This paper reviews aspects of the field of design technology (also addressed as "computer aided design" or as "design automation") for electronic systems as it developed over the last 40 years. The point of observation is based in Europe. Yet it is the intention of the author to maintain a worldwide scope-for as much as he is able to do. We will look at the early computers and how they triggered the first experiments in solving electronic design problems. Then we will review the first attempts of circuit simulation and layout synthesis. This is followed by a description of design technology progress in the 1970s and the early 1980s. We continue with an interlude giving some historical background of the European social and industrial arena a...
