Migrating Existing Libraries to Your Connected Workspace in Altium Designer

Altium Designer, in conjunction with your managed content server, provides a streamlined process to quickly migrate your existing libraries to that Server. The GUI to this process - the Library Migrator view - presents an intuitive flow that takes selected libraries, and migrates them to the managed content server to which you are actively signed in. Catering for all types of libraries, relating to older component management methodologies - SCHLIB, PCBLIB, INTLIB, DBLIB, SVNDBLIB - the Library Migrator is the perfect solution to quickly building your company's set of managed components, and the many benefits that such components enjoy (high-integrity, lifecycle management, centralized storage and management, where-used functionality, ease of design reuse). And while the migration process can be configured - giving you enhanced control over how that migration is performed - you can accept the default settings and set the migration in motion within a matter of clicks.

While access to the Library Migrator is available in Altium NEXUS, should you wish to access an unmanaged library to make pre-migration tweaks, or access the Available Libraries list, you will need to enable the use of legacy, unmanaged component management methodologies, as well as the Libraries panel. Use of unmanaged content is disabled by default in Altium NEXUS, as it is not recommended. You can restore this functionality by enabling the following options in the Advanced Settings dialog - accessed by clicking the  button, on the System - General page of the Preferences dialog:

• Legacy.UnManagedLibraries
• Legacy.LibraryPanel

You will need to restart Altium NEXUS for the changes to these settings to take effect.

What gets Migrated?

All information that is present in an original source library is migrated, in order to arrive at a folder of Unified Components (managed components that have assigned part choices), with all referenced domain models (schematic symbols, PCB footprints, Simulation Models) and parametric information. Component templates can even be created, and used to create those managed components. And if your original components have multiple PCB footprints defined, you can rest assured that the Library Migrator will bring those models across, and keep the current default footprint too.

And if you only work with PCB libraries - your only concern is PCB layout - then the Library Migrator supports migration of just those libraries.

And while migration may seem daunting, the defaults have been defined to enable you to get your collection of managed components without having to change a thing - start the process and design with the fruits of the Migrator's labor. The system conducts and handles a number of validations, for example to ensure no duplicate IDs for the resulting managed components, or to ensure no duplicate models or component templates are created, and that such entities are reused across (linked to) components where needed. And if issues do arise, the system flags them, with suggestions on how to resolve those issues, aiming to get the migration back on track as quickly, and as smoothly as possible.

Accessing the Library Migrator

The migration functionality is delivered through a purpose-made extension - the Library Migrator extension.

The Library Migrator extension.

The Library Migrator can only be accessed, provided the Library Migrator extension is installed as part of your Altium Designer installation. This extension is installed by default when installing the software, but in case of inadvertent uninstall, can be found back on the Purchased tab of the Extensions & Updates page (accessed by clicking on the  control at the top-right of the workspace and choosing the Extensions and Updates command from the menu).

The graphical interface to the component migration process is the Library Migrator view, which is accessed by choosing the File » Library Migrator command from the main menus (from any document editor).

The Migration Process

The migration process is a staged flow, with the entries on the left-hand side of the Library Migrator view showing you at-a-glance, which stage you are currently at.

Stage 1 - Select Libraries

This stage of the release process is where you specify the libraries that you wish to migrate. Library types that can be migrated are:

• Schematic Library (*.SchLib).
• PCB Footprint Library (*.PcbLib).
• Integrated Library (*.IntLib)
• Database Library (*.DBLib).
• SVN Database Library (*.SVNDBLib).

By default, all supported libraries found within the Available Libraries for the active/focused project, will be loaded and enabled ready for migration - so all project libraries, installed libraries, and libraries found along specified search paths.

You can view the Available Libraries for the active/focused project in the Available Libraries dialog - accessed by clicking the  button at the top-left of the Libraries panel.

Supported libraries, found in the list of libraries available to the active/focused project, will be added and selected for migration by default.

You can also add further libraries to the list of libraries to be migrated. This can be done in a couple of ways:

• Drag and drop selected libraries directly from your Windows File Explorer onto the Library Migrator's main library listing area. The libraries will be added to the migration list.
• Click the  button, then use the Open dialog to browse to, and select, the required libraries. After clicking Open, the libraries will be added to the migration list.

To successfully migrate a Schematic Library (SCHLIB) to the server, the Library Migrator must be able to locate Models that are linked to that library, such as component footprints in a corresponding PCB Library. This requires that the model source library is specified in the Schematic Library, and the libraries are located in the software's default library path.

With the libraries required to be migrated selected in the list, click the  button at the bottom-right of the view.

Stage 2 - Configure Migration

This stage of the migration process loads the component list ready for migration, and presents optional controls for configuring the migration.

An example of accessing the controls to configure the migration for a specific library, in this case Crystals.IntLib.

The page is divided into the following two key regions, with a third region dedicated to providing a preview of the resulting folder structure that will be created/used.

Source Libraries

This region lists all of the libraries involved in the migration process. Select a library to access and configure settings specifically concerned with the migration of that library's components.

Component Settings

This region of the page presents all settings that can be configured, specifically for the selected library.

The following collapsible sections look at the various settings available:

With migration settings configured for libraries as required, click the  button at the bottom-right of the view.

Stage 3 - Preview

This stage of the migration process provides a preview of the content that will be created in the managed content server, flags any issues, and allows any last minute changes to component types, parameter names, and parameter types.

The Preview stage of the migration process allows you to see, in greater detail, what exactly will be created in the Server as a result of the migration.

The preview is essentially divided into two key regions:

Folders

This region, on the left, presents the folder structure that will be created/used in the Server, and is the same as the Folder Structure Preview presented when configuring the migration in the previous stage of the process. Click on a folder entry to load its components in the region on the right.

Components

This region, on the right, presents the components that will be created in the selected Server folder. The region is further sub-divided into two:

• Upper Region - presents a listing of all Component Items that will be created in the Server. For each component, its ID, Comment, Description, and Component Type are shown, along with all user-defined parameters from the original source library. Should you need to change the Component Type for one or more components, select them in the list, then right-click and choose the Change component type command from the context menu. The Change Type dialog will appear. Use this to enter a type directly, or click the  button to access and use the Component Type dialog with which to do so.

Similarly, you can change attributes of user-defined parameters on-the-fly too. To rename a parameter, right-click over the column for that parameter and choose the Rename parameter command from the context menu. Use the Rename Parameter dialog that appears to change the name as required. And if you need to change the parameter's type (to make it unit-aware), choose the Change parameter type command from the context menu. Set the required type from the Change Type for Parameter dialog accordingly.

The components that will be created in a folder, along with their parametric information. Commands on the right-click context menu cater for last minute changes, such as
changing the type of a parameter (shown), renaming a parameter, and changing the component type.

• Lower Region - presents information relating to the chosen component in the upper region, across the following tabs:
  • Details - lists any issues found for the component, such as footprint model not available in the source libraries, or if pin mapping information is defined for a linked simulation model, a caution that this is not supported for migration. See Previewing Issues for more information.
  • Part Choices - if supplier information was defined for the original source component, through supplier link parameters (Supplier n/Supplier Part Number n) or text-based manufacturer/manufacturer part number parameters, then this tab will list those supply chain solutions.

Example supply-chain solution associated to the selected component, that will becoame a defined part choice for the created Component Item.

• Models - this tab lists the domain models that will be referenced by the created Component Item (Schematic Symbol, PCB Footprint Model, Simulation Model). All of these models will be items in the Server in their own right. Models may be created specifically for the component, under sub-folders, or may be referenced from elsewhere in the Server, if already created (or going to be created). The system avoids duplication of models, instead reusing a model between multiple components.

Example models that will be referenced by the selected component.

Previewing Issues

While previewing the components and related entities that will be created in the Server, the Library Migrator also flags any issues. Two graphical icons are used to do this:

•  - an error. A problem with the original component in the source library will lead to unsuccessful migration of the indicated component. An example might be that the referenced footprint model is not available.
•  - a warning, or caution. The migration of the component will proceed, but not fully for some reason. An example is the caution that the migration of pin mapping data is not supported, or that simulation parameters will not be migrated as component parameters.

Issues are flagged in the following places:

• At the folder level, to indicate there are issues with components therein.
• At the component level, with the appropriate icon to the left of a component's entry.
• At the detailed level. Issues are listed on the Details tab, when the affected component is selected.

Flagging issues and providing details of those issues.

Once you are comfortable that all is in order, you can proceed with the actual migration itself, by pressing the  button at the bottom-right of the view.

Stage 4 - Migration

This stage of the process involves the actual migration of the components to the Server. The system performs a final set of checks, including:

• If there are any components with errors (), you will be alerted that those will be skipped (and how many). You are given the option to cancel the migration (and resolve those issues), or click to continue with the migration of those components remaining, and that can be migrated.
• If you have components referencing simulation models with defined pin mapping, you will be alerted that migration of pin mapping is not supported. Again, you can cancel the migration at this point, or click to continue.
• If there are components with defined simulation parameters, you will be alerted that such parameters will not be migrated as component parameters. Again, you can cancel the migration at this point, or click to continue.

The migration process then proceeds, with progress displayed graphically through a progress bar, and in detail through a report that shows you exactly what is happening at each point in time. In addition, the Elapsed Time is shown, along with an estimate of the Remaining Time until the migration process fully completes.

An example migration in action. You are kept informed of progress and given detailed information of what the Library Migrator is doing at every stage of the process.

The initial flow of the process involves the following elements being created in the Server:

1. The general folder structure is created.
2. The component template folder is created, that will house all Component Template Items created for the source libraries. This is: Managed Content\Templates\Component Templates.
3. Component types for each library involved in the migration are created, where needed.
4. Component templates for each library are then released into Component Template Items, within the component template folder.

For each source library included in the migration process, the following flow is then followed:

1. The component list to skip is selected - those components that cannot be migrated due to an existing issue.
2. The component list to migrate is selected - those components that can be migrated without issue.
3. The library folder structure is created within the Server, consisting of a component folder and folders for each involved model type. Model folders are created once under a generic sub-folder named Models.
4. The model libraries are then released, creating the Symbol Items, Footprint Items, and Simulation Model Items (only where existing models are not available for reuse).
5. The Component Items themselves are then created.
6. Folder attributes are then set for the various folders.
7. A saved search item is created.
8. Supply chain information is then migrated, creating the associated part choices for the released components.

The final act of the migration process is to create an 'Item Manager rule'. This creates the necessary auto-mapping, so that once your components have been migrated to the Server, you can then migrate your existing designs to use those components, using the Item Manager, without any additional effort.

Stage 5 - Report

This is the final stage of the process, providing a detailed report (essentially the completed report that could be seen in real-time during the Migration stage).

The final, detailed report for the migration.

The right-click context menu provides the following commands:

• Export to file - use this command to export the entire report. The Save As dialog allows you to specify where, and with what name, the report is saved. Supported formats for export are: Excel files (*.xls; *.xlsx), HTML files (*.html), PDF files (*.pdf), Text files (*.txt), and CSV files (*.csv).

An example migration report, exported into Excel format.

• Copy to clipboard - use this command to copy the currently selected rows of the migration report, to the Windows clipboard, for pasting into an external application.

An example illustrating a portion of a migration report copied to the clipboard, then pasted into Notepad to be saved as a txt file.

That's it - with your components migrated, you can close the Library Migrator view. Now you can enjoy designing with your new set of managed components.

Browsing Migrated Components

Browse your migrated components from the Explorer panel - your portal to your active managed content server.

By clicking the  button, at the bottom-right of the view when the Library Migrator is presenting the migration report, you can quickly gain access to the Explorer panel. You will be taken to the first component, in the first migrated library.

And don't forget the Component Templates that were created, and which are used in the creation of those components. These can be found, as mentioned previously, in the Managed Content\Templates\Component Templates folder.
