Where to get the synthesis report of the OpenCL kernel?

For each OpenCL kernel, I want to get the exact resource utilization(after PAR) and frequency. But, I do know where they exist?

    If you navigate to the sub-directory named after the kernel file you'll find report files in there containing information. I don't have a compiled project on this machine but the files to look for have .rpt file extensions.

    Note: it's not expected that OpenCL users will be digging around in hardware reports so the way this information is presented/stored may change in later versions of the tools.

    I have checked the .rpt and .summary files and have gotten the exact resource utilization. Thanks.

    However, I can not find the operating frequency in the .rpt files.

    I went ahead and compiled a small kernel so that I can look at the output file set. I recommend using the file called "acl_quartus_report.txt" which will contain the hardware resources and kernel clock frequency. The kernel 1x clock is what the kernel logic (all the kernels in the .cl file) operate at in the hardware.

    Yes, "acl_quartus_report.txt" contains the kernel clock frequency. Is there any file report about whether the timing constraint of the kernel is satisfied at the given clock frequency?
