Hi,
As per the download link in that documentation, it was successfully redirected us to Intel Community Wiki Sections. However, the required sample reference design was not posted yet at new Intel FPGA Wiki Platforms.
We are on the process of uploading sample design to this new wiki site and fixing the documentation errors. It required 1-2 months time to get this reference design upload because some internal code review activity & approval process.
Once we hear back from Intel Internal team about this sample design availability, we will let you know.
Thanks,
Joseph
