Published on Online Documentation for Altium Products (https://www.altium.com/documentation) 主页 > Using Altium Documentation Modified by Jun Chu on Apr 26, 2018 Welcome to the world of electronic product development in Altium's world-class electronic design software. This tutorial will help you get started by taking you through the entire process of designing a simple PCB - from idea to outputs files. If you are new to Altium software then it is worth reading the Exploring Altium Designer page to learn more about the interface, information on how to use panels, and an overview of managing design documents. To learn more about a command, dialog, object or panel, press F1 when the cursor is over that item. The Design The design you will be capturing and then designing a printed circuit board (PCB) for is a simple astable multivibrator. The circuit is shown below, it uses two general purpose NPN transistors configured as a self-running astable multivibrator. Circuit for the multivibrator. You're ready to begin capturing (drawing) the schematic. The first step is to create a PCB project. Creating a New PCB Project Main article: New Project

In Altium's software, a PCB project is the set of design documents (files) required to specify and manufacture a printed circuit board. The project file, for example Multivibrator.PrjPCB, is an ASCII file that lists which documents are in the project, as well as other project-level settings, such as the required electrical rule checks, project preferences, and project outputs, such as print and CAM settings. A new project is created in the New Project dialog, as shown below. Create the new PCB project in the required location. Creating a new project: 1. 2. 3. 4. 5. 6. 7. 8. Select File » New » Project from the menus, the New Project dialog will open. Note the list of available Project Types, confirm that PCB Project is selected. Available templates are listed in the Project Templates column, choose . In the Name field, enter Multivibrator. There is no need to add the file extension, this will be added automatically. In the Location field, type in a suitable location to save the project files, or click Browse to navigate to the required folder. Enable the Create Project Folder option, this will create a sub-folder below the folder specified in the Location field, with the same name as the project. Click OK to close the dialog and create the project file in the specified location. The new project will appear in the Projects panel. If this panel is not displayed,

click the Files from the menu that appears. button at the bottom right of the main design window, and select Enabling the Add Project to Version Control option will result in the project's source files being stored in an available SVN repository (click Managed Repositories), and check out the working copies into the folder specified in the Location field. To learn more about version control support, refer to the Version Control and Design Repositories article. If the Managed Project option is enabled, the source files are stored stored in an available SVN repository and the project outputs are stored in an available Altium Vault. To learn more about Managed Projects, refer to the article, The Managed Project and Releasing the Design. These features will not be used for this tutorial.

Adding a Schematic to the Project The next step is to add a new schematic sheet to the project. Add a schematic sheet to the project, name and save the schematic, and save the project. When the blank schematic sheet opens you will notice that the workspace changes. The main toolbar includes a range of new buttons, new toolbars are visible, the menu bar includes new items, and the Sheet panel is displayed - you are now in the Schematic Editor. The floating panel(s) can be closed using the when needed they can be reopened via the buttons down the bottom right of the application. icon at the top right of the panel,

Adding a schematic: 1. 2. 3. Right-click on the project filename in the Projects panel, and select Add New to Project » Schematic. A blank schematic sheet named Sheet1.SchDoc will open in the design window and an icon for this schematic will appear linked to the project in the Projects panel, under the Source Documents folder icon. To save the new schematic sheet, select File » Save As. The Save As dialog will open, ready to save the schematic in the same location as the project file. Type the name Multivibrator in the File Name field and click Save. Note that files stored in the same folder as the project file itself (or in a child/grandchild folder) are linked to the project using relative referencing, whereas files stored in a different location are linked using absolute referencing. Since you have added a schematic to the project, the project file has changed too. Right-click on the project filename in the Projects panel, and select Save Project to save the project. Setting the Document Options Main article: Document Options Before you start drawing your circuit, is is worth setting up the appropriate document options, including the Sheet Size, and the Snap and Visible grids. Document options are conﬁgured for each schematic sheet, set the sheet size as required.

As well as the technique described in the collapsible section below, the Document Options dialog can be opened by double-clicking in the sheet border. Environment options, such as the cursor type, selection color and auto pan behavior are configured in the Preferences dialog (File » System Preferences).

Configuring the Document Options: 1. 2. 3. 4. 5. 6. From the menus, choose Design » Document Options to open the Document Options dialog. For this tutorial, the only change we need to make here is to set the sheet size to A4, this is done in the Standard Styles field of the Sheet Options tab of the dialog. Confirm that both the Snap and Visible Grids are set to 10. Click OK to close the dialog and update the sheet size. To make the document fill the viewing area, select View » Fit Document (shortcut: V, D). Save the schematic by selecting File » Save (shortcut: F, S). Components and Libraries in Altium Designer Related article: More about Components and Libraries This section of the tutorial will explain the two different approaches to working with components (from libraries, or from the Vault). In the following section, you will locate and place the components you need, from the Vault. The real-world component that gets mounted on the board is represented as a schematic symbol during design capture, and as a PCB footprint for board design. Altium Designer components can be: created in and placed from local libraries, or placed directly from the Altium Content Vault, a globally accessible component storage system that contains thousands of components, each with a symbol, footprint, component parameters and links to suppliers. The following component storage options can be used in Altium Designer: Library Type Schematic Library PCB Library Library Package / Integrated Library Altium Content Vault Function Schematic component symbols are created in schematic libraries (*.SchLib), which are stored locally. Each symbol can become a component by adding links to a PCB footprint, then adding component parameters to detail the component's specifications. PCB footprints (models) are stored in PCB libraries (*.PcbLib), which are stored locally. The footprint includes the electrical elements, such as the pads, as well as the mechanical elements, such as the component overlay, dimensions, glue dots, and so on. It can also include a 3D definition, created by placing 3D Body objects, or by importing a STEP model. As well as working directly from the schematic and PCB libraries, you can also compile the component elements into an integrated library (*.IntLib, stored locally). Doing this results in a single, portable library which holds all the models and symbols. An integrated library is compiled from a Library package (*.LibPkg), which is essentially a special-purpose project file, with the source schematic (*.SchLib) and PCB libraries (*.PcbLib) added to it as source documents. As part of the compilation process, you can also check for potential problems, such as missing models and mismatches between schematic pins and PCB pads. The Content Vault is much more than a library. Components are stored in the cloud, accessible from anywhere that has internet access. Content Vault components include: symbol, footprint(s), component parameters, and links to suppliers. They are organized into folders - by manufacturer, or by package type for generics. Accessing Components Components are accessed through the:

Libraries panel for local library components; or through the Vaults panel for Content Vault components. Both of these panels can be accessed via the System menu, click the bottom right of the application to display the menu. button down the The menus provides quick access to the panels. The two panels that are used to access components are shown below.
