The ECAD team at Seagate Technology was building a 5U chassis, but due to its multiple interconnected boards and cables, it was a challenge to understand the IR drop and system challenges. Subramian Ramanathan, Sr. Engineering Manager, and Shashi Singh, Hardware Engineer, describe how they used the Cadence® Allegro® schematic and layout technology with the Cadence Sigrity™ PowerDC™ tool for simulation. These tools gave results immediately, allowing modifications to the layout to lower IR drop before sending to review, ultimately accelerating review cycles and lowering overall cost.
