I do not currently have a license for the OpenCL SDK, and I also do not have a board that is supported by it. I am wondering if there is any way to use OpenCL generically for an FPGA. I have a Max 10 dev board right now, but due to time constraints would like to program it using OpenCL rather than manually writing HDL.
I am afraid OpenCL is not supported on Max 10 FPGAs. Support only exists for Cyclone V, Stratix V, Arria 10 and Stratix 10 (and maybe also Cyclone 10 but I am not sure). Furthermore, your board must come with an OpenCL Board Support Package (BSP) or else you will have to create one to be able to use OpenCL which will not be an easy task. However, no OpenCL license is required starting from Quartus/OpenCL SDK v17.1 anymore and as long as you have a valid Quartus Standard/Prime license, you can use OpenCL.
OpenCL is available with license only.
For Max10, there is not OpenCL support.
OpenCL can be supported on Cyclone V, Stratix V, Arria 10 GX and Stratix 10.
