"2/3 or 3/4 of our customers are using HLS" ... I call BS on that statement. Don't get me wrong, Vivado HLS is a great tool, but no way this is true unless they use a very absurd definition of "using HLS". Also: Open sourcing libraries is nice but open source the tools!

Believe it or not! Thats the case. I have seen numbers myself.

Cool! Then you can hopefully clarify: What's the definition of "using HLS" in that statement? What is measured and how is it measured? And 2/3 or 3/4 of wha exactlyt? Companies? Individual users?

Using HLS - developing kernels in openCL/c++ . The number is more like 3/5 . count of kernels developed with HLS out of total kernel within some recent period. AFAIK.

So that's "kernels", not customers. What exactly is a kernel here? I guess not every IP core is a "kernel"? What percentage of Xilinx customers even have custom kernels in der FPGA designs?

Yes kernels are ips. The term comes from CUDA world. Almost all customer will custom ip cores + standard xilinx ips. What he meant was majority customers prefer HLS flow as primary development flow now.
