Specification and Description Language

SDL is a compilable graphical language used to design event driven systems. The syntax is composed of two layers, the higher being a block based communication and the lower, a hybrid flowchart/finite state machine syntax.

SDL presentation Build a protocol in 30 minutes. No really. It's not a joke. Inception to simulation can be as short as 30 minutes. Just unzip and run sdldemo.html.
Prototype SDL editor It's just a prototype. You can't use it for work. This prototype was originally designed to demonstrate that SDL can be a bit more colorful than just black-and-white wire frame symbols.
Telelogic AB My critique on Telelogic AB, the biggest supplier of SDL tools. Did I mention I used to work for them?
