Arria 10 - What happens when the TSD temperature exceeds 125 degrees Celcius?

Hi, In my design I am making use of the internal TSD of the Arria 10 FPGA. According to it's specifications it supports a range of -40 to 125 degrees Celcius with an error of +/- 5 degrees. What ha...

Hi Danny,

The Arria 10 Internal Temperature Sensing Diode is a built-in 10-bit ADC circuitry to monitor die temperature.

Basically, TSD is built to monitor die temperature only. Therefore, you need to design your own state machine to reset/switch off the device if TSD temperature exceeds 125°C.
