New SI Techniques for Large System Performance Tuning
Large systems with multiple configuration options and extended product lifecycles provide performance tuning opportunities such as SerDes setting optimizations and manufacturing improvements. This paper describes newly-developed techniques for equalization tuning and discontinuity reduction, offering additional design margin. Cost reductions are also achieved as new Signal Integrity (SI) techniques demonstrate performance parity removing non-essential re-timers and PCBs layers. This is the fourth in a series of DesignCon papers detailing the design and implementation of a system characterized by multiple thousands of interconnected serial links spanning dozens PCBs, operating at 3rd and 4th generation serial link data rates (6 to 12 Gbps).
