Hello,
I am trying to implement an 8 bit adder program using VHDL on Virtex 2 pro with expansion kit DIO4 from digilent.
The code is correct and I can see the result on 4 LEDs of Virtex 2 pro kit from Digilent. But when trying with LEDs on DIO4 kit, I could not see any result. I gave the direct pin connections both for switches and LEDs. The switches are working fine but not the LEDs. In the reference manual, I observed that there is latch between LEDs and connector P1. But I dont know how to use latch for this program.
Can any one guide me how to solve this problem?
