  • A thermal forcer—or alternatively, you can use a temperature chamber—covered and sealed the FPGA and forced the temperature as per the set temperature point.
  • During this test, the FPGA remained in unpowered condition to avoid it from generating heat.
  • The soak time for each temperature test point was 30 minutes.
  • The settings on the evaluation kits used the default settings from the manufacturers.
  • After the setup, steps in Offset Compensation were followed for data collection and analysis.
