摘　　要：汽车开放系统架构有助于复杂的汽车电子软件的开发、管理及维护,交易级建模在较高抽象层次对系统进行建模,提高了建模速度。针对基于AUTOSAR的软件设计流程,采用SystemC语言及其提供的时间行为和硬件仿真核,进行交易级建模层次化设计和通信细化。重点分析了AUTOSAR描述语言和SystemC语言之间的相似点,并且设计了AUTOSAR环境到SystemC虚拟原型设计的转换过程。结果表明,这种建模方案能有效地实现符合AUTOSAR规范的汽车电子系统的仿真,仿真速度快,有利于系统设计早期阶段验证及性能分析。AUTOSAR contributes to the development, management and maintenance of complicated automotive electronics software. Transaction-level Modeling builds the model of a system at a higher level of abstraction and improves the modeling speed. For AUTOSAR-based software flow, SystemC Language and the time behavior and hardware simulation kernel were used, which offered to design in hierarchy and communication refinement by Transaction-Level Modeling method. The similarities between AUTOSAR descriptive language and SystemC language were discussed, and the conversion process from A UTOSAR environment to SystemC virtual prototype was designed. The results show that the modeling scheme can realize the simulation on automotive electronic systems conforming AUTOSAR specification, and the simulation speed is fast and it is conducive to the verification and performance analysis of the early staees of design.
