Diagnose AOC: Internal Compiler Error

Hi Peter,

Usually I get the internal compiler error when I've got too demanding a kernel,

and the compiler simply cannot find a hardware implementation for it, given the FPGA resources.

It's often a good lesson in efficiency, but this time that wasn't the case.

I found from the resource usage report and early usage estimates that I should have been fine.

So I tested with the hello_world example off the Altera website, and sure enough it too failed to compile,

even though I had compiled its .aocx a month before without issue.

I am not sure as to whether our problems are the same, because I ran a string search in my .log file for "Error" (case-insensitive) and nothing came up.

It seemed there was something off about the AOC so as I said before, I did a reinstall of the Altera OpenCL SDK, and it works fine now.

Again, my .log file didn't show any issue, so I'm not sure if we have the same problem, but you could give it a try.

If you haven't checked already, you can check the resource usage to see if there is too great a demand on your FPGA hardware resources.

Best regards,

Victor

Edit: There could also be something wrong with the code implemented by your .cl file.

I remember getting internal compiler errors before because I made silly mistakes or assumptions.
