Digital Thread for Electrical / Electronic Design

The Digital Thread is a foundational element of a successful Digital Engineering implementation.  There is no single thread but many threads. The Digital Threads start with model development and continue through design, manufacturing, field support, and disposal.  The traceability of decisions and outcomes is at the core of the Digital Thread.

Single Source of Truth

In a Digital Engineering process, the product model is the single source of truth and the beginning of the many Digital Threads. The product model must stay connected with the multi-discipline development process through Digital Threads.  A product feature or parameter (e.g., weight, cost) is traceable to the product model.


Decisions and traceability

Decisions and Traceability

The model-based design has verification gates to ensure that the implementation reflects the model definition.  The verification gates are comprised of design reviews, trade-offs, changes and ultimately approval.  The digital conversations behind those activities and approvals become part of the digital thread. If a critical design change is made, a digital record of the concern, options, and decision-makers is available.

Digital Twins

The Digital Twin is an important part of the Digital Engineering design process. It is a multi-discipline model of the product or subsystem for viewing and analysis. Zuken’s CR-8000 for PCB subsystem design allows the user to create a Digital Twin combining multiple disciples ready for analysis. Zuken’s E3.series provides a control panel digital twin and works with MCAD systems for wire harness system modeling.

Verification and the Digital Thread

Recording Verification Events

A foundational element of model-based systems engineering is the verification gate which is comprised of verification requirements.  Each gate represents a confirmation that the implementation is fulfilling the intent of the model and product.  Another benefit of the verification event is maintaining model relevance through the product life cycle.

Data Drives Smart Manufacturing

As the manufacturing floor becomes more automated, the information needed to drive the workflows increases dramatically. Cross-functional teams must collaborate on digital work instructions utilizing mobile and wearable devices to improve quality and reduce waste. The Digital Thread helps convert design data into manufacturing processes and quality data collection.

Features and Benefits

The Digital Thread enables cross-functional teams spanning different organizations to easily and reliably communicate. Today’s complex product development processes demand collaboration throughout the product life cycle including procurement, design, manufacturing and field service.

Digital Engineering processes require the elimination of paper with digital conversations. Utilizing a browser-based tool eliminates the needs of multiple departments to learn a new tool. Engineering, manufacturing, and procurement can review a BOM as a digital conversation.

The Digital Thread can offer huge value in the procurement process. An OEM can source a part to multiple suppliers and have private digital conversations with each. A technical data package is part of the conversation.  The activity may be to acquire part ABC-001.  That activity can have 10 concurrent conversations with 10 suppliers. The purchase history of that part in now part of the permanent design record.

The manufacturing floor has become more connected and so does the organization. The Digital Thread can bring workflows using augmented reality to manufacturing with assembly instructions. Data can be collected from those processes to provide insight into work completed and quality.

Field service is an important factor when considering the Digital Transformation. Technical data needs to be available on mobile devices along with work instructions and in some cases the use of Augmented Reality. Repair records need to become part of the Digital Thread to measure product performance and reliability. Field service records can be the foundation for quality improvement leading to customer satisfaction.

The process is based on a model built upon relationships. The model replaces the document-based design. The model is typically created by the Systems Engineering team who converts system purpose into structure, behavior, and requirements.  The model is considered the single source of truth.

Many companies struggle with design reviews which are typically done through emails and meetings. The approval process may be nothing more than an email. The Digital Thread offers the ability to define a Design Review as an activity comprised of multiple conversations on the BOM, SI, Power, manufacturing, etc.  The activity approver has all this information upon which to base their decision.

The model must remain relevant through the product development process. This is accomplished through verification gates which are comprised of a set of verification requirements. The design can not proceed to the next development phase until the gate requirements are satisfied.  This ensures the product is consistent with the model.

Digital Engineering eBook

This eBook describes an MBSE based process for Electrical and Electronic design. The eBook begins with model content and structure with the purpose of implementation and the need for a “design envelope”.

The biggest challenge in MBSE gaining broad adoption is making the model relevant through the product life cycle. Learn how you can overcome this daunting hurdle while maintaining the model as the single source of truth.
