DECEMBER 2020 I DESIGN007 MAGAZINE 49 Digitally Integrated and Optimized Multi-Domain Design Digitally integrated, optimized multi-domain design establishes a digitally integrated solu- tion across multiple domains to reduce manual intervention, foster collaboration, and improve transparency across disciplines. In creating a digital thread between domains, they establish traceability and interactivity from one domain to the other. This digitally integrated environ- ment enables efficient, secure, concurrent design across all engineering teams, whether individual contributors work at the same site or across the world. A digital thread between design and manu- facturing enables teams to minimize the re- spins that often happen between the design and manufacturing teams. Integration between design and manufacturing is essential for pro- ducing products that are high quality, low cost, and on time. A digitally integrated solution enables teams to optimize the costs associated with a project, accelerate design time, man- age data integrity, and improve the quality of results. Model-Based Systems Engineering (MBSE) A model-based systems engineering approach from product requirements through manufac- turing helps engineering teams solve the mul- titude of complex and challenging tasks pre- sented by full system design. It allows team members to view the entire system and model pieces of that system individually, earlier in the design flow. It does not matter if those pieces are on the electronics side, the electrical side, the mechanical side, or the software side. By looking at the entire system through a model-based systems perspective, teams can not only look at the electrical and functional trade-offs earlier in the design cycle, but also product trade-offs that might be based on such things as weight, cost, or even avail- able components. And by leveraging the tech- niques of MBSE, interfaces can be established very early in the design cycle between each of the individual domains. In doing so, the imple- mentation within each domain can be isolated from the others. This allows engineering teams to work in parallel, and it gives an earlier view of the entire product that the team seeks to develop. Digital Prototype-Driven Verification By integrating verification throughout the multi-board electronics design process—start- ing very early, long before physical proto- types—engineering teams can smooth the entire design process and increase design quality through digital-prototype-driven, shift- left verification and cross-domain modeling. Shifting verification to the left in the design flow using automated, integrated tools reduces product schedules and increases the likelihood of on-time product launches. Cost and time are saved by finding problems early during design, minimizing design iterations, and manufactur- ing respins.
