I want to compare data inside FPGA and output the maximum value, but there is a problem during simulation. I hope you can answer this question!
Let me first tell you my idea: I want to continuously send 8-bit data to the FPGA, and then send out the previous largest data (so I need to keep comparing) when a certain IO port is at a high level. ...
