Is there any way in SOPC builder or Qsys to use a costume memory as main processor SRAM? In my build I can only use of on chip RAM or ROM. NIOS processor can not detect another type of memory as its SRAM!

You mean use SRAM or SDRAM as Memory for the NIOS?
If this is the case, this is possible. but be aware to set the exception and reset vector correct, so that this will work...- Mark as New

I try to connect the memory reset and execption to my memory but SOPC builder does not let me to do that. I can only connect it if the memory is On-Chip Memory (ROM/RAM) type of memory!

If you are creating your own custom component which is representing some memory, then you need a special setting in your hw.tcl
