Free Schematic Drawing Software and PCB Layout Tools in Altium Designer
Table of Contents
Every circuit board starts with circuit diagrams and schematic sheets. Your schematic capture software takes your component and footprint data and creates an initial layout, which you then route to create a complete circuit board. If you’re just getting started with PCB design, you need a schematic diagram maker that helps you quickly move component data into a new layout. You shouldn’t need to use multiple programs to move from schematic drawing software to layout and bill of materials.
Altium Designer provides the answer to separated schematic drawing software, schematic capture features, and PCB layout tools. Instead of risking incompatibility between free schematic drawing software and PCB layout tools, you need a complete set of design features in one program. When you use Altium Designer, you won’t be blocked by the paywalls you find in free schematic drawing software, and you can prepare your designs for manufacturing.

Your electrical circuit diagrams are like the foundation of a new house. Everything in your PCB is built on top of these diagrams and your schematic sheets. These documents need to detail which components appear in your device, how they must connect to each other, and how your device accesses power and ground. With this document playing such an important role in your printed circuit board, you need the best software that can take your PCB schematic and generate your initial layout.
Your PCB design software should include tools that quickly and easily capture your schematic as an initial layout, with all your connections mapped and your component footprints accurately displayed in a CAD document. Free schematic capture software is hit-or-miss. Some free schematic capture tools interface directly with a layout tool, but this is not always the case. To ensure your design data is synchronized without errors, you need integrated printed circuit board design tool options. With the schematic drawing tools and schematic capture features in Altium Designer, you’ll have everything you need to complete your printed circuit board.
Creating Your Schematics Should Be Easy
Starting from electrical circuit diagrams, you’ll need design tools that help you recreate your circuit diagrams as schematic sheets with verified component symbols and models. A schematic diagram maker in your PCB design software should make it easy to access the components you need without relying on a third-party service. Once you’ve created your schematics with verified components, you need to capture your schematic before creating a printed circuit board layout.
Your schematic tools also need to access data directly from your component libraries and check your device against standard design rules. Free PCB design software oftentimes will leave you without a schematic entry or layout editor for your printed circuit design tool. When all of these features work together, you’ll have the power to design advanced PCBs within a single design environment.
Keep Your Productivity High with Integrated Design Features
Using a schematic capture software tool that interfaces directly with your layout tools ensures your device will comply with basic design rules. Nobody has time to memorize every design rule or constantly rebuild schematics when moving between schematic and layout. A capture tool that interfaces directly with your CAD features automatically places your components where you need them, and you won’t have to build your device twice.
- Creating a schematic diagram is simple when you have the right design features. Altium Designer makes this process easy by giving you the Manufacturer Part Search panel. You can find verified parts quickly and place them directly in your schematic.
- Your circuit board layout software needs data from your schematic, and you’ll need to use a schematic capture tool to get started in a new circuit board layout.
Learn some tips for staying organized in your schematic design software.
- The design structure you use in your schematic maker software can be flat or hierarchical. Altium Designer allows you to use hierarchical schematic design to help you stay organized.

From Schematic Capture to PCB Layout
When you’ve finished creating your electrical circuit diagrams and schematic sheets, you need to capture your design as a blank PCB layout to start arranging components. If you make changes in one document, your changes need to appear in the other document; your layout and schematic need to stay in sync. Use a circuit board design tool with an integrated interface and features if you want to stay productive and keep your design data error-free.
While free schematic capture software and online schematic diagram maker software offer limited feature sets, Altium Designer provides everything needed to create high-quality layouts without an external design tool. This all happens with a schematic capture feature integrated alongside your schematic editor and PCB layout editor. Everything from electrical circuit diagrams to your PCB layout stays synchronized with Altium Designer.
Keeping Your Schematic and Layout Synchronized
Free schematic capture software that works as a standalone tool can’t keep your design data in sync. Free schematic drawing software also can’t provide you with verified components, and you’ll need to import component data from a third party. The best PCB design software doesn’t just synchronize your schematic and layout, it enforces all harmony across all of your design data.
With so many components available on the market, you need a schematic drawing system that makes it easy to add components to your printed circuit board schematic and layout. With Altium Designer, you can easily find existing components and add new component data to your libraries. Free schematic drawing software doesn’t give you these features and can’t provide you with verified components directly from manufacturers.
- Once you’re ready to create your PCB layout data and prepare for fabrication, the data from your schematic diagrams and netlists are used in your layout tools. Altium Designer simplifies this process, and you won’t need to export and import multiple netlists to create your fabrication instructions.

- Using the right component library structure in your schematic design software helps you prevent data errors when you create your PCB layout.

- Once you have drawn up your initial schematic diagram, you can instantly translate your schematic to a board layout with separate capture software.
