本文首先分析了软件调试技术的两种调试模型和硬件调试技术的几种调试方式，并对软硬件调试的优缺点进行了对比分析。然后具体研究了仿真开发平台IshIl框架，仿真运行机制和调试系统的工作流程。最后设计并实现了一种基于仿真开发平台的调试系统。它包含仿真交叉调试和软件OcD调试，提供友好的调试界面，使用统一的调试命令接口，可扩展支持多种调试通信协议和不同协议的调试器。仿真交叉调试子系统根据程序有无操作系统支持，提出了两种调试模型。宿主机端封装GDB调试器为核心，目标机端的调试代理与仿真运行环境管理器协作完成具体调试功能，两者通过RsP协议进行通信。软件OCD调试子系统利用IshIl基于信号传递的系统驱动技术和周期精确的时序仿真技术特点，解决了硬件相关的调试需求。-This paper analyzes both the software debugging techniques and hardware debugging model several debug mode debugging techniques, and debugging of hardware and software advantages and disadvantages are compared. And specific studies of the development platform IshIl simulation fr a mework, simulation and debug system operation mechanism workflow. Finally, design and implement a development platform based on simulation debugging system. It contains the simulation of cross-commissioning and commissioning software OcD provide friendly debugging interface debug command interface using the unified, extensible support for multiple communication protocols and different protocol debugging debugger. Cross debugging subsystem simulation program with or without operating system support under the proposed two kinds of debugging model. Host-side core package GDB debugger, target-side debugging and simulation of agents collaborate to complete operating environment manager and commissioning functions, b
