Hi,

sorry for the delay.

for Migrating an HLS design to DPC++ follow bellow steps.

  1. Add SYCL and FPGA headers
  2. Add FPGA Device selector
  3. Bind the device to a Queue
  4. Define shared memory
  5. convert kernel to a class
  6. Execute the kernel

I attached some example code details following the above steps one by one.

    The above response is for SYCL work flows for an application to be developed under oneAPI.

    Intel HLS compiler is used to generate an IP component that can/need to be integrated into other IP components in an RTL flow (using quartus). We do not require to use SYCL or CPU based multi threaded application, as the entire soft IP will run inside the FPGA. I am not sure, i am able to find a step by step instructions on how to migrate intel HLS project into oneAPI based compiler suite here. I will speak to somebody internally in the intel HLS team. Thank you for your replies, really appreciate it.
