Hi all,
I am trying to use SOPC_Builder to build my NIOS system. But after the NIOS symbol is generated, I find that some pins which I can't find out in the datasheet of DDR2 SDRAM. So how to assign these pins correctly? The following is the pins which does not exist, DDR2_SDRAM_aux_full_rate_clk_out DDR2_SDRAM_sux_half_clk_out DDR2_SDRAM_phy_clk_out Local_init_done_from_the_DDR2_SDRAM Local_refresh_ack_from_the_DDR2_SDRAM Local_wdata_req_from_the_DDR2_SDRAM Reset_phy_clk_n_from_the_DDR2_SDRAM Here is the hardware, software, nios2 system I used Quartus II version 9.1 SP2 full version Cyclone IV E: EP4CE15F17C7 Nios2 system: CPU(clk : External clk =100MHz) EPCS Serial Flash Controller(clk : External clk = 100MHz) DDR2_SDRAM (64MB,8bit wide, Discrete Device, CAS 5.0, 1 Chip Select, the parameters was Modified form Micron MT47H64M8CB-3) PIO(clk : External clk = 100MHz) sysid (clk : External clk = 100Mhz) Can anyone help me to solve my problem, Thanks!!!链接已复制
