基于OCP通信事务的SOC调试控制器

OCP Transactions-Based SOC Debug Controller

基于OCP通信事务进行SOC调试,提高了调试的抽象级别,对于以通信为核心的多核SOC,可以大大提高调试效率。为实现事务级调试,提出基于OCP通信事务的可配置调试控制器。通过分析OCP通信事务,该控制器根据预先配置的触发条件产生本地和远端调试控制信息,从而控制调试过程。通过对实验设计的仿真和综合,验证了调试控制器的功能,并分析了设计的面积开销。

OCP （open core protocol） transactions-based SOC debug improves abstraction level, which is more efficient for communication-centric MP-SOCs （multi-processor system-on-a-chip ） debug, A configurable debug controller was proposed to provide the controllability over the OCP transactions, By analyzing the OCP signals, the debug controller generates debug control information based on pre-defined trigger conditions for local and remote debug entities, The simulation of the experimental design demonstrates the functionalities of the debug controller while the synthesis result shows the area overhead.
