Junction temperature and cooling solution settings for PowerPlay power analysis
Allows you to specify operating parameters pertaining to junction temperature, cooling solution, and circuit board thermal model. The following settings are available:
- Specify junction temperature— Allows you to specify a junction temperature in degrees Celsius. The specified junction temperature must be within the range specified in Junction temperature range.

Settings:on | off *default
Settings:
default = 25 |
- Auto compute junction temperature using cooling solution— Directs the Quartus® Prime software to calculate junction temperature based on a cooling solution.

Settings:on | off *default |
- Ambient temperature— If you selected Auto compute junction temperature using cooling solution, allows you to specify an ambient temperature in degrees Celsius.

Junction temperature and cooling solution settings for PowerPlay power analysis are used by the PowerPlay Power Analyzer. These settings do not affect timing analysis.
If a specified ambient or junction temperature is above the allowable junction temperature range for the device, a warning message appears and the Quartus® Prime software uses the maximum allowable temperature in power analysis; if a specified ambient or junction temperature is below the allowable junction temperature range for the device, a warning message appears and the Quartus® Prime software uses the minimum allowable temperature in power analysis.
If a specified ambient or junction temperature is outside the user-specified junction temperature range, but within the allowable junction temperature range for the device, the Quartus® Prime software uses the specified temperature and a warning appears in the Messages window informing you that the specified temperature is outside the range you specified in Junction temperature range.
