Programmable Logic DesignQuick Start Hand BookBy Karen Parnell & Nick MehtaJanuary 2002SecondEditionProgrammable Logic Design Quick Start Hand Book Page 2© XilinxABSTRACTWhether you design with discrete logic, base all of your designs onmicrocontrollers, or simply want to learn how to use the latest and mostadvanced programmable logic software, you will find this book aninteresting insight into a different way to design.Programmable logic devices were invented in the late seventies andsince then have proved to be very popular and are now one of thelargest growing sectors in the semiconductor industry. Why areprogrammable logic devices so widely used? Programmable logicdevices provide designers ultimate flexibility, time to market advantage,design integration, are easy to design with and can be reprogrammedtime and time again even in the field to upgrade system functionality.This book was written to complement the popular Xilinx CampusSeminar series but can also be used as a stand-alone tutorial andinformation source for the first of your many programmable logicdesigns. After you have finished your first design this book will proveuseful as a reference guide or quick start handbook.The book details the history of programmable logic, where and how touse them, how to install the free, full functioning design software (XilinxWebPACK ISE included with this book) and then guides you throughyour first of many designs. There are also sections on VHDL andschematic capture design entry and finally a data bank of usefulapplications examples.We hope you find the book practical, informative and above all easy touse.Karen Parnell & Nick MehtaProgrammable Logic Design Quick Start Hand Book Page 3© XilinxProgrammable Logic DesignQuick Start Hand BookProgrammable Logic Design Quick Start Hand Book Page 4© XilinxNAVIGATING THE BOOKThis report was written for both the professional engineer who has neverdesigned using programmable logic devices and for the new engineerembarking on their exciting career in electronics design. Toaccommodate this the following navigation section has been written tohelp the reader decide in advance which section he/she wishes to read.This chapter gives an overview of how and whereprogrammable logic devices are used. It gives abrief history of the programmable logic devicesand goes on to describe the different ways ofdesigning with PLDs.Chapter 2 describes the products and servicesoffered by Xilinx to ensure PLD designs enabletime to market advantage, design flexibility andsystem future proofing. The Xilinx portfolio includesboth CPLD & FPGA devices, design software,design services & support, and Cores.The WebPACK ISE design software offers acomplete design suite based on the XilinxFoundation ISE series software. This chapterdescribes how to install the software and whateach module does.Chapter 2XilinxSolutionsChapter 3WebPACKISE DesignSoftwareChapter 1IntroductionProgrammable Logic Design Quick Start Hand Book Page 5© XilinxNAVIGATING THE BOOK (Continued)This section is a step by step approach to yourfirst simple design. The following pages areintended to demonstrate the basic PLD designentry implementation process.This chapter discusses the Synthesis andimplementation process for FPGAs. The designtargets a Spartan IIE FPGA.This section takes the VHDL or Schematic designthrough to a working physical device. The design isthe same design as in the previous chapters buttargeting a CoolRunner CPLD.The final chapter contains a useful list of designexamples and applications that will give you a goodjump-start into your future programmable logicdesigns. It will also give you pointers on where tolook for and download code and search forIntellectual Property (IP) Cores from the Xilinx Web site.Chapter 4WebPACKISE DesignEntryChapter 5ImplementingFPGAsChapter 7DesignReferenceBankChapter 6ImplementingCPLDsProgrammable Logic Design Quick Start Hand Book Page 6© XilinxCONTENTSABSTRACTNAVIGATING THE BOOKCONTENTSABBREVIATIONSChapter 1 INTRODUCTION1.1 The History of Programmable Logic1.2 Complex Programmable LogicDevices (CPLDs)1.2.1 Why Use a CPLD?1.3 Field Programmable Gate Arrays(FPGAs)1.4 The Basic Design Process1.5 Intellectual Property (IP) Cores1.6 Design VerificationChapter 2 XILINX SOLUTIONS2.1 Introduction2.2 Xilinx Devices2.2.1 Platform FPGAs2.2.2 Virtex FPGAs2.2.3 Spartan FPGAs2.2.4 Xilinx CPLDs2.2.5 Military and Aerospace2.3 Design Tools2.4 Xilinx Intellectual Property (IP) Cores2.5 System SolutionsProgrammable Logic Design Quick Start Hand Book Page 7© XilinxCONTENTS (Continued)2.5.1 ESP EmergingStandards and Protocols2.5.2 Xtreme DSP2.5.3 Xilinx at Work2.5.4 Xilinx On Line2.5.5 Configuration Solutions2.5.6 Processor Central2.5.7 Memory Corner2.5.8 Wireless Connection2.5.9 Networking Connection2.5.10 Video and ImageProcessing2.5.11 Computers2.5.12 Communications andNetworking2.5.13 Education Services2.5.14 University Program2.5.15 Design Consultants2.5.16 Technical SupportChapter 3 WebPACK ISE DESIGNSOFTWARE3.1 Module Descriptions3.2 WebPACK CDROM InstallationInstructions3.3 Getting StartedProgrammable Logic Design Quick Start Hand Book Page 8© XilinxCONTENTS (Continued)Chapter 4 WebPACK ISE DESIGN ENTRY4.1 Creating a project4.2 VHDL Design Entry4.3 Functional Simulation4.4 State Machine Editor4.5 Top Level VHDL Designs4.6 Top Level Schematic DesignsChapter 5 IMPLEMENTING FPGAS5.1 Synthesis5.2 Constraints Editor5.3 Reports5.4 Timing Simulation5.5 ConfigurationChapter 6 IMPLEMENTING CPLDS6.1 Synthesis6.2 Constraints Editor6.3 Reports6.4 Timing Simulation6.5 ProgrammingChapter 7 DESIGN REFERENCE BANK7.1 Introduction7.2 Get the Most out of Microcontroller-Based Designs: Put a Xilinx CPLDOnboard7.3 Application Notes and Example Code7.4 Website ReferenceGLOSSARY OF TERMSProgrammable Logic Design Quick Start Hand Book Page 9© XilinxABBREVIATIONSABEL Advanced Boolean Expression LanguageASIC Application Specific Integrated CircuitASSP Application Specific Standard ProductATE Automatic Test EquipmentCDMA Code Division Multiple AccessCPLD Complex Programmable Logic DeviceCLB Configurable Logic BlockDES Data Encryption StandardDRAM Dynamic Random Access MemoryDSL Digital Subscriber LineDSP Digital
