Running a CYCLONE above its rated temperature

Hi, If I am running a T144 part which is rated for around 80 degrees C what would one expect to happen up to around 120 degrees Celsius? This will be the ambient temperature the device is run...

The maximum junction temperature in maximum ratings is 125 °C, also the maximum recommended junction temperature of devices with extended temperature range. You may want to estimate the power dissipation of your FPGA or better measure it exactly. Check if it gets away with only 5 K overtemperature.

For commercial or industrial devices, there's no guarantee of correct function above their specified 85°C respectively 100 °C junction temperature, but not yet a risk of damage. Similarly no guarantee for any device to survive > 125 °C junction temperature. Your risk to try it though.
