This white paper reviews how leveraging in-system diagnostics throughout the development cycle can assist engineers in overcoming the challenges design complexity exerts on product development, manufacturing, and overall time-to-market. Readers will gain insight into how they can replace today’s ad-hoc board level validation approaches with an ordered methodology. This enables designers to automatically validate their own hardware designs, optimize system performance, and simplify the process of integrating new hardware with new software. The paper concludes some case studies that will help designers insulate against risks that are derailing product introductions from some of the largest, most respected companies in the electronics business.
