I need help for creating only one pulse(cycle) signal on pressning of a 
button. I searched in forum and internet didn't find useful things. 
Everything is about "debouncing". I need a system debouncing+one pulse 
generator. If I press button it shall not create a signal for no longer 
than clock pulse. I am new in VHDL as well.
How can I do that?
Thanks.
