NIOS II Gen2 License - NIOS II Gen2 License Hi, Do we need to purchase any license for NIOS II gen2 economy/fast cores? Replies: Re: NIOS II Gen2 License Hi, No license is needed for using NIOS tool but you must have a license to the Nios II IP core or a development kit to generate an FPGA programming file and flash programming files. However, you do need a license for NIOS ll/f and IP will be in floating if you are using floating license: https://www.intel.com/content/www/us/en/programmable/support/support-resources/support-centers/licensing.html
