Introduction

Good board design practices are required to achieve expected performance from both Printed Circuit Boards (PCBs) and PolarFire® devices. High-quality and reliable results depend on minimizing noise levels, preserving signal integrity, meeting impedance and power requirements, and using appropriate transceiver protocols. These guidelines must be treated as a supplement to the standard board-level design practices.

This document is intended for readers who are familiar with the PolarFire device, experienced in digital board design, and know about the electrical characteristics of the systems. It discusses power supplies, high-speed interfaces, various control interfaces, and the associated peripheral components of the PolarFire FPGAs.
