CDL, or Computer Design (description) Language, was first reported by the author in 1965. Since then, there have been some changes and many versions of simulators for different computer systems. The language was created to bridge the gap between hardware and software designers. As such, it describes the computer elements and hardware algorithms at a level just above that of the electronics; this is the level commonly called the register transfer level.
