Hi,
I am trying to use the DDR2 SDRAM DIMM on the Stratix III eval board. http://www.altera.com/products/devkits/altera/kit-siii-host.html I am following the directions at: http://www.alterawiki.com/wiki/design_example_-_stratix_iii_ddr2_sdram_uniphy_400mhz_x72 The design seems to synthesize fine. After boot, calibration succeeds, so I think some parts of the DDR2 system are working. But when I try to trigger a single read on Avalon, I never get a response. I'm following the signals described on p 3-9 of http://www.altera.com/literature/manual/mnl_avalon_spec.pdf This is using Quartus 13.1. Any suggestions on how to troubleshoot this? Thanks. Also, since I'm using a stock eval board with the stock SDRAM DIMM, perhaps there is a reference implementation somewhere? Thanks very much, J.- Tags:
