Xilinx Blocks
Figure
Parameters specific to the Mult block are:
∙Multiplier Type: directs the implementation to be either parallel or sequential.
∙Require Maximum Pipelining: directs the core to be pipelined to the fullest extent possible.
∙Use Dedicated
∙Hardware
∙Use Placement Information for Core: allows specification of placement layout shape that will be used when implementing the core in hardware
∙Placement Style: specifies the layout shape in which the multiplier core will be placed in hardware. The Rectangular option will generate a rectangular placed core with loosely placed LUTs. Triangular packing will create a more compact shape, with denser placement of LUTs.
Other parameters used by this block are explained in the Common Parameters section of the previous chapter.
Xilinx LogiCORE
The Mult block always uses Xilinx LogiCORE: Multiply Generator V4.0.
