VHDL Reference Guide

Preface

About This Manual

This manual describes how to use the Xilinx Foundation Express program to compile VHDL designs.

Before using this manual, you should be familiar with the operations that are common to all Xilinx software tools: how to bring up the system, select an appropriate tool, specify operations, and manage design data. These topics are covered in the Quick Start Guide.

You must consult The Programmable Logic Data Book for device-specific information on Xilinx device characteristics, including readback, boundary scan, configuration, length count, and debugging. The Programmable Logic Data Book is available in hard copy and on the Xilinx web site (http://www.xilinx.com). See http://www.xilinx.com/partinfo/databook.htm for the current version of this book.

For specific design issues or problems, use the Answers Search function on the Web (http://www.xilinx.com/support/searchtd.htm) to access the following.

If you cannot access the Web, you can install and access the Answers book with the DynaText online browser in the same manner as the Xilinx book collection. The Answers book includes information in the Answers Database at the time of this release.
