基于UML的SoC建模设计方法研究

随着集成电路制造工艺的发展,嵌入式计算机应用向着SoC的方向发展。为了适应制造工艺对SoC设计能力的要求,提高SoC的设计效率,成为了很紧迫的必要任务。采用统一的SoC系统级建模语言SystemC、软/硬件协同设计技术、基于IP核复用等技术的SoC设计流程,在一定程度上满足了SoC设计要求。在现有SoC设计流程基础上,结合UML的模型驱动框架（MDA）设计方法,在当前的SoC设计流程的系统需求规约描述、硬件实时反应式系统建模、软件模块设计实现中采用UML针对SoC的轻量型扩展特性,可以很大程度地改进提高SoC的设计流程效率。

Research of SoC Modeling Design Method Based on UML

As the development of the IC manufacture technic,the application of embedded computer system developed in a trend to SoC(system-ona-chip) application.To fit a higher SoC design ability which required by manufacture technic,improving the SoC design efficiency becomes an urgent and essential task.Involving many technologies such as unified SoC system-level-modeling-language,SystemC,the hardward/software co-design technology,and IP core based reuse technology,the current SoC design flow basically meet the SoC design requirement.Introducing the mode-driven-architecture(MDA)design method of UML into the current SoC design flow,and according to the UML 2.0 profile for SoC v1.1 specification, using the UML modeling language in the system-requirement-specification describing,hardware real-time reactive system modeling,software module designing and implementation,the UML modeling language greatly improved the SoC design flow and the SoC design efficiency.
