Xpedition: Mentor’s Flagship PCB Design Platform

Overview of Xpedition

Xpedition is Mentor’s high-end PCB design solution, targeting complex designs in industries such as telecommunications, automotive, aerospace, and defense. It offers a comprehensive set of tools for schematic capture, layout, routing, simulation, and manufacturing preparation.

Schematic Design with Xpedition

Xpedition’s schematic editor allows engineers to quickly capture their circuit designs using a intuitive interface. Key capabilities include:

• Hierarchical design support
• Multi-sheet schematics
• Electrical rule checking (ERC)
• Integration with simulation tools

Constraint-driven Layout in Xpedition

One of Xpedition’s standout features is its constraint-driven layout environment. Engineers can define a wide range of design rules and constraints, such as:

• Spacing and clearance rules
• Differential pair routing rules
• High-speed design constraints
• Manufacturing constraints

Xpedition’s layout engine then auto-routes the design while adhering to these constraints, ensuring the PCB will meet all requirements. This greatly reduces manual effort and potential for errors.

3D PCB Visualization with Xpedition

Xpedition includes robust 3D visualization capabilities that allow engineers to view their PCB design in a realistic 3D environment. Benefits of 3D visualization include:

• Detecting potential mechanical interferences
• Validating component placement
• Communicating design intent to stakeholders
• Generating 3D models for mechanical CAD tools

PADS: Mentor’s Desktop PCB Design Solution

Overview of PADS

PADS is Mentor’s desktop PCB design platform, aimed at individual engineers and small teams working on less complex designs. While more affordable and accessible than Xpedition, PADS still offers a powerful set of schematic capture, layout, and analysis tools.

Schematic Design in PADS

PADS includes an intuitive schematic editor that supports hierarchical designs and multi-sheet schematics. It also offers integration with popular simulation tools for seamless design verification.

Layout and Routing with PADS

PADS provides a streamlined layout environment with advanced auto-routing capabilities. Engineers can define design rules and constraints, and the auto-router will generate an efficient, manufacturable PCB layout. PADS also supports interactive routing for fine-tuning critical routes.

Analysis Tools in PADS

PADS includes a variety of analysis tools to help optimize PCB performance, including:

• Signal integrity analysis
• Thermal analysis
• EMI/EMC analysis
• Design for manufacturability (DFM) checks

These tools allow engineers to identify and resolve issues early in the design process, reducing the risk of costly redesigns.

Comparing Mentor PCB to Competitors

Mentor vs. Altium

Altium Designer is another popular PCB design platform. While both offer robust feature sets, key differences include:

Feature	Mentor	Altium
Scalability	Better suited for larger, more complex designs	More focused on individual designers and smaller teams
Simulation	Offers more advanced simulation capabilities	Simulation feature set not as extensive
Price	Generally higher cost	More affordable for small businesses and startups

Mentor vs. Cadence

Cadence offers the Allegro PCB design platform, which competes with Mentor’s offerings. Comparisons include:

Feature	Mentor	Cadence
Constraint management	Robust constraint management features	Constraint management not as comprehensive
Usability	Steeper learning curve, but more powerful	More intuitive interface, easier to learn
3D capabilities	Extensive 3D visualization and CAD integration	3D features not as advanced

Ultimately, the choice between Mentor, Altium, and Cadence will depend on the specific needs and budget of the design team.
