The primary focus of this tutorial is to show the relationship among the design entry tools, Xilinx and third-party tools, and the design implementation tools. This guide is a learning tool for designers who are unfamiliar with the features of the ISE software or those wanting to refresh their skills and knowledge. You may choose to follow one of the three tutorial flows available in this document. For information about the tutorial flows, see “Tutorial Flows.” Tutorial Contents This guide covers the following topics. • Chapter 1, “Overview of ISE and Synthesis Tools,” introduces you to the ISE primary user interface, Project Navigator, and the synthesis tools available for your design. • Chapter 2, “HDL-Based Design,” guides you through a typical HDL-based design procedure using a design of a runner’s stopwatch. • Chapter 3, “Schematic-Based Design,” explains many different facets of a schematic- based ISE design flow using a design of a runner’s stopwatch. This chapter also shows how to use ISE accessories such as StateCAD, CORE Generator™, and ISE Text Editor. • Chapter 4, “Behavioral Simulation,” explains how to simulate a design before design implementation to verify that the logic that you have created is correct. • Chapter 5, “Design Implementation,” describes how to Translate, Map, Place, Route (Fit for CPLDs), and generate a Bit file for designs. • Chapter 6, “Timing Simulation,” explains how to perform a timing simulation using the block and routing delay information from the routed design to give an accurate assessment of the behavior of the circuit under worst-case conditions. • Chapter 7, “iMPACT Tutorial” explains how to program a device with a newly created design using the IMPACT configuration tool. ISE 10.1 In-Depth Tutorial www.xilinx.com 3R Preface: About This Tutorial Tutorial Flows This document contains three tutorial flows. In this section, the three tutorial flows are outlined and briefly described, in order to help you determine which sequence of chapters applies to your needs. The tutorial flows include: • HDL Design Flow • Schematic Design Flow • Implementation-only Flow HDL Design Flow The HDL Design flow is as follows: • Chapter 2, “HDL-Based Design” • Chapter 4, “Behavioral Simulation” Note that although behavioral simulation is optional, it is strongly recommended in this tutorial flow. • Chapter 5, “Design Implementation” • Chapter 6, “Timing Simulation” Note that although timing simulation is optional, it is strongly recommended in this tutorial flow. • Chapter 7, “iMPACT Tutorial” Schematic Design Flow The Schematic Design flow is as follows: • Chapter 3, “Schematic-Based Design” • Chapter 4, “Behavioral Simulation” Note that although behavioral simulation is optional, it is strongly recommended in this tutorial flow. • Chapter 5, “Design Implementation” • Chapter 6,“Timing Simulation” Note that although timing simulation is optional, it is strongly recommended. • Chapter 7, “iMPACT Tutorial” Implementation-only Flow The Implementation-only flow is as follows: • Chapter 5, “Design Implementation” • Chapter 6, “Timing Simulation”ongly recommended in this tutorial flow. • Chapter 7, “iMPACT Tutorial” 4 www.xilinx.com ISE 10.1 In-Depth TutorialR Additional Resources Additional Resources To find additional documentation, see the Xilinx website at: http://www.xilinx.com/literature.
