Altium Add Component To Library From Schematic

Symbols can be copied from the schematic editor into a schematic library, copied between schematic libraries, or created from scratch using the Schematic Symbol Generation Tool or drawing tools.

To create a new schematic library, select the File » New » Library command from the main menus and select the Schematic Library option from the File region of the New Library dialog.

You also can create a schematic library of all components used on the schematic source documents of the active project by clicking Design » Make Schematic Library. This is very useful if you want to create an exact working library, or archive, of your finished design. If there are components with the same library reference but a different internal structure, the Component Grouping dialog will open, with which to specify the parameters to be used for grouping purposes.

All schematic source documents for the active project will be opened, if not already, and a library document (.SchLib) will be automatically created and added to the project. The document will open as the active document in the schematic symbol editor. The library will contain all components used in the design. The created file will appear in the Projects panel as part of the project under the Libraries\Schematic Library Documents sub-folder. The file is initially not saved to the hard disk.

A new schematic component symbol can be created from the active schematic sheet, with the ports on that sheet becoming pins of the component. To do this, choose the Design » Create Component From Sheet command from the main menus or right-click within the main design space - away from design objects - and choose the Sheet Actions » Create Component From Sheet command from the context menu.

After clicking OK in the dialog, the new component will be created, named after the schematic document, in a new Schematic Library document (Schlib1.SchLib). The library will be opened as the active document, and the new component presented as the active component within that library.

Any number of component symbols can be created in a schematic library. To create a new schematic component in an existing library, select Tools » New Component from the main menus or the design space's right-click menu or click the Add button under the Design Item ID region in the SCH Library panel.

Since a new library always contains one empty component, you can also rename Component_1 to get started on creating a component. To do this, select Component_1 from the Design Item ID list in the SCH Library panel then click the Edit button in the panel or double-click Component_1 to open the Properties panel in Component mode. Type the new component name that uniquely identifies it in the Design Item ID field then press Enter.

To remove the current component from the active library, choose Tools » Remove Component from the main menus or right-click in the design space then choose Tools » Remove Component from the context menu. Components can also be deleted directly from the SCH Library panel. Select the component(s) required in the Design Item ID list, then either click the Delete button below the list or right-click then choose the Delete command from the context menu. If using the panel to delete components, multiple deletions can be carried out.

You can add any number of PCB footprint models to a schematic component, as well as model files that are used for circuit simulation and signal integrity analysis. If a component has multiple models (for example, multiple footprints), you can select the appropriate model in the Properties panel when you place the component on a schematic. In terms of sourcing the models, you can create your own or download a vendor's model file from the web. PCB libraries can include any number of PCB footprints.

Wherever possible, Spice models used for circuit simulation (.ckt and .mdl files) are included in the supplied integrated libraries in the Library folder of your Altium Designer installation. If you are creating a new component, you would typically source the Spice model from the device vendor's website. You can also use the XSpice Model Wizard (Tools » XSpice Model Wizard) to create certain Spice model types to add to the component.

You can add models to the current component from the Model region of the design space (click the upside-down arrows/caret symbol on the bottom-right of the design space as shown in the following image).

At the schematic stage, the design is a collection of components that have been connected logically. To test or implement the design, for example, circuit simulation, PCB layout, signal integrity analysis, etc., it needs to be transferred to another design domain. To achieve this, there must be a suitable model of each component for the target domain.

Footprints are linked to the schematic component by adding them in the Parameters region of the Properties panel. Click the Add drop-down then select Footprint to open the PCB Model dialog to configure the footprint.

Models are linked to the schematic component by adding them in the Parameters region of the Properties panel. Click the Add drop-down then select Simulation or Ibis Model to open the respective dialog.

The schematic symbol editor's Model Manager dialog (Tools » Model Manager, or right-click on a component in the SCH Library panel then select Model Manager from the context menu) enables you to view and organize your component models for all components in the active schematic library. For example, you can add the same model to multiple, selected components.

The software's ability to find the model is influenced by the setting that defines where it can look for models. This is the setting just below the model name. The options range from Any, meaning search all available libraries for this model, to Integrated Library or Server, which indicates that the model can only be used from the specified integrated library or Workspace.

When you add a model to a component in the schematic symbol editor, the model is linked; the model data is not copied or stored in the schematic component. This means the linked models must be available both during library creation and when the component is placed on a schematic sheet. When you are working in the library editor, the link from the component to the model information is resolved using the following valid search locations:

For an individual component, parameters are added in the Parameters region of the Properties panel in Component mode. As mentioned, this can be done in the library or once the component has been placed on the schematic sheet.

The default component parameters that are displayed on the schematic are the Designator and Comment. When the design is transferred from the schematic editor to the PCB editor, the Designator and Comment strings are also the default strings that can easily be displayed on the board.

To allow you to display the value of any component parameter on the schematic and PCB, for example, to display the value of a parameter called Capacitance, you can map any component parameter into the component's Comment field using a technique known as string indirection.

Special strings allow the mapping of any parameter to any string. The string can be a component string, a free string placed on the schematic sheet, or a string placed in a schematic template. The parameter can be a component parameter, a document parameter or a project parameter. Refer to the Special Strings to learn more.

Links can be accessed via the context menu when you right-click on the placed schematic component. While any number of named links can be defined, only the first 9 will be available in the Schematic editor's right-click References context menu. Additional named links will not appear in the Schematic editor's Reference menu but will be included in a generated PDF, and will function as live links from the PDF when the component is clicked on in the PDF document (see below).

Links can also be included in a PDF generated from the schematic, either via the Smart PDF feature or a PDF generated from an OutputJob file. The image below shows how the list of component parameters display in the PDF. Any that are URLs can be clicked on to browse from the PDF to that location. Component parameters and links can also be included in a generated PDF by enabling the Include Component Parameters option in the Smart PDF Wizard or OutputJob options generation settings.

Earlier versions of Altium Designer software supported a special parameter called HelpURL. If a component included this parameter, when F1 was pressed while the cursor was hovering over the schematic component or when the References » Help command is selected from the component's right-click menu, the link or the document defined in the HelpURL parameter would be passed to Windows, which would then open the referenced URL or file. This feature is no longer supported. If a component has an existing HelpURL parameter, it should be replaced by a component link as described above.

An ASCII text file (.rep) is generated and opened as the active document. The file includes a total count of the components in the library and lists the component name and a description for each component, if available. 2b1af7f3a8
