Siemens Announces Capital with Enhanced E/E System Development Capabilities
Enhancing solution connectivity within the accelerator portfolio
Capital is offering several options for small and medium-sized business customers.


Today, electrical and electronic (E/E) systems are becoming increasingly complex. Consequently, robust verification and traceability are required, and reliance on software is growing.

On June 18, Siemens Digital Industries Software announced 'Capital,' software that enhances E/E system development capabilities.

With this enhancement, Capital has added E/E system software architecture, network, and embedded software development capabilities, in addition to functions for the design, manufacturing, and service of E/E systems. It has been improved to enable integrated management of the product development process, which was previously separated by process, component, and technology.

◇ Can be integrated with other solutions within the accelerator portfolio

Capital is part of Siemens' 'Xcelerator' portfolio, a software, service, and application development platform, and enables integration with Siemens' Model-Based Systems Engineering (MBSE), MCAD, PLM, simulation, and manufacturing solutions.

This allows digital twins to be applied to the product development process, enabling shift-left and verification to be performed early in product development. It is possible to increase development speed and quality and shorten the time to market.

Capital, capable of providing end-to-end integrated support from design to manufacturing and service areas, can now also perform requirements management, multi-domain functional modeling, software simulation, application lifecycle management, and manufacturing plant simulation.

In particular, Capital's model-based approach enables a high level of automation and data continuity through a Digital Thread that links product optimization, implementation, and certification.

Martin O'Brien, Senior Vice President of Siemens’ Integrated Electric Systems business unit, described Capital as “an integrated solution portfolio covering the domains required for E/E system development,” explaining that it “includes specific tools for E/E architecture development and system definition, electrical systems and harnesses, communication networks, and embedded software architecture and execution.”

When asked if it is possible to use Capital to verify compliance with industry standards such as ISO 26262 during the development of products, such as electronic components, Vice President O'Brien replied, “Capital can track requirements derived from system definitions through electrical flow and provides various simulation and verification functions related to regulatory compliance,” adding, “a function that ensures wire bundle separability, a common requirement in the aerospace field.o; was given as an example.

In addition, it was stated, “The Capital VSTAR embedded software stack has been confirmed to cover AUTOSAR standards while satisfying cybersecurity and functional safety requirements, and to support ISO 26262 ASIL D use cases.”

◇ Capital in the Korean Market and Future Goals

When asked for specific examples of how capital was used to improve productivity in Korea, Vice President O'Brien said, "The defense contractor Korea Aerospace Industries (KAI) is a prime example," adding, "By utilizing capital in the development of E/E systems, they reduced the wiring system design time by 20% compared to before."

KAI stated through Siemens, “Capital is easy to use, offers excellent automation capabilities, and guarantees a high level of data accuracy,” adding, “We were able to reduce the time required to develop the complex interconnect wiring used in the latest helicopters.”

Capital is a suitable solution for small and medium-sized enterprises as well. "A significant number of Capital's new customers are small and medium-sized enterprises," said Vice President O'Brien. "Siemens is offering several options to enable SMEs to purchase its solutions at an affordable price."

Examples include modular licensing and short-term tool rentals. Siemens also stated that it operates a large-scale academic program that provides tools, including capital, to educational institutions such as universities at nominal prices.

Vice President O'Brien emphasized that they will continue to “spend no effort in active investment, such as projecting generative design technology into Capital,” and “further strengthen the integration of solutions within the Siemens accelerator portfolio, such as Capital, NX, Teamcenter, and Simcenter.”
