Instructions
Implement a Basic Counter using JK Flip-Flops
where QB is MSB and QA is LSB.
-
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 (Ori of the
ring counter is 0), to any values of your choice for testing,
by clicking on them.
-
Click on the "Simulate" button to start the clock. The output
bits change at every falling edge of the clock, so you can
watch your circuit at work. The button now reads "Stop":
click on it to stop the clock. "Submit" can be used only while
the clock is stopped.
-
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.
