I want to add a few additional pushbuttons to my design but I encountered some problems. I have two questions:
- How do I have to implement such buttons in VHDL? This is what I’ve done so far:
in the VHDL-file:
addbutton1 : in STD_LOGIC;
and in the constraints file:
NET “addbutton1” LOC = “P42”;
- Maybe the mistake is in my electronic ciruit. Is there a circuit diagram or xilinx documentation available that shows how to implement such a circuit properly? Which circuit was used for the four XEM3001 pushbuttons?
Thank you in advance for your answer!
