Capital X
Cloud-native E/E systems engineering
Move electrical, electronic and software systems design and validation to the cloud for multi-domain mechatronics-software collaboration.

Capital X is Siemens' cloud-based electrical/electronic (E/E) systems engineering software, covering electrical architecture, network communication and embedded software design, engineering and validation. It manages complex harness, power distribution and software architecture in one unified data model, collaborating in real time with mechanical and electronic design.
Key capabilities
Electrical architecture
Vehicle/machine electrical architecture and power distribution design.
Harness & routing
Harness engineering, wiring diagrams and manufacturing data.
Network communication
CAN/LIN/Ethernet in-vehicle network architecture and simulation.
Embedded software
Manage mechatronics-software complexity alongside the software architecture.
What it delivers
- Unified mechatronics-software data reduces cross-domain rework
- Design-time validation shortens E/E development cycles
- Cloud collaboration keeps distributed teams in sync
- Real-time linkage with mechanical design avoids interference and omissions
