PCB Technology Leadership Award Winner: SIENNA ECAD

By Jim Martens

I’d like to congratulate the two Technology Leadership Award winners who used the PADS design flow on their boards.

This week we’ll look at SIENNA ECAD Technologies in India who took home a win in the Transportation and Automotive category with a design created by Krishna Murthy BS, Raghava Charyulu V, and Savita R. Ganjigatti.

SIENNA ECAD’s design is a debug board for DUT. The judges particularly noted the extremely dense placement. The design team used PADS Physical Design Reuse to assist them with the placement of 48 identical channels. Constraint management was a huge challenge, including restrictive placement keepouts, large trace clearances for analog signals, and length matching for many high-speed traces, including the serial peripheral interface (SPI) bus. Congratulations Krishna, Raghava, and Savita!

In my next blog, I will highlight the winning design from Murrelektronic in the Industrial Control, Instrumentation, and Medical category.
