Found 16-bit register for signal <PHA_ACC6>. Found 512-bit register for signal <ram_data>. Found 16-bit register for signal <trig>. Found 16 1-bit 2-to-1 multiplexers.INFO:Xst:738 - HDL ADVISOR - 512 flip-flops were inferred for signal <ram_data>. You may be trying to describe a RAM in a way that is incompatible with block and distributed RAM resources available on Xilinx devices, or with a specific template that is not supported. Please review the Xilinx resources documentation and the XST user manual for coding guidelines. Taking advantage of RAM resources will lead to improved device usage and reduced synthesis time.

When assembling slices, Map gives priority to combine logic that is related. Doing so results in the best timing performance. Unrelated logic shares no connectivity. Map will only begin packing unrelated logic into a slice once 99% of the slices are occupied through related logic packing. Note that once logic distribution reaches the 99% level through related logic packing, this does not mean the device is completely utilized. Unrelated logic packing will then begin, continuing until all usable LUTs and FFs are occupied. Depending on your timing budget, increased levels of unrelated logic packing may adversely affect the overall timing performance of your design.Mapping completed.See MAP report file "top_map.mrp" for details.Completed process "Map".Mapping Module top . . .
