can't you download that sof file from your JTAG cable?I would like to make sure if you understand these steps step1: sopc builder you need to make NiosII system. creating *.ptf ( it already exist, right?) step2: QuartusII project compile you need to make QuartusII project to fix your spec in your FPGA. and compile it into *.sof ( it already exist, right?) step3: NiosII project after step1 you can also create NiosII project based on *.sopc file which you have created on step1. step4: download *.sof you can download *.sof file in several way such as JTAG, EEPROM, FPP, etc. easiest way is JTAG. step5: download NiosII program after step4. you can download NiosII program, that may tell you "hello NiosII". so, now you know which step you have missed.
