HI.
Now I'm trying to implement the xilinx fifo into my FPGA as below.
But I think the FIFO does not work. I just make it where from Coregen of ISE tool.
fifo1.v
and I use as below by instance.
Is that right to implement fifo what I use fifo.xco?
Would you please let me know what I am missing?
What am I suppose to do?
