11 years ago --- Quote Start --- I have sent you an email also. --- Quote End --- Thanks! --- Quote Start --- I have tried that JTAG-to-Avalon master tutorial but it just uses on-chip RAM. If I wish to use the separate SDRAM on the DE0-nano board, do I just add an SDRAM controller in Qsys instead of on-chip RAM? --- Quote End --- The tutorial is written to be board agnostic, so it does not use any external devices. In your case, you would simply *add* an SDRAM controller to the Qsys system, and assign it a base address that does not conflict with the existing memory map. --- Quote Start --- How would I then make sure that it communicates with the SDRAM on the board. Looking at the DE0-nano user guide , there are many pins connected to the SDRAM so which pins would I need to assign and to where? --- Quote End --- The attached zip file contains a top-level design and a constraints file that defines all the pins on the DE0-nano. If you cannot figure out how to add an SDRAM controller to the design, I can take a look, but you should try to figure it out, as it will be a good learning experience. You should also try to figure out how to create a simulation for the system (that will likely be a little trickier though). Cheers, Dave
