TLM Wrapper,建立一套基于TLM模型的通信机制,将QEMU包装成TLM模型,使QEMU模拟的设备能够与SystemC开发的模块进行通信。 AMBA Router,以软件形式模拟AMBA总线,实现了标准的AMBA路由机制和仲裁机制,可将多个TLM模型连接并进行数据通信。 AXI TLM,是一个基于AXI总线的TLM模型,负责将AXI接口设备适配到AMBA Router总线上。
混合仿真验证前,通常优先开发抽象SystemC模型(如TLM模型),然后将此模型转化为RTL并基于此模型上开发软件。在此过程中,软硬件的诸多错误能尽早被发现,从而节省开发时间。 使用QEMU和SystemC可以共同组成虚拟验证平台,实现SoC系统级建模。 图2 SystemC Simulation 3. 基于QEMU的混合仿真验证 混合验证是一种方法,它在...
QEMU is a popular open-source simulator with a large library of processor and peripheral models. However, it is limited in flexibility as it offers no standardized interfaces. QBox (Qemu in SystemC Box) extends QEMU with SystemC TLM-2.0 interfaces, enabling the usage of QEMU processor and per...
