Xilinx 13.1 Software Free Download
Xilinx ISE Design Suite 14.7 was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The program lies within Photo & Graphics Tools, more precisely 3D Design.

We cannot guarantee that the program is safe to download as it will be downloaded from the developer's website. Before launching the program, check it with any free antivirus software. This program was originally created by Xilinx Inc. The most popular versions among Xilinx ISE Design Suite users are 14.7, 13.4 and 13.3.
The Web Edition is the free version of Xilinx ISE, that can be downloaded and used for no charge. It provides synthesis and programming for a limited number of Xilinx devices. In particular, devices with a large number of I/O pins and large gate matrices are disabled.
In addition to previous comment I like to mention that the RTL viewer error in the Mux 4to2 encoder probably is at the Equal0 symbol that has 4'h1 for marking which if I'm not mistaken should be 4'h8 instead? I do not know if these errors are patched after the upgrade is done but sadly the upgrade can't be downloaded without the already installed Quartus 13.1 edition connected to the internet. Why I need an offline upgrade
Please upgrade the design to the latest version of the Intel Quartus Prime Lite edition software as some of the bugs in the older version are fixed in the later version. You may download the latest software using another internet connected PC and install in your current PC.
Thank you KhaiY, but I can't do that because I need my Quartus II 13.1 version because of still supporting the older Spartan 3 FPGA's. Yesterday I was not being able to download the upgrade files for version 13.1 because they seemed hidden somehow.
