For 7 series devices and Zynq 7000, you can increase the accuracy of SSN analysis by specifying the temperature grade. You must use the correct temperature grade. To add temperature grade information, use one of the following Tcl commands, and then run SSN analysis.

set_operating_conditions -grade Commercial
set_operating_conditions -grade Industrial
set_operating_conditions -grade Military
set_operating_conditions -grade Q-Grade
set_operating_conditions -grade Extended
Note: For UltraScale architecture, temperature grade is included in the part name and automatically incorporated into the SSN analysis.
Tip: To verify operating conditions. use the report_operating_conditions -grade Tcl command. To reset the temperature grade to the default, use the reset_operating_conditions -grade Tcl command.

Following are additional considerations:

  • By default, the temperature grade is based on the device used in the project.
  • When running SSN analysis on an elaborated design, you cannot change the default temperature grade for the targeted part.
  • Operating conditions are also used for power analysis. For information on operating conditions that impact power analysis, see the section Setting Up Power Analysis from the TLD Prompt" in the Vivado Design Suite User Guide: Power Analysis and Optimization (UG907).
