Compilation Dependent Behavior

Yes I did run the analysis and the estimation difference was huge, but unfortunately I don't have much of a choice for the application since the hardware has already been determined. I am left at the discretion of the requirements and what I have been given to work with.

In one of my other posts I have added some additional logic between the PCI bus and the memory controllers, and oddly enough the failure rate dropped extremely. From what I can tell, two of the memory controllers now work all of the time, and the other two memory controllers fail still, but work most of the time (i.e. 1/100 write seems to fail, which is still not acceptable, but certainly an improvement.)

I was wondering if there was a straightforward tutorial on assigning path assignments in the Timing Wizard?

I have a feeling that the failures are not due to an output-to-memory issue like I did initially but more of an internal timing issue.

Thank you all again.
