  • Description: Multiply two 8-bit numbers, get a 16-bit result.
  • GitHub repository
  • Clock: 0 Hz

How it works

Do synchronous reset first, then on each rising clock edge...

Clock in each of two 8-bit values, one nibble at a time (high to low).

Then clock out a 16-bit value, one byte (via result) at a time (high to low).

How to test

After synchronous reset, expect result output to be 0.

Set nibble to a value of your choice, then pulse the clock.

Repeat 3 more times.

Then pulse the clock 1 more times, each time expecting to get a byte at the output result.
