Hi, I have used the core generator for a DDR2 controller and I'm trying to implement my own user application. In my current simulation the controller comes out of calibration but when I try to write to memory the debug output tells me that the data are all X but the user interface waveforms look reasonable. I'm sure I'll find what the problem is in due time but I'm wondering if anyone who walked through this path has any suggestions. Also this is with the Xilinx memory model. I tried a Micron specific memory model I downloaded separately
Thanks.
