Hi,The HPCII native interface documentation is very poor, so I try to simulate my design to verify read and write operations. I use Quartus 10.1 sp1 / modelsim 6.6c HPC II : - PSC A2S56D40CTP-G5 DDR (cycIII starter kit DDR), burst x4 - full calibration & generate simulation model options I made a testbench with my ddr_driver (which drive local signals), ddr IP and quartus generated memory model. The internal PLL works (phy_clk, mem_clk, aux_full_rate_clk... are generated) but the DDR IP seems to fail its initialization/calibration : - local_init_done, local_ready, ctl_cal_fail, ctl_cal_success... are all at '0'. Is it possible to simulate ddr calibration ? How can I pass this step and get local_ready asserted ? Thanks.
