The HLS compiler generates a number of reports for simulation, synthesis, co-simulation. These reports provide details about the high-level synthesis (HLS) process of a PL kernel. The main report is the Synthesis Summary report that provides estimated FPGA resource usage, operating frequency, latency, and interface signals of the custom-generated hardware logic. These details provide many insights to guide kernel optimization.

When running from the Vitis unified IDE, this report can be found in the HLS component directory named <hls_component>.hlscompile_summary. The Summary report can be opened from the Flow Navigator in the HLS component under the C Synthesis/Reports heading, or by opening the Compile Summary, or the Link Summary as described in Working with the Analysis View (Vitis Analyzer).
