HOW do I write from a Spartan6 to the Micron exter

问题:

I have looked everywhere, the datasheet, the Xilinx website, digilent, etc. etc. and can't find anything! I was able to use the Adept tool to verify that my Cellular RAM is functioning correctly, but I just can't find any stock VHDL code as a controller to write data to and read data from it!! Help!!

Found this link but it's for asynchronous mode, which is not nearly fast enough: http://embsi.blogspot.com/2013/01/how-to-use-cellular-ram-from-micron.html

Eventually found this on the Nexys 2 Digilent page: http://www.digilentinc.com/Products/Detail.cfm?Prod=NEXYS2 under "Onboard Memory controller reference design" It's just a shame that this was not included with Nexys 3 details as it would have saved a lot of time! Hopefully somebody else with this issue could at least find what I posted here and find it quickly...
