is successfully evaluated using Design Compiler of Synopsis (logic synthesis) and Alliance (automatic layout).
