Capital Harness Design

Basics of electrical engineering principles: Ohm’s Law, Kirchhoff’s Laws, and power calculations; vehicle electrical architecture and power distribution networks; overview of 12V, 24V, and high-voltage systems for EVs and hybrids; common electrical loads — resistive, capacitive, and inductive. Learning outcome: understand foundational automotive electrical principles and analyse different vehicle electrical systems and loads.

Importance of libraries in schematic design; creating and managing reusable component libraries in Capital Logic; defining properties for fuses, relays, connectors, and terminals; library validation and compliance with industry standards. Learning outcome: build and maintain accurate reusable libraries aligned with ISO, SAE, and OEM-specific standards.

Basic schematic creation with Capital Logic; incorporating essential components and defining power and signal flows; utilizing library components and maintaining naming conventions; generating and managing hierarchical designs. Learning outcome: design basic automotive schematics using Capital Logic and use library components effectively.

Multi-level and hierarchical circuit design in Capital Logic; splice points, inline components, and connector pin mapping; cross-reference management and signal tracing; validation of designs using Capital Logic’s error-checking tools. Learning outcome: create and validate detailed multi-level schematics and implement advanced features like splice points and cross-referencing.

Introduction to generative design — automating design creation based on predefined rules; setting up constraints and design rules in Capital; interactive design flow — manually refining and customizing generative designs; iterative validation and optimization of designs. Learning outcome: use generative techniques to accelerate schematic and harness creation while balancing automation with customization.

Translating schematics into harness designs using Capital Integrator; wire routing and bundling based on packaging constraints; integrating splice points, branch-offs, and multi-connector configurations; generating wiring diagrams, manufacturing data, and reports. Learning outcome: develop wiring harness designs that integrate with schematics and optimize routing and bundling for manufacturability.

Performing electrical analyses — voltage drop, current flow, and circuit integrity; identifying design issues and generating corrective feedback; validating compliance with OEM standards and industry regulations. Learning outcome: analyse and optimize designs for performance and compliance, and integrate analysis results to refine designs.

Lighting systems — design for headlamps, DRLs, and LED modules; infotainment systems — audio, display, and connectivity circuits; safety systems — ABS, airbags, and ADAS-related wiring; HVAC systems — fan controls, sensors, and actuators. Learning outcome: design subsystems using Capital Logic and Integrator and address specific subsystem requirements and constraints.

Automating BOM and wiring list generation in Capital; customizing reports for manufacturing, testing, and serviceability; exporting diagrams and data to other tools for collaboration. Learning outcome: generate detailed reports and diagrams efficiently and tailor reports to project-specific requirements.

Designing and validating a comprehensive automotive electrical system; integrating generative and interactive design flows for efficiency; conducting complete analysis and generating all project deliverables (BOM, harness, and schematics); final presentation of project outcomes. Learning outcome: demonstrate expertise in the full Siemens Capital design workflow and deliver a professional-grade, validated design with complete documentation.
