Parent page: Creating a New Component
Before saving a Workspace Library component defined/edited in the Component Editor (in its Single Component Editing or Batch Component Editing mode) to the connected Workspace and making the component be available for use in designs, it is essential to make sure that this component meets the requirements in accordance with the configured settings. When you attempt to save a component back to the Workspace, the Component Editor runs a validation – a Component Rule Check. This feature can also be run at any time, manually, by choosing the Tools » Component Rule Check command, from the main menus. Be sure to have saved your component locally (File » Save) before you do.
The Component Rule Check command is also available from the editor's main File menu and from the component entry's right-click menu in the Projects panel.
Just as a board project has the validation process to detect any violations, the Component Editor has a Component Validator. Any violations that are found are listed in the Messages panel.
Detecting issues with a component prior to saving to the Workspace. Shown here is running the Component Rule Check command from the Component Editor in its Single Component Editing mode. Hover the cursor over the image to see running the command from the Component Editor in its Batch Component Editing mode.
The Component Validator tests for an array of potential issues with the component and its defined models – both hardwired tests, as well as a range of violation types that can be user-defined at the global level.
The following hardwired validation checks all carry a report mode of 
:
Component not referencing any models
Summary
This violation occurs when a component being defined in the Component Editor has no added links to the domain models (Symbol, Footprint(s), Simulation Model(s)).
Notification
A notification will be displayed in the Messages panel in the following format:
Component is not linked to any models.
Recommendation for Resolution
- In the Component Editor in its Single Component Editing mode, add links to saved (or created on-the-fly) domain models using the Model region of the editor, for use by the component.
- In the Component Editor in its Batch Component Editing mode, add links to saved domain models listed in the Model Links region of the editor, for use by the component.
Folder path not specified for component
Summary
This violation occurs when a folder in the target Workspace where a component being defined in the Component Editor should be saved is not specified.
Notification
A notification will be displayed in the Messages panel in the following format:
Folder path not specified for component <ItemID>
where:
- ItemID is the ID used for the component in the Workspace.
Recommendation for Resolution
- In the Component Editor in its Single Component Editing mode, use the Folder field in the Component to specify a folder in the target Workspace where the component will be saved to. To manually specify a target folder, click the
button to access the Choose Folder dialog. Browse to, and choose an existing folder, or create a new one on-the-fly.
- In the Component Editor in its Batch Component Editing mode, use the FolderPath field (in the Component column group) in the component definition region of the editor to specify a folder in the target Workspace where the component will be saved to. To manually specify a target folder, click once inside the FolderPath field for a component to reveal the
button, and click to access the Choose Folder dialog. Browse to, and choose an existing folder, or create a new one on-the-fly.
Component not having a unique Id
Summary
This violation occurs when the Item ID of a component being defined in the Component Editor is the same as the Item ID of another item in the connected Workspace.
Notification
A notification will be displayed in the Messages panel in the following format:
Duplicate Component Id: "<ItemID>"
where:
- ItemID is the ID used for the component in the Workspace.
Recommendation for Resolution
- In the Component Editor in its Single Component Editing mode, use the Id field in the Component region to specify another ID which is unique for the connected Workspace content.
- In the Component Editor in its Batch Component Editing mode, use the Item ID field in the Component column group of the component definition region to specify another ID which is unique for the connected Workspace content.
Note
This violation typically occurs when an automatically assigned Item ID value of a component is manually overridden. For a new component created through the File » New » Component command or the Components panel, this field is populated in accordance with the component template defined for the component type chosen in the Create new component dialog. Where a template does not exist, or where the <Undefined> entry is chosen in the dialog, a default naming scheme is used; CMP-{00000}. For a new component created through the Explorer panel, this field is populated in accordance with the default naming scheme specified for that component's parent folder. If the parent folder has a component template attached, then defined Component Naming will be brought in from that template. The software will automatically assign the next available unique ID, based on that scheme, having scanned the entire Workspace and identifiers of existing content.
User-definable checks are configured on the Data Management – Component Rule Checks page of the Preferences dialog.
User-definable violation checks that can be configured as part of global preferences, for use with the Component Validator.
Any of the hardwired tests that fail, or user-defined checks at a level of Fatal Error, will prevent saving of the component to the Workspace.
The default settings of the user-defined checks may not suit your components and, therefore, it is important to become familiar with the options and how to configure them to suit your designs. Information about each user-defined error check can be found below.
