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。
On-chip emulation (OnChipEmulation) is a system-on-chip (System-on-a-Chip, SoC) debugging and diagnosis of a new method. This article discusses a method of implementing a SoC on-chip emulator using a JTAG architecture. This method has been applied to CCORE core SoC design platform.
