This project is a new approach to system-on-a-chip design, called deconstruction. The approach starts with an existing prefabricated, parameterized, reference design in silicon, composed of hundreds of Intellectual Property (IP) blocks, and then deconstructs it into the desired system by setting parameters. In contrast, the current approach is to construct a desired system by combining IP and then generating silicon. This approach has serious verification limitations. The techniques being developed focus on making deconstructed systems competitive with constructed systems in terms of design metrics like power, performance and size. The emphasis is on two issues relating to flexibility in reference designs: (1) Formalizing the notion of parameterized reference designs, consisting of a sound parameter classification scheme, and a precise method of specifying such parameters, and (2) Developing models and algorithms for parameter optimization, requiring system-level models of power and performance metrics from which metric values can be rapidly computed. Such optimization is being achieved by developing techniques based on cost ranges, rather than single cost values, to evaluate candidate solutions.

该项目是一种新的芯片设计方法，称为解构。 该方法从硅中的现有预制，参数化的参考设计开始，由数百个知识产权（IP）块组成，然后通过设置参数将其解构为所需的系统。 相反，当前的方法是通过组合IP然后生成硅来构建所需系统。 这种方法具有严重的验证限制。 开发的技术重点是使解构系统在设计指标（例如功率，性能和尺寸）方面与构造系统竞争。 重点是与参考设计灵活性有关的两个问题：（1）形式化参数化参考设计的概念，包括声音参数分类方案组成，以及一种指定此类参数的精确方法，以及（2）开发模型和算法，以进行参数优化的参数优化，需要从该系统级别的模型和性能的模型，从而可以快速计算计算。 通过基于成本范围而不是单个成本值来评估候选解决方案的成本范围而不是单个成本值来实现这种优化。
