The above RTL will infer the following block diagram:
Figure 13-11. MULT18X18MACB Block Diagram
This block diagram can be mapped directly into the sysDSP primitives. Note that if a test point were added between
the multiplier and the accumulator, or two output registers, etc. the code could not be mapped into a
MULT18X18MACB of a sysDSP Block. Therefore, options that could be included in a design are input registers,
pipeline registers, etc. For more Inferring design examples refer to EXAMPLES in the ispLEVER software.
