There are many links describing the virtues and supoort info for using Nios processors but I need to get a license. The time-limited option is useless to me since I need to create an RBF file, whcih cannot be done with a time-limited SOF file.
I cant find a web page to purchase a license and phone numbers are never available so I am at a loss for how to move ahead.
You must obtain a full license for the Intel FPGA IP to generate programming files that you may use for an unlimited time. To obtain a license file, visit the Self-Service Licensing Center or contact your local Intel FPGA representative.

If still your facing problem let me know.
