One method to achieve higher data rates is to encode multiple bits per transition; PAM-4 does this by sending 2 bits every unit interval. The result is multiple eyes at the receiver, as opposed to just a single eye.
This video demonstrates how HyperLynx includes PAM-4 signaling in serial link analysis to allow for analysis of links that use this signaling standard.

I was just thinking about the party game Hot Potato. It reminded me of today’s increasingly competitive marketplace: Accurate thermal analysis must be performed, and any potential issues have to be identified and addressed as early as possible in the design cycle. Otherwise the system will run into problems, market windows will be missed, and someone will be left holding the hot potato. Trust me, you do not want to be that someone.

The I-Connect007 team recently interviewed Mike Jouppi, one of the champions of thermal management in PCBs. Mike spent decades working on updating the old IPC current-carrying data, which dated back to the 1950s, and he is the primary architect behind IPC-2152— the standard for determining current-carrying capacity in printed board design. As Mike explained in this wide-ranging interview, even if you’re using the latest thermal design software, you still need to have a firm understanding of the fundamentals.

Editor's note: The following is an excerpt from "The Printed Circuit Designer's Guide to... Signal Integrity by Example," written by Fadi Deek of Mentor, a Siemens Business. Deek explores how to reach effective design solutions and make strong engineering tradeoffs through analysis techniques, best design principles, and software tools to achieve accurate simulations and measurements.
