New ContributorThank you for the reply. We intend to always use speed grade 7.
Are you running at maximum clock frequency?
Our design is running only at 20MHz outputted from the built-in PLL.
At your clock frequency does your design timing report show close to zero margin on some logic paths?
The timing report says everything is ok at 125C for the Automotive range, does that not also imply that running the same programming file on an Industrial ranged device up to 100C will also be ok? We are aware that there could be problems running an Industrial device above 100C no matter if the programming file is built for Industrial or Automotive range.
Are you using the full operating temperature range, specifically at the high end where timing performance degrades?
We have ran temperature tests for an extreme case and determined that an Industrial device at 100C should suffice. But the temperature margin was not as big as we would have liked so to have some extra margin we elected to go with the Automotive version. Since we have a lot of trouble acquring Automotive ranged devices we decided Industrial will have to do now too.
As long as speed grade and temperature grade are the same then it is completely safe to reuse a programming file for the devices I listed in the previous post? For example, program a 10M04SCU169A7G programming file to a 10M04SAU169A7G device or a 10M08SCU169I7G programming file to a 10M08SAU169I7G device?
