Large, complex circuits that can perform the logical operations required in a computer have been designed in many places for over three decades. Experience has shown that complex interconnection patterns are needed to implement the logic. The physical constraints of wiring technology must allow designers and design tools a large degree of choice among possible interconnection patterns. Certain generalizations concerning quantitative aspects of the interconnections have been recognized. Several of the empirical observations are reviewed and related where possible to models and used to illustrate trends. These generalizations give early guidance to design, and also may be regarded as targets against which designs may be measured. NOTE: FIGURES NOT INCLUDED IN PS FILE.
