Can someone explain how to write to and read from bee2 DRAM? I have a simple model which attempts to write numeric values of 0 through 255 into 256 locations, then read these values back and capture them in BRAMS so that "bramdump" can be used to look at the contents. When I run this design in a bee2 USER FPGA, the resultant data out of the DRAM is simply flat-lined as all zeros.
