PART 1 Introduction to Electronic Design Automation
The Need for Electronic Design Automation
The early integrated circuits were simple prising a small number of transistors and limited interconnect. Design
took place at the layout level by manually constructing the artwork for each layer using black tape on transparent sheets.
These were then photographed to produce the masks for fabrication.
As circuit densities began to increase it became apparent that some degree of automation would be needed to manage the
ever plexity inherent in the design process.
Three distinct groups of CAD tools emerged to assist in the management of plexity.
Design Entry Tools
Intel’s first microprocessor was drawn on paper sheets laid out on the floor of a rented aircraft hanger! An interesting
approach for a relative
