Automated network design, optimization and verification enabled by accurate timing analysis with Capital Network Designer

By Sarah Bartash

As we announced in our blog here, our new Capital website experience brings you the most up-to-date Capital software information and support. We are pleased to feature Capital Network Designer here in our Product Spotlight, highlighting some of the information and resources found on our new site.

Networks are a critical aspect of all modern vehicles. By using Siemens Capital software to help design ‘right-sized’ communications networks with detailed timing analysis, optimize and verify network designs to ensure quality and accelerate development, you can deliver accurate communication network implementation.

Network design is interwoven with the design of the electrical and electronics (E/E) architecture, software and the electrical systems. Network design is not an isolated activity but rather a contributor in a collaborative, multi-domain workflow that spans requirements definition, architecture-, software-, electrical- and network design. Original equipment manufacturers (OEMs) are looking for model-based systems engineering (MBSE) solutions that are well-integrated and allow data to flow naturally between domains. When the domains are disconnected or poorly connected, there is an increased cost of ownership as migration of data is expensive.

Accelerate design of networks with guaranteed delivery

The E/E systems development flow has network design as an integral element. Siemens Digital Industries Software brings network-, architecture-, software- and electrical-system design under one holistic ecosystem with the necessary integrations.

Capital™ Network Designer software is a model-based network design and validation tool ensuring quality and accelerated network implementation. It helps OEMs design validated and correct networks that improve brand value by providing the essential tooling for designing, optimizing and verifying the networks and creating the electronic control unit (ECU) definitions that are sent from OEMs to Tier 1 suppliers.

Capital Network Designer provides support for Ethernet, service-oriented architecture (SOA), scalable service-oriented middleware over IP (SOME/IP) and service discovery, all underpinned by timing
analysis and validation.
