DDR3 "verify fail" when applying little modifications in Qsys

Hi ,

I have designed a NIOS II-e based system running on DDR3 memory and the system works fine but when I do small modifications in QSys (eg. add an interval timer) in some cases I face "verify failed" when programming NIOS2.

My platform is Stratix IV Development Kit. NIOS II processor is connected to DDR3 controller reset and clock(afi_half_clock: 75Mhz).

Thanks in advance
