Currently, Vivado 2015.2.1 fails to synthesize and gives no error message in the logs. I think the issue is that it can't properly map the BRAM. This is because as I increase the # of devices or # of points processed, it fails to synthesize. Note that in either of these cases, it increases the amount of BRAM needed. I'm unsure if this is correct. I recommend trying to resolve this issue by moving all arrays which scale with the # of points to DDR. This means: y, alpha, data, e.
