Quartus Fitter Warning

Hi everybody,

I get this warning under Quartus 5.1 : "Performance of this circuit may degrade because the Fitter Delay Information is not loaded"

The FPGA is an ACEX EP1K30TC144-3...

I don't know what this warning is and how to load the correct Fitter Delay Information File ?

Thanks Best Regards.

I had the same problem, the answer from Altera is:

This message is being incorrectly printed. It is a bug that it is printed, and it has been corrected (by removing the message) in Quartus II 5.1 SP1. Ignore the message -- your design functionality and optimization are fine.

Basically our most recent FPGA families (Stratix, Stratix II, Cyclone, etc.) use a different method of storing delay information for optimization during the fitting procedure. This message says that new method is not being used. For APEX that is expected -- it uses a different method, and always will.
