Binary To Bcd Verilog Code Link
(8‑bit input): ~30‑40 LUTs in an FPGA (e.g., Xilinx/Altera).

Best for small bit widths (e.g., 8-bit). It is fast but can become area-heavy as the number of bits increases. (8‑bit input): ~30‑40 LUTs in an FPGA (e

For the generate‑based combinational version, simply increase the input width and loop count.
