In your component tcl file, you need to set the isMemoryDevice option to "true". Look at this post http://www.alteraforum.com/forum/showthread.php?t=24306

Hi Ironmoose,

Thank you for your advice. But this feature is depricated now in QII 9.1 SP2. I did give it a try anyway and the SOPC builder did recognize the sram controller as one of the option for reset vector and exception vector, but it breaks the NIOS in a way that I can't even run a hello world program. The functional simulation also failed at one of the assertions in the cpu testbench.

Since this is depricated, is there a formal way of setting a IP as a memory device? A link to an Altera documentation would be much appreciated.

Thanks,
