Position the cursor so that it is below R1 and level with the base of Q1. Click or press ENTER to anchor the wire at this point. The wire

between the first and second anchor points will be placed.

Position the cursor over the base of Q1 until you see the cursor change to a red connection marker. Click or press ENTER to connect the

wire to the base of Q1.

Note that the cursor remains a cross hair, indicating that you are ready to place another wire. To exit placement mode completely and go

back to the arrow cursor, you would or press again - but don't do this just now.Right-Click ESC

We will now wire C1 to Q1 and R1. Position the cursor over the left connection point of C1 and click or press to start a new wire.ENTER

Move the cursor horizontally till it is directly over the wire connecting the base of Q1 to R1. A connection marker will appear. Click or

press to place the wire segment, then right-click or press to indicate that you have finished placing the wire. Note how theENTER ESC

two wires are automatically connected.

Wire up the rest of your circuit, as shown in the figure below.

The fully wired schematic.

A wire that crosses the end of a pin will connect to that pin, even if you delete the junction. Check that your wired circuit looks like the

figure shown, before proceeding.

When you have finished placing all the wires, right-click or press to exit placement mode. The cursor will revert to an arrow.ESC

If you wish to move any placed components and drag any connected wires with it, hold down the key while moving the component,CTRL

or select .Move»Drag

Nets and Net Labels

Each set of component pins that you have connected to each other now form what is referred to as a . For example, one net includes the basenet

of Q1, one pin of R1 and one pin of C1.

To make it easy to identify important nets in the design, you can add net labels. To place net labels on the two power nets:

Select (shortcut: ). A net label will appear floating on the cursor.Place»Net Label P, N

To edit the net label before it is placed, press key to open the dialog.TAB Net Label

Type in the field, then click to close the dialog.12V Net OK

Place the net label so that the bottom left corner of the net label touches the upper most wire on the schematic. The cursor will change to

a red cross when the net label touches the wire. If the cross is light gray, it means you are trying to label a pin instead of a wire.

After placing the first net label you will still be in net label placement mode, so press the TAB key again to edit the second net label before

placing it.

Type in the field, click to close the dialog and place the net label.GND Net OK

Place the net label so that the bottom left of the net label touches the lower most wire on the schematic. Right-click or press to exitESC

net label placement mode.

Select (shortcut: ) to save your circuit. Save the project as well.File»Save F, S

Congratulations! You have just completed your first schematic capture using Altium Designer. Before we turn the schematic into a circuit board we

need to configure the project options, and check the design for errors.

Setting Up Project Options

All project-specific settings are configured in the Options for Project dialog.

All project-specific settings are configured in the dialog ( ). The project options include the errorOptions for Project Project»Project Options

checking parameters, a connectivity matrix, Class Generator, the Comparator setup, ECO generation, output paths and netlist options,

Multi-Channel naming formats, Default Print setups, Search Paths, and any project parameters you wish to specify. Altium Designer will use these

settings when you compile the project.

When the project is compiled, comprehensive design and electrical rules are applied to verify the design. When all errors are resolved, the

compiled schematic design can then be transferred to the target PCB document by generating a series of Engineering Change Orders (ECOs).

Underlying this process is a comparator engine that identifies every difference between the schematic design and the PCB, and generates an

ECO to resolve each difference. This approach of using a comparator engine to identify differences means you not only work directly between the

schematic and PCB (there is no intermediate netlist file used), it also means the same approach can be used to synchronize the schematic and

PCB at any stage during the design process. The comparator engine also allows you to find differences between source and target files and

update (synchronize) in both directions.

Project outputs, such as assembly, fabrication outputs and reports can be set up from the and menus. These settings are alsoFile Reports

stored in the Project file so they are always available for this project. Alternatively you can set up output options in an Output Job file (

). See for more information.File»New»Output Job File Documentation Outputs

Checking the Electrical Properties of Your Schematic

Schematic diagrams in Altium Designer are more than just simple drawings - they contain electrical connectivity information about the circuit. You

can use this connectivity awareness to verify your design. When you compile a project, Altium Designer checks for errors according to the rules

set up in the and tabs of the dialog. When you compile the project any violations that areError Reporting Connection Matrix Options for Project

detected will display in the Messages panel.

Select to open the dialog (shown in the figure above).Project»Project Options Options for Project

Set up any project-related options in this dialog. We will now make some changes to the , and Error Reporting Connection Matrix
