DDR2-SDRAM High performance controller

Hi All,

I am currently using the DDR2-SDRAM High performance controller on Quartus II 8.0. I assume that the controller had been successfully generated. but i can not effectively test the the system as the example driver always hangs.

I have noticed using signal tap that the signal mem_local_rdata_valid never got asserted by the controller.

Does anyone have experience with this?

Thanks

Test conditions:

Stratix II EPS30F67

Micron's DDR2 MT47H16M16

Quartus II 8.0

    I used the starter edition of ModelSim. You have to follow the procedure given in the DDR2 user guide. I could not simulate DDR2 HPC directly from ModelSim as I was doing something wrong. But, if you launch the simulation from Quartus tool it worked(follow the simulation procedure from user guide). One good thing with Altera's simulation is, you need not write any code :).
