Here is the code (https://drive.google.com/file/d/1QcMYwOPU9onk4CiZx6YFD1pEYjXOSsbY/view?usp=sharing). I am using aoc 17.1 on VLAB
Here are the commands that you can run. (You might need to modify the Makefile according to your aoc setup):
% make compile-emulation
% make compile-host
% make run-emulation
This will pass and give correct results.
FPGA flow:
% make compile-device
% make compile-host
% make run
runs it on FPGA but the results are all 0s
Thanks,
Nitish

Hi Nitish,
What BSP are you targeting ?
Have you tried using the latest version of OpenCL compiler 18.1 ?
Thanks,
Arslan

Your code does not compile on my environment due to missing channel connections for “A_feeder_channel”. I am using aoc directly on your kernel. Furthermore, you have two writes to the “B_loader_channel” channel. Multiple call sites were not allowed until v17.0 and I would definitely avoid it even now that it is allowed. You are using very complex channeling operations, seemingly with multiple call sites in some places, and you are not enforcing channel ordering as far as I can see. This could very well be the reason for the incorrect output. The emulator fails at emulating concurrency properly; hence, you should not expect it to show concurrency issues that might exists in your kernel correctly.

Thanks for your replies HRZ and MUsman. The problem was multiple read/write channel calls for the same channel. Once I removed that, design started working.
