now, I have one more question.

if I want to use the niosII soft IP core, I should download the .sof file to the DE2 board, then the hardware of the system has been setup. And then, I run the niosII IDE to run software on the hardware which has been setup. It is right that I store the software on the FPGAs internal block RAM, but when I redownload the .sof file, the RAM in the FPGA should be cleared up. I definitely understand if I want to change the result of the program, I should clear the RAM of the system, but why I have to regenerate the .sof file which is stored in my PC not in FPGA.

thanks
