Combinational (synthesizable, simple):
Simple shift-add architecture using full adders and half adders. 8bit multiplier verilog code github
Different designs prioritize speed, area, or power consumption. Here are the three most common types found in Verilog repositories: Compile: iverilog -o multiplier_sim multiplier
