14.x PlanAhead - SSN Report Noise Analysis Report does not function for Spartan-6Q parts


In 13.4 the option to Report Noise Analysis for Spartan-6Q is not present.

In 14.1 the option to Report Noise Analysis for Spartan-6Q is present but does not generate the report.

SSN reporting for a corresponding non-Q Spartan-6 part functions as intended.


SSN analysis is not supported for the Spartan-6Q parts and the option should not have been enabled in PlanAhead tool.

The best solution to get usable SSN information for a Spartan-6Q design is to run SSN analysis while targeting the corresponding non-Q Spartan-6 commercial part. Then de-rate the commercial part by 20% and you should get a similar margin.
