From Silos to Synergy: How AI Is Improving ECAD and MCAD Collaboration

That complexity is changing the way engineering teams collaborate.

In the past, electrical and mechanical design teams often worked in separate environments using different tools, processes, and vocabularies. But waiting until late in development to check whether electronic and mechanical systems fit together is no longer practical. Companies need to move faster, reduce design iterations, and bring reliable products to market with greater confidence.

That is why strong ECAD and MCAD collaboration is now essential — and artificial intelligence is making that collaboration even more powerful.

Why ECAD and MCAD Collaboration Matters

Electronic and mechanical systems are more connected than ever. Product teams need to consider circuit board layout, enclosures, component placement, thermal behavior, manufacturability, signal integrity, weight, packaging, and mechanical constraints at the same time.

If electrical and mechanical teams work in silos, problems may not appear until late in the process.

Common issues include:

• Components interfering with mechanical housings
• PCB changes not reflected in the mechanical design
• Mechanical constraints not communicated to electronics teams
• Incorrect versions used during simulation
• Late-stage rework and design respins
• Delays caused by manual data exchange
• Misalignment between BOMs and design intent

In competitive markets, those delays can be costly. Product compatibility must be designed in from the beginning, not checked only after fabrication.

The Challenge of Interdomain Collaboration

ECAD and MCAD collaboration has traditionally been difficult because the disciplines rely on different design environments, workflows, and terminology.

Many teams have tried to manage collaboration through email, file transfers, screenshots, spreadsheets, or internal processes. While these methods may work for simple communication, they often fall short when managing complex product development.

The result is a disconnected workflow where design intent can be lost, changes are difficult to track, and engineering teams spend too much time reconciling data.

To solve this, the industry introduced the Interdomain Design Exchange, or IDX, format. IDX enables incremental data exchange between ECAD and MCAD tools, allowing teams to share only what has changed instead of transferring complete design files every time.

This helps preserve design intent and improves collaboration across mechanical and electrical domains.

Siemens Brings ECAD and MCAD Together

Siemens builds on IDX with tight integration between NX for mechanical design and Xpedition for electronic systems design.

Together, NX and Xpedition create a more connected environment where ECAD and MCAD teams can collaborate without leaving their native design tools. This supports synchronous and asynchronous collaboration, allowing teams to work in ways that match their processes.

Siemens’ approach helps teams:

• Exchange design changes more efficiently
• Preserve design intent across domains
• Improve communication between electrical and mechanical teams
• Reduce manual rework
• Track changes more clearly
• Improve product-level visibility
• Accelerate design cycles

Because Siemens owns both NX and Xpedition, the integration can go beyond basic IDX compliance and deliver advanced cross-domain functionality.

A Shared Parts Library for Better Co-Design

A key part of successful ECAD and MCAD collaboration is having a shared understanding of components.

Siemens supports this with a shared parts library that includes unified representations of footprints, symbols, attributes, and 2D and 3D component data. This makes it easier to align electronic and mechanical design information and create a more complete product-level bill of materials.

For high-density electronic products, this is especially important.

NX and Xpedition users can leverage synchronized component libraries to support advanced co-design needs such as:

• Components in cavities
• Blind and buried vias
• Copper and solder masks
• Stack-up zones
• High-density interconnect designs
• 3D mechanical clearance checks
• Product-level BOM coordination

This creates a stronger foundation for designing complex electromechanical products correctly from the start.

AI-Enhanced Collaboration Across ECAD and MCAD

Siemens is taking ECAD and MCAD collaboration further by adding AI-enhanced capabilities across the design environment.

AI can help engineering teams make better decisions, reduce repetitive tasks, improve design exploration, and coordinate more effectively across domains.

Examples of AI-enhanced capabilities include:

• Process prediction
• In-tool product chat assistance
• AI-powered digital twins
• Support database search
• Design data digital threads
• Predictive command assistance
• Natural language search
• Optimization recommendations

These tools are designed to help engineers spend less time on repetitive or manual work and more time solving complex design challenges.

Process Prediction for Faster Decisions

AI-driven process prediction can provide real-time insights and recommendations inside ECAD and MCAD environments.

This helps teams identify issues earlier, coordinate next steps, and adjust workflows before problems affect the project timeline. Instead of waiting for design reviews or late-stage validation, engineers can receive guidance while they work.

This supports a more proactive design process where potential conflicts can be addressed earlier.

In-Tool Product Chat Assistance

Siemens is also using large language models to provide in-tool product assistance.

With a natural language chat assistant, users can ask questions in everyday language and receive conversational responses related to Siemens tools and workflows. This can help engineers find commands, understand processes, locate information, and work more efficiently without leaving the design environment.

For newer users, this can reduce the learning curve. For experienced users, it can help speed up access to information.

AI-Powered Digital Twin

An AI-powered digital twin allows engineers to simulate and evaluate electromechanical systems before physical builds.

By combining design data, simulation, and optimization tools, teams can validate performance, explore trade-offs, and identify potential issues earlier. For example, tools such as Simcenter and HEEDS can support design space exploration and signal integrity simulation, helping teams evaluate performance more quickly.

This allows engineers to make informed decisions while the design is still flexible.

Siemens Digital Threads Create Better Traceability

A digital thread connects data across the product lifecycle and across engineering domains. For ECAD and MCAD collaboration, the design data digital thread helps synchronize design information, improve transparency, and create traceability between electronic and mechanical decisions.

This helps teams maintain a single source of truth across tools such as NX, Xpedition, Teamcenter, Simcenter, and HyperLynx.

A strong digital thread can help reduce design respins, improve collaboration, and ensure that the right versions of electronic and mechanical designs are used throughout development.

GenAI in NX: Analyze, Optimize, Generate

Siemens is using generative AI in NX to reduce repetitive work and help designers explore more possibilities.

The Siemens AI philosophy centers on three pillars:

• Analyze
• Optimize
• Generate

With AI-enabled analysis, NX can evaluate design data and provide recommendations based on task context and user behavior. This supports a more personalized workspace and can guide users through complex workflows.

With optimization, AI can help designers explore more design options, evaluate trade-offs, and improve product performance based on constraints and historical data.

With generative capabilities, AI can help create relevant engineering content such as standard parts, material suggestions, or design areas that need attention.

Practical AI Enhancements in NX

Siemens has already introduced AI-driven functionality that improves everyday design workflows.

One example is the select similar edges command in NX. This feature helps users automatically identify and select edges similar to a chosen edge, reducing repetitive manual selection on complex parts.

This can be especially useful for tasks like applying blends or working with repetitive features.

Benefits include:

• Faster selection on complex parts
• Reduced risk of missing edges
• Improved workflow efficiency
• Reuse of common edge profiles
• Better support for assemblies and part design

NX also includes personalized command search capabilities that adapt to user behavior. By learning frequently used commands and workflows, NX can provide more relevant search results and help users work more efficiently.

AI in Xpedition for Electronic Systems Design

AI is also improving electronic systems design in Xpedition.

Siemens has built AI capabilities into its electronic design automation portfolio to increase productivity, optimize designs, and improve decision-making.

Examples include:

• AI-driven design space exploration with HyperLynx
• Faster signal integrity analysis
• Surrogate models to accelerate future analysis
• Supply chain prediction using Supplyframe
• Component cost and availability insights
• Natural language querying of datasheets
• Chatbot-style assistance for component selection

These capabilities help electronics teams make smarter decisions earlier, especially when balancing performance, availability, cost, and sourcing risk.

Customer Example: Unison

Unison, a GE Aerospace company, provides controls and engine performance monitoring solutions for aerospace, defense, and space applications. In these industries, design requirements are strict, and components are critical to safe operation.

By using Siemens Xpedition and NX together, Unison improved collaboration between ECAD and MCAD teams. The integration helped create a digital thread between the two environments and provided a single source of truth for baselines, proposals, and responses.

According to the e-book, work that previously took many weeks was completed in just days.

The Role of the Comprehensive Digital Twin

A comprehensive digital twin is more than a model of a product. It connects data across design, simulation, manufacturing, operations, and the supply chain.

For ECAD and MCAD teams, a comprehensive digital twin helps simulate how complex electromechanical systems and processes operate. It can also support lifecycle analytics, operational monitoring, and manufacturing planning.

As part of Siemens Xcelerator, the comprehensive digital twin connects tools such as NX, Xpedition, Teamcenter, Simcenter, HyperLynx, and other Siemens solutions to support better collaboration and decision-making.

Embrace Complexity with AI-Enhanced Engineering

Product complexity is not slowing down. Electronics and mechanical design will only become more interconnected as products become smarter, smaller, more connected, and more software-driven.

To compete, engineering teams need tools that help them collaborate across domains, manage complexity, and move faster without sacrificing quality.

Siemens’ AI-enhanced ECAD and MCAD environment helps teams:

• Improve collaboration across domains
• Reduce design respins
• Preserve design intent
• Work from synchronized design data
