    I am using Sockit Arrow board rev D (Terasic - SoC Platform - Cyclone - SoCKit - the Development Kit for New SoC Device) with Cyclone V(5CSXFC6D6F31C6N), DDR3 chip is IS43TR16256A (issi.com/WW/pdf/43-46TR16256A-85120AL.pdf).

    I programmed the .sof file through Demonstration Batch File in SoCKit_DDR3_Nios_Test example, and problem was happened. The architecture of example is below:

    I tried to run EMIF toolkit (in Quartus 13.1), the memory connection is:
