Electrical design software

Accelerate sophisticated electrical design for wire harnesses, manufacturing and service publications with Siemens' robust software. Differentiate your products and drive complex vehicle and aircraft electrification through the efficient development of electrical and electronic (E/E) systems.

Why use electrical design software?

Products are becoming smarter and more complex as they offer enhanced capabilities, interactivity and adaptability to meet user needs. The E/E systems that support such highly complex functions are also growing in complexity, making the design of electrical, electronic and embedded software and network components more difficult.

To stay competitive, you must find ways to manage this exploding complexity and develop robust E/E systems at an accelerated pace, without compromising quality.

According to Lifecycle Insights’ Engineering Executive Strategic Agenda study:


of engineers report the complexity of electrical distribution systems is increasing or increasing greatly.


of engineers report the complexity of electronics is increasing or increasing greatly.


of engineers report the complexity of embedded software is increasing or increasing greatly.

How do you develop more robust and competitive E/E systems to create more efficient, reliable and functional products — faster and cheaper?

Implement an E/E systems development solution. Create a digital thread that enables your electrical, software, mechanical and other key domains to work together, resulting in a more automated and optimized development process.

What can an electrical design solution do for you?

An E/E systems development solution enables you to connect your systems, data and people to design and develop high-quality, robust E/E systems. Create E/E systems faster and more efficiently while incorporating all components: electrical, electronic, embedded software and network communications.

Accelerate with E/E systems solutions

Streamline E/E systems development and get the right design the first time. Ensure traceability of components, requirements, design and changes throughout the development cycle. Verify and validate E/E systems early and continuously.

Frequently asked questions

What are the benefits of using the digital twin in E/E systems development software?

Leveraging the comprehensive digital twin to model your E/E systems allows you to better understand how all components work together throughout the product lifecycle. You can simulate and analyze designs virtually, in real time, and test out changes to the design early in the process. With the digital twin, you can collaborate with multi-domain stakeholders and ensure traceability of all critical information. This in turn helps you develop E/E systems cost-efficiently and faster while reducing risk for your program and business.

What are the benefits of using E/E systems development solution for electrical design?

Designing the electrical systems of increasingly complex products requires powerful tools to ensure all eventualities are considered. Cost, weight, governmental regulation, sustainability and change management are all more manageable with an E/E systems development solution.

The benefits of using an E/E systems development solution for electrical design include digitalization and automation within the physical flow or electrical distribution system (EDS). This streamlines the distribution of power and signals, increases the efficiency of wiring harnesses and ensures accuracy of the documentation and diagnostics.

How does a model-based approach to E/E systems development enhance the development process?

Model-based E/E systems development enables you to leverage models to delve deeper into the specifics of electrical and electronic components. With this approach, you can address detailed aspects such as circuit designs, software functionalities, hardware interactions and E/E system integration within the larger system. Using these model-based principles, you can automate complex systems integration tasks and continuously verify and validate results.

What sets Siemens' E/E systems development solution apart from the competition?

Our E/E systems development solution, Capital, is an integrated solution that is open and interoperable with other key systems such as product lifecycle management, mechanical computer-aided design and application lifecycle management. It enables you to create an unbroken digital thread among domains, connecting your stakeholders, data and processes to control multi-domain information and workflows — ultimately leading to improved quality and accelerated product development.

With Capital, you can leverage the most comprehensive digital twin to model and modify E/E systems development in detail. Uncover optimal E/E systems design in the virtual world before putting your work into real-world physical validation. Capital is personalized and adaptable with a low code embedded environment to enable easy and rapid development of custom applications and integrations.
