Introduction

This application note provides board-level design guidelines for SmartFusion®2 and IGLOO®2 devices. The Layout Guidelines for SmartFusion2- and IGLOO2-Based Board Design section describes the PCB design. These guidelines must be treated as a supplement to standard board-level design practices.

Good board design practices are required to obtain expected performance from both PCB and SmartFusion2/IGLOO2 devices. High quality and reliable results depend on minimizing noise levels, preserving signal integrity, meeting impedance and power requirements.

This document assumes that the reader has a good understanding of the SmartFusion2/IGLOO2 devices, is experienced in digital and analog board design, and knows about the electrical characteristics of systems.
