Firms are experiencing increased pressure as design schedules get shorter and delivery deadlines get tighter.

Product complexity is increasing, too, as customers demand differentiated, feature-rich products. Often, design errors and problems are found late in the design process or even after release, necessitating costly engineering change orders (ECOs).

Best-in-Class firms feel these pressures acutely. They are 24% more likely to differentiate their products via performance and capabilities and twice as likely to differentiate based on faster time-to-market.

In the face of an engineering environment filled with both external business pressures and internal development challenges, there must be a better way of doing things.

Enter “Correct by Construction” Methodology

Correct by Construction methodology is the practice of introducing massive improvement into the printed circuit board (PCB) design process by moving manufacturing and performance validation via design rule / design for manufacturability (DFM) checks and simulation into the PCB design system and integrating it with other design activities

Think of Correct by Construction as moving manufacturability and performance analysis (DFM checks, integrated constraint management, design rule checks, electrical checks, simulation, etc.) from a post-process step run at the end of the design or by the manufacturer into an integrated solution within the PCB design system. Correct by Construction is a major advance in the design of PCBs, allowing users to ultimately eliminate many of the iterations used for manufacturability and performance analysis today, thus making the overall flow more efficient.

Instead of waiting until a PCB design is completed to perform manufacturing and performance validation, Correct by Construction integrates this as an “in-line” part of the PCB design process. The result of in-line manufacturing and performance validation is improved new product development and introduction (NPDI) — better cycle time / faster time-to-market, reduced costs, and improved product quality.

By identifying and correcting issues during development, the cost to fix design flaws is low. This improvement results from integrating many design check / DFM check activities into early design, yielding real-time feedback that is critical to avoid costly redesign-rework that occurs late in the product development cycle.

As Best-in-Class PCB developers integrate a real-time Correct by Construction methodology into PCB design, they are reaping major benefits by producing a design that is right the first time (i.e., “correct by construction”) and by avoiding costly ECOs issued after the product has gone into manufacturing.

Strong Organizational Maturity for the Best-in-Class

The Best-in-Class are moving many manufacturing and performance validation activities into the design stage to reap the full benefits of a Correct by Construction design methodology (Figure 1).

The value of Correct by Construction methodology comes not from moving one of these activities earlier in the design cycle, but from moving all activities and being able to do them in real time. To maximize the benefits of Correct by Construction, leaders are adopting a holistic approach to bring manufacturability and performance analysis (DFM checks, integrated constraint management, design rule checks, electrical checks, simulation, etc.) into the design phase to achieve Best-in-Class results.

Next Steps

Correct by Construction methodology elevates in-design analysis for PCB to a new level to deliver shorter cycle times, lower costs, and higher quality. As Best-in-Class PCB developers integrate real-time, Correct by Construction methodology into PCB design, they are reaping massive optimization benefits by reducing cycle time and costs, and improving product quality while achieving real-time product feedback.

Technology must have operational meaning, purpose, and application for you to make an investment. Correct by Construction methodology meets these criteria, producing a better PCB development system that ensures you stay one step (or more) ahead of the competition. Driven by pressures and challenges, Industry-Leading designers are adopting Correct by Construction methodology to perform manufacturability and performance analysis in-line to avoid costly rework and ECOs later. In short, the benefits of Correct by Construction methodology are real.
