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 -gradeTcl command. To reset the temperature grade to the default, use the
reset_operating_conditions -gradeTcl 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 this link in the Vivado Design Suite User Guide: Power Analysis and Optimization (UG907).
