摘要
系统建模是嵌入式系统设计的关键步骤,其好坏直接影响着设计的质量和产品的上市时间。已有多种建模方案,但每种都有其局限性。本文提出一种由5层模型组成的嵌入式系统设计的模型框架。它能够从需求描述开始,建立CDM功能模型,经一致性验证,满足设计要求后映射到SystemC抽象模型上。利用SystemC的硬件描述特征和仿真库,增加设计细节,分层细化模型并进行验证,最后达到软硬件的协同设计和综合实现的目的。
System modeling is an essential design in embedded system. It will directly affect design quality and time on market. Nowadays, there are some modeling solutions, but each of them has its limits. In this paper a new modeling frame of embedded system design is presented that consists of 5 level abstraction models. The suggested solutions make up of specification the product ~s requirements, establishing CDM model, consistently verifying these constructed components to satisfy the requirements of design, and mapping them into the SystemC abstraction models. With SystemC hardware properties and simulation kernel, the models can be gradually refined and verified by adding details. The suggested approaches get the aim of the hardware-software co-design and synthesis implementation.
