研究内容

模型驱动开发技术广泛用于航空航天、汽车、轨道交通等安全攸关的重要领域。传统的手动软件开发方法面临着重要挑战，开发效率和代码安全性难以得到满足。而采用基于模型的嵌入式系统设计则可以有效地减少软件系统错误的发生。模型驱动开发流程主要包含四个阶段：建模、仿真、测试和代码生成。

1. 基于中间表示的统一的代码生成框架(右图)。现有的建模工具在不同领域的建模能力差别很大，将不同的建模工具结合起来进行模型驱动设计可以实现其功能的充分利用。针对模型驱动的软件开发提出了基于中间表示的统一的代码生成框架，该框架能够向前对接不同建模工具，向后对接不同用途的代码生成。目前学术界已有10余篇高水平论文基于该框架实现，相关研究包括模型的高速仿真、模型测试、高性能代码生成等。这些论文相比SOTA的工作均获得了显著的效果提升。(相关成果[1-13])

2. 模型的高质量代码生成。代码的质量直接影响嵌入式设备的运行效率。越高的代码执行效率意味着系统响应越快、调度越流畅。针对传统代码生成器面临的诸多致使代码效率低的问题，比如向量处理器未被充分利用、处理器流水线阻塞、冗余计算代码等。完成了SIMD指令生成、流水线调度优化、冗余代码精简等一系列工作，能够针对广泛的模型进行高质量的代码生成。在不同模型场景下相比SOTA的工作取得了1.2-16倍的代码效率提升。(相关成果[4-5][10-12])

3. 高效高覆盖的模型测试。模型测试是模型驱动开发过程中的重要步骤，它关系到最终系统的安全稳定运行。自动测试用例生成技术可以让测试人员从复杂的用例构建任务中解放出来，能够帮助用户快速发现模型的设计缺陷。传统的基于约束求解方法和基于随机仿真方法面临状态空间探索慢、覆盖反馈效率低的问题。提出了状态感知求解、模型模糊测试以及两者结合的模型测试用例生成方法。特别是针对状态和逻辑复杂的模型，这些研究相比SOTA的工作取得了约35倍的效率改进和60%的覆盖率提升。(相关成果[6-9])

4. 应用落地。开发了一套模型驱动开发工具集MBD，其核心是基于中间表示的代码生成框架，目前涵盖了Simulink模型解析、Ptolemy模型解析、动态数据流/数据流模型调度转换、多个代码优化模块、面向模型仿真/测试/验证/部署的多个代码翻译器（包含苏卓博士所有相关成果的先进技术）。工具集包含20多万行代码，目前已并入华为代码仓库，同时该工具集已在华为自研的行为建模工具中应用，并在华为汽车生产线和多家友商车企应用落地。
