DSP Builder 8.0 Advanced Blockset / DSP resources

Thanks for the suggestion. I forgot to mention that I had tried this option previously, with no difference in results. I tried stepping up from 200-300 or so, and currently have the value set to 5000. My understanding of this feature is that if the compiler can implement a given multiply function in less than 5000 logic elements, it will....so it should have tried to build the entire design w/ logic, instead of DSP blocks.

I don't know if this has something to do with the fact that all of my multipliers in the design are all essentially the same size (18x18). The Altera docs seem to suggest that this is most useful when you have multipliers of varying sizes (i.e. a 4x4 would use a 9x9 DSP block, when the actual number of logic elements to implement would be a lot less than when trying to implement a 9x9 in logic).
