Junction temperature and cooling solution settings for 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.

Junction temperature and cooling solution settings for power analysis are used by the 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 Intel® 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 Intel® 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 Intel® 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.
