PROGRAMMABLE LOGIC DESIGN: QUICK START HANDBOOK • CHAPTER 2

COOLRUNNER REFERENCE DESIGNS

CoolRunner reference designs are HDL code-based designs that can help reduce the time of CPLD designs. They are available free of charge.

These reference designs take the form of not-for-pay IP, which can be used as is. Unlike purchased IP, these reference designs do not come with direct support.

They are built around application notes and have been tested in WebPACK software. They are fully functional through the WebPACK simulator and testbench.

You can find CoolRunner reference designs in the Xilinx IP Center (http://www.xilinx.com/ipcenter/) by searching on the keyword “CoolRunner.”

Accessing the Reference Designs

From the Xilinx.com website, select “Products and Services” from the top bar and then select “Silicon Solutions.” Select “CoolRunner-II CPLDs” from the left-hand side bar and then select “CoolRunner Reference Designs.”

This will bring up a page that details all of the reference designs available for selection. Click on the application note that of interest and download the PDF file. Open the application and go to the last page of the document.
