JTAG Programmer Guide

Preface

About This Manual

This manual describes Xilinx's JTAG Programmer software, a tool used for In-system progamming.

Before using this manual, you should be familiar with the operations that are common to all Xilinx's software tools: how to bring up the system, select a tool for use, specify operations, and manage design data. These topics are covered in the Development System Reference Guide.

Manual Contents

This manual covers the following topics.

• “Introduction” chapter describes JTAG Programmer software.
  
  
• “Hardware” chapter provides information for connecting and using the XChecker Serial Cable or the Parallel Download Cable for system operation.
  
  

• “JTAG Programmer Tutorial” chapter documents the basic tasks needed to download programming to XC9500 family devices in-system.
  
  
• “Designing Systems with FPGA's Enabled for Boundary-Scan Operations” chapter documents using the JTAG Programmer with FPGA devices.
  
  
• “Boundary Scan Basics” appendix contains reference information about boundary scan basics.
  
  
• “JTAG Parallel Download Cable Schematic” appendix has schematics for the XChecker Cable and the Parallel Download Cable.
  
  
• “Troubleshooting Guide” appendix contains troubleshooting information.
  
  
• “Error Messages” appendix provides a list of error messages that the JTAG Programmer may report. For most error messages a workaround is suggested.
  
  
• “Using the Command Line Interface” appendix documents the basics of using the JTAG Programmer from a command line in a workstation environment.
  
  
• “Standard Methodologies for Instantiating the BSCAN Symbol” appendix contains programming examples.
  
  

Conventions

This manual uses the following conventions. An example illustrates each convention.

• Courier font indicates messages, prompts, and program files that the system displays.
  
  speed grade: -100
  
  
• Courier bold indicates literal commands that you enter in a syntactical statement.
  
  rpt_del_net=
  
  Courier bold also indicates commands that you select from a menu.
  
  File Open
  
  
• Italic font denotes the following items.
  
  
  • Variables in a syntax statement for which you must supply values
    
    edif2ngd design_name
    
    
  • References to other manuals
    
    See the Development System Reference Guide for more information.
    
    
  • Emphasis in text
    
    If a wire is drawn so that it overlaps the pin of a symbol, the two nets are not connected.
    
    
• Square brackets “[ ]” indicate an optional entry or parameter. However, in bus specifications, such as bus [7:0], they are required.
  
  edif2ngd [option_name] design_name
  
  Square brackets also enclose footnotes in tables that are printed out as hardcopy in DynaText^®.
  
  
• Braces “{ }” enclose a list of items from which you choose one or more.
  
  lowpwr ={on|off}
  
  
• A vertical bar “|” separates items in a list of choices.
  
  symbol editor_name [bus|pins]
  
  
• A vertical ellipsis indicates repetitive material that has been omitted.
  
  IOB #1: Name = QOUT'
  IOB #2: Name = CLKIN'
  .
  .
  .
  
  
• A horizontal ellipsis “. . .” indicates that an item can be repeated one or more times.
  
  allow block block_name loc1 loc2 ... locn;
  
  

In addition, Xilinx has created several conventions for use within the DynaText online documents.

• Red-underlined text indicates an interbook link, which is a cross-reference to another book. Click on the red-underlined text to open the specified cross-reference.
  
  
• Blue-underlined text indicates an intrabook link, which is a cross-reference within a book. Click on the blue-underlined text to open the specified cross-reference.
  
  
• There are several types of icons.
  
  Iconized figures are identified by the figure icon.
  
  
  
  Iconized tables are identified by the table icon.
  
  
  
  The Copyright icon displays in the upper left corner on the first page of every Xilinx online document.
  
  
  
  The DynaText footnote icon displays next to the footnoted text.
  
  
  
  Double-click on these icons to display figures, tables, copyright information, or footnotes in a separate window.
  
  
• Inline figures display within the text of a document. You can display these figures in a separate window by clicking on the figure.
