Last May we bought Quartus and ModelSim (Intel FPGA) licenses.
Hi Siarhei Kazarynau,
First, I would like to apologies for the delayed response.
Second, we're sorry to inform you that the license expire period is only 12 months and not 15 months. Information provided in Intel Website is misprint, is a mistake made in the typing of printed material. We're looking forward to fix that.
Sorry for the inconvenience caused.
