Functional simulation completes successfully. It should include multiplications using different signs (e.g., 7*59, -7*59,
7*-59, -7*-59) (1 point).
Reset_Load_Clear
works on the board. (1 point)
Multiplication works. We will test * , * , * , and * . (1 points)
Consecutive multiplications work, like -1 * -1 * -1 * ... . Reset_Load_Clear will not be pressed between two presses
of Run.

Note - this is only expected to work if the product from the previous multiplication operation can be truncated to
fit into 8-bits without changing the value (e.g. the product is within the range [-128,127])
-1 (16'b1111111111111111) is truncated to (8'b11111111), which is still interpreted as -1, so this is expected to
work for consecutive multiplications.
256 (16'b0000000100000000) is truncated to be 8'b00000000, which is not interpreted as 256, so this is not
expected to work for consecutive multiplications.
Execution cycle responds correctly – exactly one execution per press of the “Run” button. (1 point)
