采用JTAG结构实现SoC芯片的片上仿真器及接口

An Implementation of the SoC On-Chip-Emulator and Interface Used JTAG Architecture

片上仿真(OnChipEmulation)是系统级芯片(System-on-a-Chip,SoC)进行调试与诊断的新型方法。文章讨论了一种采用JTAG结构实现SoC芯片片上仿真器的方法。此方法已应用于以CCORE为核心的SoC设计平台上。

The On-Chip-Emulation is a new method of debugging and diagnoses for the System-on-a-Chip(SoC).An method of implementation of the SoC On-Chip-Emulator and interface used JTAG architecture is discussed in this paper.And this method had been used in the SoC platform based on the CCORE.
