I'm working on a design that will require external memory, and I'm trying to find some learning resources for Xilinx DDR SDRAM memory controllers. I don't have much VHDL/FPGA design experience and all the resources I can find assume that you implicitly know how to use a memory controller.
The Xilinx models from their web site just unzip to a whole bunch of vhdl files and their documentation is not user oriented - it's an explanation of how their controller is implemented (I don't care!).
The memory controller performance/specification isn't important to me right now, but without being able to simulate a controller I can't proceed further with my circuit design. I'm using ISE and ModelSim.
Do I need to go down the Denali route and purchase a memory model then lean on their technical support? Or should I just give up and get a consultant to help?
