I would suggest registering with Xilinx and getting a license for the WebPACK software before obtaining the software as some countries may not be eligible for a license.
The DVD may also be included with a CPLD or FPGA kit. Ordering instructions are available on the Xilinx download page. The download is rather large, so if you have a slow Internet connection, you may need to order the DVD from Xilinx. The software can be obtained by downloading it from the Xilinx software download page or by ordering a DVD. All versions of the software, including the free version require you to register with Xilinx and obtain a license for the software.
