EDA Tools Improve Through Programming Advances and User Feedback

There is no question that EDA tools are among the most important design aids for today’s engineers. Since the introduction of the earliest practical RF/microwave software in the 1980s, developers have been striving to make their products more accurate, easier to use, faster in their computation, and as comprehensive as possible. In the era before the personal computer, EDA tools—whether for high frequency design or general electron-ics—were limited in scope and speed, not to mention the limits on access due to the batch processes used for main-frame computers. Most of today’s senior engineers remember the time it took to create a deck of punch cards, wait for the results, and hope that there weren’t too manytyping mistakes that required another delivery of cards to the computer center and another wait for the results.
