I am trying to compile an OpenCL kernel for my FPGA. However, I get an error message, saying that I don't have enough resources on the device: " Error (170011): Design contains 100933 blocks of type combinational node. However, the device contains only 83820 blocks. "
However, this is not true. According to Estimated Resource Usage Summary the design uses 56% of the total available ALUTs. Also, according to specifications(Cyclone V SX) and kernel compilation report, I have 110K(109572) ALUTs which is more than 83820 given in the error message. What can be the actual limiting factor for my kernel design?
