    We tried adding the -high-effort flag but got the same results

      How long does it take from when you run the command until you receive the error? If it takes more than an hour, then your kernel is likely too complex for the compiler to process. The "-high-effort" is for placement and routing and will not affect your case; your kernel compilation is failing in the OpenCL to HDL conversion step, not placement and routing.

    Hi,

    You can try to update to Quartus Prime Pro 19.3.

    If the problem still persist please tell me as well.

    Thanks

      I am using the Quartus 19.3.

      I am getting the same error. The code works for emulation.

      However while compilation Optimizer failed.

      Probably I have to reduce the complexity of code.
