Click again to close this window.

Click on the component (gates, Input & Output) to place it the schematic. There is a limit of 8 inputs and 8 outputs.

Click to place a sub circuit on the schematic. The sub circuit is identified by its circuit id.

To delete the component, just drag it to the dustbin.

Clear the schematic.

View the boolean expression and truth table. They will be displayed only if there are no errors in your schematic and if the schematic has 4 inputs or less. Long Boolean expressions and Truth Tables are usually difficult to interpret.

Share your schematic or embed it in your website or blog (Wordpress). Click the Share button again to close the window.

To update or overwrite your existing schematic. If you are not the owner, you will save into a new schematic.

To save a new schematic. Do this if you want a new schematic by modifying an existing schematic.

Note that if you intend the circuit to be a sub circuit, you must run Expression to check that the circuit is wired up correctly before saving.

To delete the schematic. You can only do this if you are the owner.
