FPGA Programming

The Challenge In order to make this Verilog program, I adapted the one described at to the clock frequency of the hardware used in this challenge which it 125Mhz. The counter is so decremented by CLOCK_FREQUENCY/(2*freq/100) converted to integer through $rtoi method. Here are the results of the different tests: At 500Hz At 1KHzContinue reading “FPGA Programming”
