Altium and Eagle are two of the most popular electronic design automation (EDA) software tools used in the industry for designing printed circuit boards (PCBs). Both Altium and Eagle provide users with a range of features for schematic capture, PCB layout, and design rule checking, among others. However, there are some differences in the capabilities and user experience of these two tools that make them better suited to different types of users and projects. In this article, we will explore the main differences between Altium and Eagle and help readers determine which tool is best suited to their specific needs.
What Is Eagle PCB ?
EAGLE (Easily Applicable Graphical Layout Editor) is a flexible and powerful electronics design automation (EDA) application that includes schematic capture, printed circuit board (PCB) layout, and auto-router tools.
EAGLE is a popular choice among many hobbyists, makers, and professionals for designing and laying out PCBs because of its relatively low learning curve, affordability, and wide acceptance in the community. As of my knowledge cut-off in September 2021, EAGLE is owned by Autodesk, a company well known for their powerful design and engineering software tools.
Key Features of EAGLE PCB:
Schematic Editor: This allows you to design your circuits with various components and then connect these components to form a complete circuit design.
PCB Layout Editor: Once the schematic design is complete, EAGLE can generate a board layout where you can place and route the components.
Auto-router: The auto-router feature can automatically route your traces for you based on a set of rules you specify, a useful feature for complex designs.
Library: EAGLE has a vast library of components to choose from when designing your schematic and board.
EAGLE supports various file formats for the output of your design, allowing you to create Gerber files, which are the industry standard for PCB manufacture.
Remember, while EAGLE has many powerful features, like any tool, it has limitations and may not be the best tool for every job.
