3.6 Environmental

The environmental section allows the user to define junction temperature (Tj), VDD_CPU_AVS voltage, VDD_MCU voltage, the process corner, and a use case name and description.

  • the PDN / Peak estimate runs with Strong silicon and at either 105°C or 125°C.
  • To save the use case, the user must supply a name for the use case.

GUID-20230330-SS0I-KQP0-RKN7-VCXVKD9KC5SJ-low.png

Note: Impact of User Selected Tj – If the user selects a junction temperature less than or equal to 105°C, the Peak / PDN estimate is computed for 105°C. If the user-selected junction temperature is greater than 105°C, then the Peak / PDN estimate is carried out at 125°C.
