About the Technology Leadership Awards

Started in 1988, this program is the longest running competition of its kind in the EDA industry. In fact it is the industry’s only award where design teams using Mentor’s solutions receive recognition by an independent panel of experts for overcoming the most extreme challenges facing PCB design teams today. Just look at the winning designs from previous years to get a sense of the types of technologies and industry segments that are represented in this program. A listing of all of this years winners along with a Technology Leadership Awards webinar are both available for more in-depth information.

Please check back next week for a closer look at the winner in the Industrial Control, Instrumentation & Medical category.
