8 years agoFPGA 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%?4 Replies

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)
