    A few things: 1) I see an instantiation of a ROM, but I don't see a component declaration. 2) How are you initializing the ROM with a .mif file? I don't see a synthesis attribute to do this unless you have created the ROM as an IP and set the .mif as a parameter setting. 3) To use System Console, there is usually a Platform Designer system (.qsys) with a connection from a JTAG-to-Avalon master bridge to a slave interface. Where is that here?
