• A simple GUI based tool for school and college students to learn and experiment with BOOLEAN ALGEBRA AND CIRCUITS.

• A ready to use PCB ( 10 x 10 ) on which you can plug components and begin using them by connecting wires.

• Basic components like INPUT, AND, OR, NOT and OUTPUT supported while user can make their own components using built in “Make IC” function.

• “Make IC” saves space, time and makes circuit less cumbersome.

What exactly it is about???

Menu based system for easy user interaction.

Large 10 x 10 PCB gives lots of space to work with.

Status area for prompting important information to user.

Mouse support gives real GUI experience.

AdvancedControl panel lets you manage cells.

SRC gate for setting inputs.(Currently set to 0)

Standard AND gate.(Yellow since one of the pin is open)

Use buttons in control panel to wire the pins.

Status bar prompting user to select source for second pinof AND gate.

Output of gate given here.

Use TOGGLE button to change state of SRC gate.

Circuits can be saved in files for later use and reference.

LOAD button to revive previously saved circuits.

Miniaturise circuits into one IC so that they can be used as one component.

Use IC button to insert previously created IC.

Dialog box requesting for file name to get IC data from.

Type filename and press OK button.

An IC is inserted on the PCB and connected to source and outputs.

IC functioning as a Full adder.

Implementation of a 4 bit add/subtract circuit using IC.

First four pins take the first 4 bit number as input.

Next four pins take the second 4 bit number as input.

Last pin is status flag for operation. HIGH for subtraction and LOW for addition.

Output is a 5 bit number.
