Simulating Software Running on a Nios II Processor

Hi, I got problem when Simulating Software Running on a Nios II Processor. The Nios II Processor is generated by Qsys. The step is as follow: qsys: 1. On the Generation tab, set Create testbench...

I also could not get a simple hardware up. There seems to be something strange in the "memory initialisation file" file setting for the onchip ram.

IF the memory name is InsMem then two .hex files are created. One in the Qsys folder (InsMem.hex) and another in the "synthesis" folder (InsMem_mem.hex) The InsMem.v seems to access the InsMem.hex and the .qip file (added to quartus) the "InsMem_mem.hex"

The NIOS IDE only accepts the InsMem.hex. Do'nt know what file the Quartus uses to update MIF, but both seem to be called.

I update the MIF file and configure the FPGA using an intelligent host. External logic is fine, but NIOS work run. Looks like memory is not getting updated.

Same technique worked fine in Quartus 10/SOPC with no problem.
