FPGA resources usage

Question

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%?

Hi, thanks fot your reply! Should I use either "Logic utilization" or "ALUTs" to estimate resources usage? Thank you!

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

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)
