ERRORlace:419 - The design contains 32 BRAM components that are configured as
512x36 BRAMs and 96 multiplier components. The multiplier site adjacent to
the location of a 512x36 BRAM component must remain free because of ressource
sharing. Therefore a device must have at least 128 multiplier sites for this
design to fit. The currently chosen device has only 120 multiplier sites.
RAM is not big enough, So it tried to share the RAM. In order to share the ram, the multipliers close to the ram cannot be used, them you don't have enough multiplier.
Change the device having bigger RAM or more multipliers.
