Step 7: Select Place > Auto Wire > Two Points from the menu.

Wiring Connections Automatically

Step 8: Click the bottom terminal of V2. Move the cursor to the ground junction.

Note: A guideline will connect the intended pins.

Step 9: Click to automatically create a connection between V2 and ground. Right-click and select End Mode (Esc).

Placing Net Aliases

Step 10: Select Place > Net Alias from the menu, the Net Alias button on the toolbar, or press N on the keyboard.

Note: Using net aliases make it easier to understand simulation results.

Step 11: Name the alias Q1B and click OK.

Step 12: Click to place the alias on the base of Q1.

Step 13: Right-click and select Edit Properties or press N again on the keyboard.

Step 14: Name the alias OUT and click OK.
