Can I earn STA analysis under restrict condition?
Basically, the Cyclone4 C-grade devices STA result analyze in 0-85 Celsius degree , voltage min/max and so on .
Can I change above conditions in Quartus ?
For example, Can Quartus change STA analysis condition of temperature from 0-85 Celsius degree to 0-70 Celsius degree?
The timing models are designed for the extremes of operation of the device to guarantee you're meeting timing in all possible valid operating conditions. You can't customize the timing models like this.
Yes, that is the OPN. Thank you for providing this. As mentioned in above comment, you cannot customize the timing model.
Please refer to Recommended Operating Conditions of this document: https://www.intel.com/content/www/us/en/content-details/654714/cyclone-iv-device-handbook-volume-3-chapter-1-device-datasheet.html
