Design won't fit in device

Thanks for the info.

From what I can see in the report, block memory is being used. However, no DSP blocks are being used.

I don't know much about the design at this stage as I've added some logic to it at a very low level, so, I'm finding my way round it too. I don't know what this 'partition_fitter_preservation_level' refers to. I would like to try it completely flattened with no incremental synthesis or anything like that. Right now, I just want it to fit.
