    Quick answer - The programmable elements inside a FPGA called CLB = Confiurable Logic Blocks.

    If you look inside a CLB will it consist of LUTs = Look Up Table and Flip-Flops/Latches.

    The LUTs and F/F's organized in Slices which means that those elements shares connections in order to utilized fast carry chain.

    Slices in FPGA

    Common components such as flip-flops, LUTs, block RAM, and multiplexers make up the basic logic structures on a FPGA.
    A Collection of these basic structures is referred to as a slice or a configurable logic block (CLB). The definitions of a CLB and a slice are specific to each device family.

    how do you reduce the number or slices?

    How do you reduce the number of slices used. What should i be looking to change.
