Cattron purchased a Quartus-II ver.6.0 license many years ago, probably more then 10 years. I would like to view the source files for a FLEX6000 FPGA, but cannot get a temporary license and cannot find the license that was purchased as all the employees involved at the time are no longer working for Cattron. What can be done?
Prior to Quartus Web 8.1 requires license & that you can get it from Legacy License Generator tool but beginning with Quartus Q8.1 Web & future versions of Quartus Web & Lite editions don`t required license.
Please refer the below links & keep a backup first.
just provide the NIC & it will ask for email address,
have a look on old thread,
please let me know if you have any different concern.
