Now came the ritual. The integration. He changed the module name to match his design and instantiated the multiplier within the ALU case statement.
He rubbed his eyes, staring at the waveform simulation on his screen. It was a mess of red lines and undefined X states. His project—a simple RISC processor core—was stalling at the arithmetic logic unit (ALU). He needed a multiplier. Not the simple * operator that synthesis tools allowed for prototyping, but a real, gate-level structural implementation. He needed to see the bits move. 8-bit multiplier verilog code github
Too readable.
The simplest form, using the * operator. Modern synthesis tools like Vivado or Quartus automatically map this to efficient DSP slices on an FPGA. Now came the ritual
