Tools used in the design and verification of electronics have played a massive role in the dramatic evolution of these devices over the past few decades. After all, there is a limit to the amount of work and detail that even a good aerospace engineer can handle, but add the use of tools, and the sky (pun intended) is the limit.
While the use of state-of-the-art development tools has led to ever-increasing design complexity, the use of modern verification tools has, at the same time, made these complex designs more reliable. In addition, lifecycle management tools have facilitated the management of both the development process and data. All these types of tools have been essential in modern avionics development.
