Single Pulse in output with pulse width ibility control

Hi everyone. I have used many ways to create single out pulse with pulse width bility. So far as I know I have to use counter to count clock pulses and make the output one and zero. I have used st...

The initial high is while the FPGA is being configured. Once configured the output is driven low and fires a single pulse as your state machine describes.

If you want your output to be low during configuration you have to add a pull-down resistor to the FPGA's pin.

Thanks for your time josyb.

I have tried to change the pull-down resistor located in Pin planner but there wasn't any change in output. I would really appreciate if you be more specific with examples or extra information. I have heard of External pull-down resistor? any idea how it works?
