If the Temperature constraint is set to 125C or the Voltage constraint is set to 0.9V, I receive a warning message when launching Timing Analyzer:
"Voltage or Temperature prorating is not available for this device and speed grade."
I realize that prorated data is not yet available for these devices, but 0.9V and 125C represent the worst-case conditions in which the current data in the speeds files was generated from.
A CR has been filed against the tool. To work around this issue, do not specify a Voltage or Temperature in the constraints file.
