Hi,
I'm trying to interface QDRII memory (CY7C1263V18-400) with my NIOS II processor using SOPC builder on my Stratix III devellopment kit. Each time I try to add the UniPhy QDRII controller I've got the following warnings: Warning: QDRII.avl_w: writedata[72] width must be in {8, 16, 32, 64, 128, 256, 512, 1024} for dynamic addressing Warning: QDRII.avl_w: byteenable[8] width must be 9 (data width/8) Warning: QDRII.avl_r: readdata[72] width must be in {8, 16, 32, 64, 128, 256, 512, 1024} for dynamic addressing Furthermore, when I try to generate the system I obtain the error: # 2010.01.19 13:54:53 (*) Making arbitration and system (top) modules. ERROR: slave data width (72) for slave QDRII/avl_r unexpected 9 Then I tried to use the DDRII (MT9HTF12872AY-800E1) but I obtained the same type of warnings and errors. I'm dying trying to resolve this problem, can someone help me plz ?Link Copied

Hi,
It's just one click away "Generate power-of-2 bus widths" on "Advanced Settings" A good reference is the "External Memory Interface Handbook" I'm also trying to use the QDR memory of Stratix III dev Kit, with NiosII and SOPC . I still have issues with the top level connections of these pins, do we need another top level IP to drive them ? .MEM_QDRII_afi_clk_out(), .afi_cal_fail_from_the_MEM_QDRII(), .afi_cal_success_from_the_MEM_QDRII(), .afi_reset_n_from_the_MEM_QDRII(), .dll_delayctrl_from_the_MEM_QDRII(), .mem_doff_n_from_the_MEM_QDRII(), .oct_rdn_to_the_MEM_QDRII(), .oct_rup_to_the_MEM_QDRII(), .pll_addr_cmd_clk_from_the_MEM_QDRII(), .pll_afi_clk_from_the_MEM_QDRII(), .pll_locked_from_the_MEM_QDRII(), .pll_mem_clk_from_the_MEM_QDRII(), .pll_write_clk_from_the_MEM_QDRII(), Thanks
