I don't have one handy to check right now, but I think the .qarlog text file that is generated when you create a .qar would have this info as well. #iwork4intel Replies: Re: How to know what Quartus version was used for compilation from QAR (Project Archive) file? Hi, What you can do is install the latest version of Quartus Prime, open the qar. After that, go to the project directory and look for *.qsf files. Open *.qsf files with notepad, and you able to see which Quartus was original built. Thanks,
