Electronic Component Reference Designators – Having a system that finds many of the same items in a short amount of time can help you stay organized. Each has a silver drawer and most are arranged with a plate that divides the plates into forks, knives and spoons.
A reference design is a unique identifier on the PCB for each free component or insert in the design. It is a best design practice to number the reference numbers consecutively on the PCB to facilitate locating parts. If the order of the reference marks is preserved in the scheme, the numbering will be uncertain.
Electronic Component Reference Designators
EDA tools are missing a tool that rearranges the location of the reference markers on the PCB. This requires PCB designers to manually annotate during the design process. Manual annotations can take days, so many old patterns have irregular annotations. Let’s take a deeper look at custom global properties and reference designers for PCB design.
Voltage Regulator Part
PCB designers continue to search the Internet to find solutions for their colleagues. The EDA user site directs you to third-party applications that re-annotate design components. However, re-commented scripts have limitations that also require manual manipulation. Learning 3rd party scripts without support information is difficult because guesswork based on trial and error is the only way to run through the tool.
Third-party apps with restrictions may vary by layout. Working with these constraints takes time, which does not guarantee that the location will be marked correctly. Painful hours are spent manually manipulating scripts and manually tagging links. Although the PCB has been re-recorded, the schematic contains the original designation. This is a problem during the life of the board if errors are discovered and the reference design does not match the schematic.
Although user sites offer third-party apps that re-record plans, they all have their drawbacks. Taking the time to read messages can be a tiring task. Also, testing each script is necessary to fully understand how it can help, and this can cause delays in the project.
After spending time with third-party scripts with their shortcomings, designers should consider writing Visual Basic scripts. The help page may indicate that manually writing the ECO file can re-mark it, but this requires many hours of manual attention to reference pointers, components, and new locations on the PCB layout. The learning curve eats up time and designers need more to fill out comments repeatedly. If an error occurs in the last ECO, no error message is displayed to the user.
Circuit Board Parts
It would be great if the annotation tools were available again in the EDA design tools. Any changes to the reference markings will automatically populate the schematic, layout, and bill of materials data. The menu contains notes on target components and free bearings. The drop-down menu contains elegant commands that allow you to select the starting point, the sequential counting direction, and other options.
Note information is tabulated between the old and new marker values. The creation of the file using the relabeling information is shared with the Schema Editor. If you share the information in a file format that the tool understands, other design documents in the repository will return all comments to that location. The schematic symbol matches the PCB layout and debugging from further in the lifecycle is easy.
Altium Designer’s PCB editor has commands to relabel the menu and command structure. Menus and commands are easily accessible thanks to the intuitive design built into the environment. Accessing the Positional Re-annotation dialog allows designers to scope annotations. The scope allows the component’s initial configuration to determine the starting point for relabeling. Knowing that the tool will work sequentially, you can choose directions. There are additional options, such as a re-annotation starting index on a double-sided board, where the reverse page number standard starts with 101 for all markings. If the circuit designer has locked certain components, this comment can be protected from reordering.
The re-annotation tool creates an ASCII text file showing the initial annotation along with the re-annotated benchmarks and data. Text files can be used by Altium Designer’s schematic editor to paste annotations back into the layout using the Annotate Back feature. This allows the schematic and PCB layout to be aligned, reducing stress if the efforts are faulty.

Altium Designer® has elegant and comprehensive tools for annotating reference references. By creating ASCII files, the tool provides global property customization while maintaining consistency across schematics, PCB layouts, and BOMs. Uniform annotations across all documents enable efficient lifecycle management. Comment consistency allows different users to see the same components in the document, ensuring communication about the same parts of the design.
Organize the ingredients with the note-taking tool, which is again at hand. To learn more about our open source software, please contact an Altium Designer expert.
Start your journey to Altium Designer today. “We switched from PADS to Altium Designer because we needed an EDA solution that allowed for real-time collaboration with other R&D teams in our organization, which PADS didn’t offer. In addition to collaboration, we found that Altium Designer was better integrated with SolidWorks as a PADS integration, improving model accuracy and reducing time to market.” Craig Hockenberry, Senior Manager, Engineering, Gibson Brands
