Digital and Analog Electronic Design Automation

The field of design automation (DA) technology, also commonly called computer-aided design (CAD) or computer-aided engineering (CAE), involves developing computer programs to conduct portions of product design and manufacturing on behalf of the designer. Competitive pressures to produce more efficiently new generations of products having improved function and performance are motivating the growing importance of DA. The increasing complexities of microelectronic technology, shown in Fig. 34.1, illustrate the importance of. | Dewey A.

Competitive pressures to produce more efficiently new generations of products having improved function and performance are motivating the growing importance of DA. The increasing complexities of microelectronic technology shown in Fig. 34.1 illustrate the importance of relegating portions of product development to computer automation Barbe 1980 . Advances in microelectronic technology enable over 1 million devices to be manufactured on an integrated circuit that is smaller than a postage stamp yet the ability to exploit this capability remains a challenge. Manual design techniques are unable to keep pace with product design cycle demands and are being replaced by automated design techniques Saprio 1986 Dillinger 1988 . Figure 34.2 summarizes the historical development of DA technology. DA computer programs are often simply called applications or tools. DA efforts started in the early 1960s as academic research projects and captive industrial programs these efforts focused on tools for physical and logical design. Follow-on developments extended logic simulation to more-detailed circuit and device simulation and more-abstract functional simulation. Starting in the mid to late 1970s new areas of test and synthesis emerged and vendors started offering commercial DA products. Today the electronic .
