2-Bit Multiplier Practice
Implement a 2-Bit Multiplier using
AND gates and Half Adders
-
Click on components on the left side to add them to the
circuit board.
-
Drag and drop components to move them around, connect them
using wires by dragging your cursor from one endpoint to
another.
-
You can delete components by right clicking on them and
selecting the delete option.
-
You can set the input bits, which are by default 1, to any
values of your choice for testing, by clicking on them.
-
Click on the "Simulate" button after setting the input bits as
per your choice. This will simulate the circuit you built for
the input bits set and will change the output bit values
accordingly, for you to test your circuit.
-
Click on the "Submit" button to submit the circuit once you
think you have built the required circuit.
-
Clicking on "Submit" will display a "Success" or "Failure"
message in the Observations Section according to the
correctness of your circuit. It will also display a Truth
Table verifying your circuit for different input values.
Note: For the 2-bit multiplier, use 4 AND gates for partial
product generation and 2 Half Adders for summation. The 4-bit
array multiplier uses 16 AND gates with Half Adders and Full
Adders. The advanced and the Wallace tree versions also offer
more gates (NOT, OR, XOR, and NAND and NOR in the Wallace tree)
for building your own adder logic. Submit checks the product of
the circuit for all the inputs.
