Customer has 3 quartus prime standard licenses and 1 nios II embedded suite license. Are additional seats of NIOSII embedded suite included in the original purchase or would they have to buy more to increase the license count from 1 to 2? (Quartus is not properly releasing their NIOS license and they must restart the LMTOOLs each time for other users to checkout the NIOS license)
Referring to https://www.intel.com/content/www/us/en/programmable/support/support-resources/support-centers/licen..., Nios® II Embedded Design Suite tool is free but you must have a seat license to the Nios II IP core or a development kit to generate an FPGA programming file and flash programming files. There is no license fee for developing software using only the Nios II Software Build Tools for Eclipse
The Nios® II Embedded Design Suite tool itself does not require additional license if customer has Quartus Standard/Pro license. For NIOS II IP, additional license is required if customer wants to compile simultaneously.
