    Default FPGA resources usage

    Hi, after I compile my opencl code, the resources usage as flows:

    +--------------------------------------------------------------------+
    ; Estimated Resource Usage Summary ;
    +----------------------------------------+---------------------------+
    ; Resource + Usage ;
    +----------------------------------------+---------------------------+
    ; Logic utilization ; 139% ;
    ; ALUTs ; 59% ;
    ; Dedicated logic registers ; 81% ;
    ; Memory blocks ; 210% ;
    ; DSP blocks ; 73% ;
    +----------------------------------------+---------------------------;

    The FPGA is Arria 10. I want to know what's the relationship between 'Logic utilization' and 'ALUTs'. Why 'ALUTs' is 59% but 'Logic utilization' is 139%?

    Logic utilisation is the more important. as you can see, as logic usage is > 100%, it will not fit in the device. (you also have 210% ram usage, so no chance)

    Thanks for your reply!
