Before the magic begins.. The Xilinx ISE is a powerful design suite for FPGAs/CPLDs manufactured by Xilinx. It consist of several tools that give possibility to design, debug, simulate and program the FPGAs. Unfortunately the Xilinx ISE is officially supported only on the one linux OS, namely, Rad Hat. However it does not mean that the Xilinx ISE would not work on other linux platforms, but requires additional postinstallation. The modifications, that you should make to force the tools work, depend on your OS and could be not trivial at all. The only help are tips'n'tricks on numerous FPGA forums and personal blogs, and I want to thank all of their authors. After spending of days for complete postinstallation I believe in importance of writing the following tutorial to save time of people that want to design FPGAs under linux. First, I want to clarify software versions and installing path I have used. So take into account, that you could have something differ

Many people consider Git to be too confusing or complex to be a choice for version control. Yet Git considers to grow in adoption, and many interesting things have grown up around it. This document is geared for someone wanted to get started with Git, often coming from a Subversion background. For most basic needs this document will cover 70 to 90 percent of your use. Getting Started To use Git you will have to setup a repository. You can take an existing directory to make a Git repository, or create an empty directory. To make your current directory a Git repository we simply run init . git init To make a new directory that is a Git repository we just specify a directory. git init newrepo From here on out we'll assume that you are in the root of the Git repository unless otherwise noted. Adding New Files So we have a repository, but nothing in it. You can add files with the add command. git add filename To add everything in your directory try git add . .

create a new repository create a new directory, open it and perform a git init to create a new git repository. checkout a repository create a working copy of a local repository by running the command git clone /path/to/repository when using a remote server, your command will be git clone username@host:/path/to/repository workflow your local repository consists of three "trees" maintained by git. the first one is your Working Directory which holds the actual files. the second one is the Index which acts as a staging area and finally the HEAD which points to the last commit you've made. add & commit You can propose changes (add it to the Index ) using git add <filename> git add * This is the first step in the b

For various reasons,you may want to use ISO images without burning them,and you just need to mount them in a easy way. First,create a directory which you want to mount ISO images to by running following command in terminal: sudo mkdir /media/ISOimage Then,add the loop module to your kernel,so it is possible to mount a compressed filesystem file: sudo modprobe loop Change directory where ISO images located: cd /iso-images-directory Now,use following command to mount ISO image: sudo mount iso-image-name.iso /media/ISOimage/ -t iso9660 -o loop replace “iso-image-name.iso”to your ISO image. And,use this command to umount ISO image: sudo umount /media/ISOimage
