    Description

    Yes, the Stratix® III timing model for the I4 industrial speed grade at 100C and -40C has been updated. The I4L and I3 industrial speed grade timing models have not changed. This update changes the low speed tile delays in the Stratix III I4 Quartus II model, which may impact your static timing analysis and fitting results.

    If your design works correctly in your hardware system, we recommend no action be taken. However, a patch to update the timing model is available, and you may choose to rerun your current Stratix III I4 industrial design with the Quartus II version 9.0 SP2 plus patch 2.74 if there are any indications of hardware or timing failures.

    You can download the appropriate patch 2.74 to update the Stratix III I4 timing model in the Quartus® II software version 9.0 SP2 using the following links:

    The updated timing model is also incorporated in the Quartus II software version 9.1.
