Draw and annotate various kinds of timing diagrams in Tikz. There's no real documentation, read the source and the examples (diagrams-examples.tex), and use at your own risks ;-). The latest version is to be found here: https://gitorious.org/tikz-goodies/tikz-goodies You may want to have a look at tikz-timing too if you want to draw some hardware-oriented timing diagrams: http://www.texample.net/tikz/examples/tikz-timing/
