Take a look at the electronic design automation software and computer-aided design software landscape, and you’ll find plenty of options for PCB design software. Altium Designer and Mentor PADS are two popular platforms for professional PCB designers. These two platforms have a number of features in common, but the proactive design engineer should take time to compare how each platform will help ensure productivity.

ALTIUM DESIGNER

A unified PCB design package that integrates advanced PCB design and layout features with data management and ECAD/MCAD collaboration features in a single program.

Your PCB design software is a key determinant of your design productivity, and your team needs access to a complete set of features for taking a new circuit board from idea to finished product. If you’re on the fence between Mentor PADS and Altium Designer, you’ll find that these two high-level PCB design software platforms are ideal for the professional design engineer. However, Altium Designer contains some features that make it unique compared to Mentor PADS.

Feature Comparison: Altium vs Mentor

Altium Designer and Mentor PADS both contain many of the standard features any PCB designer would expect to find in their PCB design software. These features include basic board design, component layout, and trace routing tools that are required to build any new circuit board. These features include:

What is Missing from Mentor PADS?

Altium Designer distinguishes itself from Mentor PADS and many other PCB design software programs in that it integrates many more design features into a single program. Altium Designer also has specialized interactive and auto-interactive routing tools that aid layout tasks for more complex board designs. The integrated features in Altium Designer also include an IPC-compliant component creation wizard that instantly generates schematic symbols and PCB footprints for proprietary components.

The data management and production planning tools provide design teams with many important benefits. These tools integrate with the other design features in Altium Designer, whereas Mentor PADS leaves you to adapt a set of third party software platforms into your workflow. There are other standard design features that are completely absent from Mentor PADS, such as multi-board design, full mechanical design integration, and important collaboration features.

  • Rules-driven design: The underlying design rules engine in Altium Designer ensures your PCB design rules and constraints are followed throughout the schematic design and PCB layout process. These constraints can be edited and examined at any time during the layout process, including during interactive routing.

  • Multi-board design: Many products outside the consumer electronics space require more than one board for a variety of reasons. Altium Designer includes features for hierarchical schematic design and PCB layout creation on multiple boards.

  • Stackup materials library: Advanced electronics may require an alternative substrate to FR4. With the stackup materials library in Altium Designer, you won’t need to manually define material properties for alternative stackup materials. These material properties are included in the simulation tools in Altium Designer.

  • Interactive and auto-interactive routing tools: Routing components with large pin counts can be extremely time-consuming, but Altium Designer’s auto-interactive routing tools help designers remain productive. These tools help you quickly route traces in batches while also checking your design rules as you work, ensuring your board will be functional and manufacturable.

  • Real-time BOM and supply chain management: When editing or reusing existing designs and preparing for a new manufacturing run, your design tools need to provide immediate sourcing and component data updates. Altium Designer’s component management features allow you to instantly swap components in the event components become obsolete or unavailable.

  • ECAD/MCAD collaboration in advanced mechanical design software: Complex products require mechanical packaging design alongside electrical design. Altium Concord Pro provides the most advanced ECAD/MCAD collaboration toolset within Altium Designer. Altium Designer already includes advanced native 3D design capabilities, and Altium Concord Pro now allows component management and import tools to integrate into popular mechanical design platforms like SolidWorks.

Altium Designer Takes Electronic Design Automation to the Next Level

Mentor PADS and Altium Designer are both excellent PCB design packages, but Altium Designer is a clear winner when it comes to ease of use, design productivity, and breadth of data management features. Altium Designer provides all the standard and advanced design features you need to build cutting-edge technology in a single program, ensuring you remain productive. Compared to Mentor, Altium Designer provides the easiest platform to learn and use.

Features and Benefits of Altium Designer

Altium Designer provides the industry-standard printed circuit board design features you expect to find in any electronic design automation software program and much more. The schematic design, schematic capture, layout design, and simulation features integrate into a single software platform, which allows you to design with peak productivity. The components management and production planning tools in Altium Designer are ideal for team collaboration and data sharing, helping you smoothly transition to a production. The best part of these features is that they are all accessible within a single program, rather than being separated into different programs.

Altium Designer also gives design teams access to a number of addons that are ideal for specialized applications. The TASKING, xSignals, PDNA, and IPC Footprint tools also integrate into Altium Designer. Contrast this with Mentor PADS, which still separates many features into different software applications. All the features in Altium Designer are built on top of a rules-driven design engine, allowing your design rules and constraints to be accessed by any of the features in Altium Designer.

The new materials library in Altium Designer allows you to easily select from a large number of common materials for use as your core, prepreg, and laminates. You can also design your ground plane and signal layers as part of your stackup. Once you’ve finished your layout, you can then take your design data and immediately import it into your simulation and production planning tools. You’ll be able to move through the entire PCB design process with Altium Designer.

With the ultra-accurate computer-aided design and production planning tools in Altium Designer, choosing between Altium Designer and Mentor PADS should be a no-brainer. With the new features in Altium Designer and its easy-to-use interface, you’ll now have access to extreme ECAD/MCAD collaboration tools, data management features, and standard PCB design tools in a single program. No other PCB design software package offers the same level of flexibility and ease of use as Altium Designer.

Altium also gives you the resources you need to design successfully for any application. You’ll have access to the AltiumLive forum, podcasts and webinars with industry experts, an extensive knowledge base, and technical white papers with plenty of design tips, and design tutorials. No other PCB design software company is this invested in your success.

Altium Designer has set a new standard in PCB design integration and analysis. By integrating your layout, schematic design, data management, and simulation features into a single platform, you can easily pass design data between these important design features and take control over all aspects of your next product.
