The growing complexity of embedded and cyber-physical systems makes the design of all system components from scratch increasingly impractical. Consequently, already from early stages of a design flow, designers rely on prior experience, which comes in the form of legacy code or third-party intellectual property (IP) blocks. Current approaches partly address the co-simulation problem for specific scenarios in an ad hoc style. This work suggests a general method for co-simulation of heterogeneous IPs with a system modeling and simulation framework. The external IPs can be integrated as high-level models running in an external simulator or as software- and hardware-in-the-loop simulation with minimal effort. Examples of co-simulation scenarios for wrapping models with different semantics are presented together with their practical usage in two case studies. The presented method is also used to formulate a refinement-by-replacement workflow for IP-based system design.

嵌入式和信息物理系统设计的异构协同仿真

嵌入式和网络物理系统日益复杂，使得从头开始设计所有系统组件越来越不切实际。因此，从设计流程的早期阶段开始，设计人员就依赖以前的经验，这些经验以遗留代码或第三方知识产权 (IP) 块的形式出现。当前的方法部分地以一种特殊的方式解决了特定场景的联合仿真问题。这项工作提出了一种使用系统建模和仿真框架对异构 IP 进行协同仿真的通用方法。外部 IP 可以集成为在外部模拟器中运行的高级模型，也可以轻松集成为软件和硬件在环模拟。在两个案例研究中，展示了用于包装具有不同语义的模型的联合仿真场景的示例及其实际用法。所提出的方法还用于为基于 IP 的系统设计制定逐个替换的细化工作流程。
