High-speed interface design and analysis complexity is only going to increase as edge rates and data rates get faster and voltage rails decrease. Engineering managers should recognize that setting up a highspeed interface analysis process requires an investment in simulation libraries, analysis products, and people.

When you invest in tools, do your homework first. Check to see if prospective tools can really address some of the tough issues presented in this article and that they provide you the growth path you need for the future. Perform thorough (and possibly lengthy) comparative evaluations of potential products to see if they address your current signal integrity, timing, power delivery, and crosstalk analysis needs, but also keep an eye to the future&#151it will arrive sooner than you think.
