基于接口的IP模块可重用设计方法

INTERFACE-BASED IP MODULE DESIGN REUSE METHODOLOGY

IC设计复杂度的快速增长和市场压力的增大,要求重用已有的设计以提高设计能力。该文分析了模块间通讯方法,认为基于接口的设计可以更好地实现设计的重用。通过对基于接口的设计方法的研究,根据摩托罗拉半导体IP接口(IPI,IP Interface)标准,建立了基于接口标准的IP模块设计方法和设计环境;最后结合使用基于接口的设计方法和基于层次化的片上系统总线结构的设计方法,进行了实例设计。

The rapid increase in IC design complexity and greater time-to-market pressures require reuse of complex pre-defined design blocks to improve design productivity. By analyzing the communication between modules, this paper draws a conclusion that interface-based IP design methodology can improve design reusability. Interface-based IP design methodology and environment is built according to MSRS (Motorola Semiconductor Reuse Standard). A case is given which combines both hierarchical bus architecture and interface-based design methodology.
