DECEMBER 2021 I DESIGN007 MAGAZINE 39 development time by 29%— six times the rate of improvement by all others. Best-in-class organizations also met their time-to-market targets 76% of the time, a 17% higher rate than all others. • It reduced product costs; 71% of best-in-class designers met their product cost targets. • Higher product quality was achieved; 77% of best-in-class firms met their product quality targets. Plus, best-in-class products were more likely to work right the first time and less likely to require rework: the best-in- class teams improved their ECOs, aer release to manufacturing, by 21%. While I've pointed out plenty of obstacles to complete digital verification with an optimal digital twin, there are still many steps an engi- neering team can take today to leverage exist- ing technology and minimize physical proto- types. Organizations are incorporating dis- crete simulators and checkers (e.g., for SI, PI, thermal, vibration, or manufacturability) and are reporting first-pass success. Incorpora- tion earlier in the design process has improved engineering decision-making and minimized iterations with specialists. Fundamentally, leveraging a digital twin enables easier, faster verification which ensures higher quality products without time- and cost-consuming respins.

Lest I cause anyone to fear for their jobs, I should note that electronics systems represent a far more complex, multi- domain, multi-discipline problem than purely mechanical structures. An Aberdeen survey asked about processes for design verification. It classified the use of simulation by design engineers early in the design process as best-in-class for the following reasons: • First, it enabled product innovation and optimization, because physical prototypes were reduced 27% using virtual prototypes and virtual testing. is allowed them to explore hundreds of design iterations, freeing them up to identify and focus on designs with the highest potential. • It improved time to market. Best-in-class designers improved their length of Figure 2: An optimal design process leverages digital verification to minimize respins.
