Hi! I am trying to create a timer that counts down from 6 to 0 and then activates a buzzer. I am using the 50MHz clock on the board and divide the frequency to 1/60 Hz so that the counter (connected to the 7seg display) counts down in minutes. This part works. I am also dividing the 50MHz clock on the board to get a frequency to send to the buzzer, but the buzzer will not activate. I am using the L15 pin and GND on the board for the buzzer. I have tried a range of 400-4000 Hz. Any ideas as to why the buzzer won't activate? The buzzer is working since I tried connecting it to a 3.3V pin and it activated.

So maybe it is an active buzzer that simply needs a supply and not a AC- or pulse-signal. Katja wrote: > The buzzer is working since I tried connecting it to a 3.3V pin and it > activated. How much current needs this buzzer? More than a FPGA pin is able to source? But first question is: is the simulation ok and running fine? What? You didn't simulate? Well, know: the simulator is the debugger in a hardware design. And your kind of design is easily simulated as most of the stimulus is a clock with 50MHz...
