This architecture is based on ancient Indian mathematics, using the "Vertically and Crosswise" sutra to generate and add partial products simultaneously.
The most straightforward implementation resembles grade-school multiplication. It uses an array of AND gates to generate partial products, followed by a network of full-adders and half-adders (e.g., using carry-save adders or Wallace trees) to sum them. These designs are fast (single-cycle) but consume many logic gates. A typical GitHub repository might show a multiplier_8bit_combinational.v module that synthesizes to a large, fully parallel circuit. 8-bit multiplier verilog code github

However, if you want to implement it more manually without using the built-in multiplication operator ( * ), you can do it by shifting and adding, similar to how multiplication is done manually. These designs are fast (single-cycle) but consume many
