...     Tutorial 1: The Basics

In this tutorial you will learn basic circuit-building techniques. We will build and test a simple 3-input circuit to compute O = ~A + (B C). We will use 3 simple switches and one simple bulb. We will then save the project and export it to XML, then reload and import it. Finally, we will use the circuit as a subcircuit.

Refer to Adding, Selecting, Copying, Moving, Deleting and Connecting Components to learn how to place components on the circuit board and to connect them.

1. Add 3 switches ( ), 1 bulb ( ), 1 OR-gate ( ), 1 NOT-gate ( ), and 1 AND-gate ( ) to the circuit board, as shown.

   

2. Connect the components as shown.

   

3. Right-click each of the switches, select Add/Delete Label and label them, A, B and C, respectively. Do the same for the bulb and label it O.

   Now click switch C to test the circuit.

   

   Try different switching patterns and observe the result.

4. Select File | Save Project ( ) and save the project as Proj1.cct.
5. Select File | Export XML Project and export the project as Proj1.xml.
6. Select File | New Project
7. Select File | Load Project ( ) and choose Proj1.cct.
8. Select File | New Project
9. Select File | Import XML Project and choose Proj1.xml.

10. Select File | New Project
11. Select Elements | Add Card ( ) and choose Proj1.cct.
12. Click on the circuit board. The card should appear.
13. Add a switch bank ( ) and click the spinner to create 3 switches. Add a single bulb

    

14. Swipe across the pins of the switch bank and connect them to the card's input pins. Connect the card's output pin and connect it to the bulb. Click the switches to see the resulting output.

           

15. Double-click the card to splash-view its structure.

    

16. Click Proj1 in the subcircuit window.
17. Right-click Proj1 in the subcircuit window and select Export proj1 as chip.
18. Select File | New Project
19. Select Elements | Add Chip ( ) and repeat steps 12 - 14 with the chip.
