Modifying TimeQuest Temperature Parameter

The timing models in the Timing Analyzer are fixed and meant for the extremes of device operation. If your design meets timing at those extremes, it will work at the in-range temperature you run at.

Certain devices have additional models if your device is industrial or military grade that go beyond the standard commercial grade models. You can access these models in the operating conditions section of the Timing Analyzer.

The junction temperature setting you probably are referring to is for power analysis, not timing, though I'm not sure why that would cause your design to fail synthesis. What error(s) did you get?

I didn't save the error, but during the fitter stage it said something along the lines of "invalid for selected device"

However, I did notice that there was an option under Operating Settings and Conditions to change the temperature min/max to different values. Not the ones I had manually written but closer. So perhaps there are preset options that are dependent on the device. This did result in the Timing Analyzer running the corner studies at the new values.

It seems to me that you have found the answer. Do you need further help in regards to this case?

No I am all set. Thanks.

I’m glad that your question has been addressed. With that, I will now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.

Best Regards,
