Frequently asked questions

What is electrical design software?

Electrical design software are specialized tools engineers and designers use to meet the challenges of today's most complex products. These challenges include connectivity, safety and cost control. It ensures the signals from electronic units, such as those with embedded software or electro-mechanical devices, such as a switch or a motor, are connected correctly. It is used to confirm a safe and robust supply of power to all components in a system and also optimize the electrical distribution system for weight, cost and mechanical packaging. With this specialized software, you can ensure that the design complies with regulations.

These challenges are growing, driven by the fact that innovative product functionality is now primarily delivered by electrical, electronic and software systems. Software specifically created for E/E development helps you design, manufacture, document and maintain in a time of rising complexity. 

What are the benefits of using electrical design software?

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 made more manageable with the Capital electrical portfolio

The benefits include digitalization and automation within the physical flow or electrical distribution system (EDS). This streamlines the distribution of power and signals, helps make wiring harnesses more efficient and provides confidence that the documentation and diagnostics will be accurate. 

What sets Siemens' electrical design software apart from the competition?

As part of the Siemens Xcelerator portfolio of software, services and application development platforms, Capital is integrated with adjacent Siemens solutions. This includes the Teamcenter portfolio for product lifecycle management, NX software for mechanical design and Mendix low-code development environments. This combination creates one of the most comprehensive wiring harness development solutions for efficiently engineering and manufacturing today’s smart products. 

Capital contributes to an optimized digital twin comprising a validated harness model and a digitalized manufacturing process model. This can transform your company's engineering, costing and manufacturing performance, ultimately boosting profits. With Capital, teams can choose from four electrical connectivity flows, each providing generative design principles and a path to a fully automated solution. Enable your teams with a semi-automated interactive design flow and progress toward a more fully automated model.
