To enhance Xilinx CPLD designer productivity, Xilinx offers two free, leading edge, web powered software products. 

• Earlier this year, as part of the Silicon Xpresso initiative, Xilinx introduced the CPLD WebFITTER. This, industry first, interactive & on-line tool allows customers the ability to evaluate existing designs with our XC9500/XL/XV ISP CPLD families.
   
• To augment this tool, Xilinx now offers the WebPACK, two suites of free downloadable PC based design solutions that allow customers the ability to completely design, fit and program Xilinx XC9500 Series or Xilinx CoolRunner Series CPLD devices. 

Whether your design flow includes EDA tools like Synopsys, Synplicity or Exemplar, or you are looking for a complete design environment (including ABEL & HDL synthesis, fitting technology and programming software), WebFITTER and WebPACK allow the ultimate in flexibility.

Xilinx CPLD WebFITTER

Xilinx CPLD WebFITTER has broken new ground in the area of on-line silicon solution evaluation. By simply pointing to the design file and clicking the ‘GO’ button, you are moments away from the industry's best CPLD solution. Whether it's performance, cost or ease-of-use, the WebFITTER has it all.

WebFITTER features:

• Full fitting support for the XC9500 (5V), XC9500XL(3.3V) & XC9500XV (2.5V) devices.
• Accepts designs in VHDL, Verilog, ABEL, EDIF, XNF, TDF and NSR formats.
• Targets device via density, package, speed, voltage or automatic device selection.
• On-line price quotes

Once a design is submitted, the user is notified via email upon completion through the WebFITTER. A specific URL provides a comprehensive design evaluation summary page. Here, the user can quickly understand thier overall design statistics and device utilization.

WebFITTER provides:

• Links to fitting, timing and log files
• Targeted device datasheets
• On line XC9500 Series price quotes
• Simulation and device programming files
• Complete on-line HELP system
• On-line tutorials

Xilinx CPLD WebPACK

The Xilinx CPLD WebPACK contains FREE downloadable software solutions for Xilinx XC9500 Series and Xilinx CoolRunner CPLD design.  Each solution provides a simple and intuitive design environment for your target Xilinx CPLD family.

The Xilinx XC9500 Series CPLD WebPACK is a suite of three EDA design tools that can be downloaded and used individually or, when downloaded together become an integrated design environment for XC9500 Series CPLDs.

The Xilinx CoolRunner Series CPLD WebPACK includes two downloadable modules for the XPLA design entry and device programming software supporting all Xilinx CoolRunner Series CPLDs.

After downloading and installing this module, the Project Navigator will detect if any other WebPACK modules are present. Once installed the WebPACK modules will provide complete design implementation control from within a single project window.

By using the latest version of the ABEL compiler and simulator (V7.1) and Xilinx Synthesis Technology, coupled with the industry's most widely used project navigation system, Xilinx offers the latest in an integrated PC based CPLD design environment.

The Project Navigator can compile ABEL, VHDL or Verilog source files. ABEL vectors can be simulated and HDL testbenches can link to third party HDL simulation tools, like Model Technology. Once compiled, the netlist can be processed through the Xilinx CPLD implementation tools, seamlessly. The necessary JEDEC file will be created and the Project Navigator will invoke the JTAG Programmer for device programming and JTAG ‘INTEST’ verification using the same ABEL vectors from your design.

The XC9500 Device Fitter Tools module is identical to the Alliance Series v2.1i software currently available from Xilinx, just specific to the XC9500 CPLD families. This FREE downloadable module will accept either EDIF or XNF netlists and provide you with the JEDEC programming file and timing simulation netlist.
