Accelerating the Design Cycle : Moving from Discipline-Centric to Product-Centric Design


Reading time ( words)

Defining the characteristics of a new product, such as features, size, weight, and battery life, is the job of marketing. Realizing those design requirements is the responsibility of a multidisciplinary team consisting of product architects, hardware engineers, software engineers, mechanical engineers, packaging engineering, manufacturing engineers, purchasers, etc. 

Today, the design process in most cases fans out from the requirements as defined by marketing into multiple independent design threads that converge at the prototype. There is usually no systematic method for these different disciplines to communicate their work to the other disciplines. This lack of communication often leads to conflicting design decisions, such as when an electrical engineer or purchaser selects a component without having any way of knowing that it interferes with the enclosure. Extra design turns are often needed to resolve these conflicts at the prototype stage.

This obstacle, and many others, can be overcome by a product-centric design process that enables all disciplines to work collaboratively during a new virtual prototyping and detailed design. During the architectural validation or virtual prototyping phase, each contributor can optimize the design from their own perspective with visibility and change notices from the others. The product optimization completed during the virtual prototyping process seamlessly transitions to detailed design, preserving all the critical decisions without data loss or re-entry. Product-centric design ensures that the evolving design meets the requirements of every discipline, reducing late stage design changes and enabling the product to be optimized to a higher degree than is possible with current methods.

Limitations of the Discipline-Centric Process

Looking back just a few years, developers of electronic products primarily competed based on the functionality of their design as determined by unique hardware and software features. Today, with much of the key functionality of electronic products having been commoditized in system-on-chips (SoCs) or application processors, electronics companies are now competing across a wide range of fronts: size, weight, style, battery life and features. The result is a greater need than ever for collaboration across the multiple disciplines that are responsible for providing this much broader range of attributes. More than ever before, a multidiscipline collaborative effort is required to deliver the best design that conforms to marketing requirements in the shortest possible time and at the lowest possible cost.

Yet the tools used to support product development and the process itself have not yet evolved to this new reality. In most cases, the marketing department draws up the requirements documents that then explode into multiple independent paths. The creative team styles the product. The procurement team looks at part cost. PCB designers design the boards one at a time. The manufacturing team decides where to make the product and what processes to use. Mechanical engineers design the enclosure. There may be some limited informal collaboration between disciplines using a spreadsheet or flowcharting tool prior to detailed design, but for the most part, each of these disciplines works independently with relatively little interaction with the others. This is a critical time where architectural decisions are being made with very little validation. In addition, this is generally a sidebar process whose results are not easy to integrate back into the separate design disciplines or into the detailed design; any communications errors can be disastrous.

EMA President Manny Marcano: EDA Tools Are Essential

04/03/2020 | Andy Shaughnessy, I-Connect007
In this interview, Editor Andy Shaughnessy speaks with Manny Marcano, president of EMA EDA Automation, who shares an update on the company's current level of business operations under COVID-19 restrictions. Marcano explains that EMA is classified as an essential business due to its work with the defense segment and that employees are now working from home. He also discusses the company's free work-from-home license offer and why he is available to help any designers or design engineers who have questions during these changing times.

This Month in Design007 Magazine: Mentor—Managing Small Problems for Profitability

03/26/2020 | Andy Shaughnessy, I-Connect007
At DesignCon, I met up with Todd Westerhoff, product marketing manager for highspeed design at Mentor, a Siemens Business, to discuss common design profitability issues and cost-aware PCB design. He explains how simple problems can “slip through the cracks” and cause delays, what you can do, and how first-order analysis can make simulation accessible to designers who wouldn’t simulate otherwise.
