• Registers are inferred and reported during HDL synthesis.
• The number of Registers inferred during HDL synthesis might not precisely equal the number of Flip-Flop primitives in the Design Summary section.
• The number of Flip-Flop primitives depends on the following processes:
° Absorption of Registers into DSP blocks or block RAM components
° Register duplication
° Removal of constant or equivalent Flip-Flops
