Schematic Capture in Altium

Creating Schematics

Altium’s schematic editor allows you to quickly create and edit schematic diagrams. With its intuitive interface and extensive component libraries, you can easily place components, draw connections, and add labels and annotations.

Hierarchical Design

For complex designs, Altium supports hierarchical schematic design. This allows you to break down your schematic into smaller, more manageable sub-circuits, making it easier to navigate and maintain your design.

Schematic Symbol Editor

Altium includes a powerful symbol editor that lets you create custom schematic symbols for your components. You can define pin properties, graphical representation, and associated models, ensuring that your symbols accurately represent the physical components.

Board Layout in Altium

PCB Layout Editor

Altium’s PCB layout editor is where you’ll spend most of your time designing the physical board. With its advanced routing tools, you can quickly place components, route traces, and define board stackup and manufacturing parameters.

Interactive Routing

Altium’s interactive routing features make it easy to create high-quality board layouts. The software includes tools like push and shove routing, auto-interactive routing, and differential pair routing, which help you efficiently route complex designs while maintaining signal integrity.

3D Visualization

Altium allows you to visualize your PCB design in 3D, giving you a realistic representation of your board before manufacturing. You can check for clearances, analyze mechanical fit, and even export 3D models for mechanical integration.

Library Management in Altium

Component Libraries

Altium includes an extensive library of pre-built components, covering a wide range of parts from various manufacturers. You can easily search and browse these libraries to find the components you need for your design.

Library Creation and Management

In addition to using pre-built libraries, Altium allows you to create and manage your own custom component libraries. You can create schematic symbols, footprints, and 3D models, and organize them into libraries for easy reuse across multiple projects.

Design Reuse

Altium’s design reuse features help you save time and ensure consistency across your designs. You can create reusable design snippets, such as commonly used circuit blocks or board layouts, and easily incorporate them into new projects.

Design Rule Checking in Altium

Design Rule Definition

Altium allows you to define a comprehensive set of design rules to ensure the integrity and manufacturability of your PCB. These rules cover aspects like trace width, clearance, via size, and more, helping you catch potential issues early in the design process.

Real-Time Design Rule Checking

Altium’s real-time design rule checking (DRC) feature continuously analyzes your design as you work, providing immediate feedback on any rule violations. This helps you identify and resolve issues quickly, reducing the risk of costly errors later in the development cycle.

Batch Design Rule Checking

In addition to real-time DRC, Altium also supports batch DRC, which allows you to run a comprehensive check of your entire design before finalizing it. This helps ensure that your design is free of errors and ready for manufacturing.

Simulation in Altium

SPICE Simulation

Altium includes a built-in SPICE simulator that allows you to analyze and optimize your circuit’s performance. You can run various types of simulations, such as DC, AC, and transient analysis, to verify the behavior of your design.

Signal Integrity Analysis

For high-speed designs, Altium offers advanced signal integrity analysis tools. These tools help you analyze and mitigate issues like crosstalk, impedance mismatch, and signal reflections, ensuring that your design meets the required performance specifications.

Thermal Analysis

Altium’s thermal analysis features allow you to simulate the thermal behavior of your PCB, helping you identify potential hotspots and optimize your design for better heat dissipation. This is particularly important for power-dense designs or applications with strict thermal requirements.

Documentation in Altium

Schematic and PCB documentation

Altium allows you to generate comprehensive documentation for your schematic and PCB designs. You can create bill of materials (BOM), assembly drawings, fabrication drawings, and more, all directly from your design data.

Customizable Templates

Altium provides customizable documentation templates that allow you to tailor the output to your specific requirements. You can add your company logo, adjust the layout, and include additional information as needed.

Automated Documentation Updates

One of the key benefits of Altium’s documentation features is that they are automatically updated when you make changes to your design. This ensures that your documentation always reflects the latest version of your schematic and PCB, reducing the risk of errors and inconsistencies.

Collaboration in Altium

Version Control

Altium integrates with popular version control systems like Git and SVN, allowing you to track changes to your design files and collaborate with team members. You can create branches, merge changes, and revert to previous versions as needed.

Design Sharing

Altium’s design sharing features allow you to easily share your designs with colleagues and stakeholders. You can package your design files, libraries, and documentation into a single file for easy distribution and collaboration.

Real-Time Collaboration

For real-time collaboration, Altium offers Altium 365, a cloud-based platform that allows team members to work on the same design simultaneously. This enables seamless collaboration, regardless of location, and helps streamline the design process.
