I recently received an Atera DE2 board with a Cyclone II FPGA. I have been experimenting with the expansion headers and I am having trouble understanding why my daughter card is not receiving any power. My DMM is reading 3.3 volts (when I connect the first JP0 pin and ground pins with logic code below), however, the voltage actually drops to something like .6V when it is connected. If I connect the constant VCC 3.3 volt pin and GND it works with no problem.
The extremely basic code:
library ieee; use ieee.std_logic_1164.all; entity expansion is port( a : in std_logic; y : out std_logic ); end entity expansion; architecture when_else of expansion is begin y <= a; end architecture when_else; --Pin Assignment a = PIN_N25 y = PIN_D25
