Introduction to System Designing with Altium

System designing is a crucial aspect of electronic product development, and Altium Live 2022 introduced a powerful feature called Multi-Board Project that streamlines the process. This article will explore the concept of system designing, the benefits of using Multi-Board Project in Altium, and provide a step-by-step guide on how to utilize this feature effectively.

What is System Designing?

System designing is the process of creating a complex electronic system by breaking it down into smaller, interconnected subsystems or modules. Each module is designed to perform a specific function and interact with other modules to achieve the overall system functionality. System designing involves the following key aspects:

1. Defining system requirements and specifications
2. Partitioning the system into functional modules
3. Designing individual modules and their interfaces
4. Integrating modules and verifying system functionality
5. Optimizing system performance and reliability

The Importance of System Designing in Electronic Product Development

Effective system designing is essential for developing high-quality, reliable, and cost-effective electronic products. Some of the key benefits of system designing include:

1. Modularity: Breaking down a complex system into smaller modules makes the design process more manageable and allows for easier maintenance and upgrades.
2. Reusability: Well-designed modules can be reused in future projects, reducing development time and costs.
3. Scalability: Modular designs enable easier scaling of the system to meet changing requirements or market demands.
4. Collaboration: System designing promotes collaboration among team members, as each module can be designed and tested independently.
5. Improved reliability: By focusing on individual module functionality and interfaces, system designing helps identify and address potential issues early in the development process, resulting in a more reliable final product.

Multi-Board Project in Altium Live 2022

Altium Live 2022 introduced the Multi-Board Project feature, which revolutionizes the way designers approach system designing. This feature allows users to create and manage multiple interconnected PCBs within a single project, enabling seamless integration and synchronization of design data across all boards.

Benefits of Using Multi-Board Project in Altium

1. Unified design environment: Multi-Board Project provides a centralized platform for managing all aspects of a multi-board system, including schematic capture, PCB layout, and documentation.
2. Synchronized design data: Changes made to one board are automatically propagated to other boards in the project, ensuring consistency and reducing the risk of errors.
3. Simplified interface management: Multi-Board Project streamlines the process of defining and managing inter-board connections, making it easier to ensure proper connectivity between modules.
4. Enhanced collaboration: Team members can work on individual boards simultaneously, with real-time updates and version control for efficient collaboration.
5. Improved design visualization: Multi-Board Project offers 3D visualization tools that allow designers to view the entire system and check for mechanical fitment and clearance issues.

Step-by-Step Guide to Using Multi-Board Project in Altium

1. Create a new Multi-Board Project: In Altium Designer, go to File > New > Project > Multi-Board Project. Specify the project name and location, and click OK.
2. Add boards to the project: Right-click on the project in the Projects panel and select “Add New Board”. Repeat this process for each board in your system.
3. Define inter-board connections: Use the “Connections” view in Altium to specify the interfaces between boards. This can be done by creating

“Net Labels” on each board and associating them with the appropriate connector or pin.
4. Design individual boards: Work on each board’s schematic and PCB layout independently, while ensuring that the inter-board connections are maintained.
5. Synchronize design data: As you make changes to one board, Altium will automatically propagate relevant updates to other boards in the project. You can also manually synchronize design data by right-clicking on the project and selecting “Synchronize All Documents”.
6. Verify system integration: Use the 3D visualization tools to check for mechanical fitment and clearance issues, and ensure that all inter-board connections are properly aligned.
7. Generate manufacturing outputs: Once the system design is complete, generate manufacturing files (e.g., Gerber, BOM, pick and place) for each board in the project.

Real-World Application: Designing a Multi-Board IoT System

To illustrate the power of system designing using Multi-Board Project in Altium, let’s consider a real-world example of designing an IoT system consisting of three interconnected boards:

1. Main Control Board: Responsible for overall system control, data processing, and communication with the cloud.
2. Sensor Board: Integrates various sensors (e.g., temperature, humidity, pressure) and transmits data to the Main Control Board.
3. Power Management Board: Provides regulated power to the entire system and includes battery management functionality.

Using Multi-Board Project, the design process would involve the following steps:

1. Create a new Multi-Board Project and add the three boards (Main Control, Sensor, and Power Management).
2. Define the inter-board connections, such as power supply lines, data communication interfaces (e.g., I2C, SPI), and control signals.
3. Design the schematic and PCB layout for each board, focusing on their specific functionalities and requirements.
4. Synchronize design data across all boards to ensure consistency and proper connectivity.
5. Verify the system integration using 3D visualization tools, checking for mechanical fitment and clearance issues.
6. Generate manufacturing outputs for each board and proceed with prototyping and testing.

By utilizing Multi-Board Project in Altium, designers can efficiently manage the complexity of multi-board systems, streamline the design process, and ensure a more reliable and cost-effective final product.
