hello niosIIuser,

thank your reply. your meaning "After configuring the FPGA with the Programmer of Quartus II the Nios IDE should detect the Nios system well." Yes, i surely have done it.

my meaning is that: when before solder the EPM CPLD ,the SRAM and other device is running ok,but after that all device includeing ram on the FPGA are nonavailable. Dose the EPM associate with other device?
