This chapter describes the utility tools included within the Vitis™ AI Development Kit, most of them are only available for the Edge DPU, except for the Vitis AI Profiler, which is a set of tools to profile and visualize AI applications based on the VART. The kit consists of five tools, which can be used for DPU execution debugging, performance profiling, DPU runtime mode manipulation, and DPU configuration file generation. With the combined use of these tools, you can conduct DPU debugging and performance profiling independently.
