`
`I. OVERVIEW
`
`An application specific integrated circuit (ASIC) can be defined in the
`broadest sense as an IC designed for a particular application or end-use
`such as in a compact disc player or a telecommunications system. ASICs
`stand in sharp contrast to standard IC products such as memories or
`microprocessors which are typically designed for use in a wide range of
`applications. In addition to being a class ofiC products, ASICs also define
`a design style 9r methodology which is based on the extensive use of
`computer-aided design (CAD) tools and systems. ASICs are typically de(cid:173)
`signed, at least in part, by someone other than the semiconductor vendor's
`personnel. Most often, the designer is the customer. This fact, coupled with
`differences in design objectives such as performance, area, and time to
`market, further differentiates ASICs from other types of IC designs. ASICs
`have driven an expansion of the semiconductor industry, have fundamen(cid:173)
`tally altered the IC business, and have resulted in a significant increase in
`the number of IC designs and designers. The rapid growth of ASICs has

`
`required advances in a number of different areas of semiconductor tech(cid:173)
`nology including design, process, manufacturing, test, packaging, and
`CAD. Widespread utilization and the rapid evolution of ASIC technology
`are expected to continue in the 1990s. Integrated Circuit Engineering of
`Scottsdale, Arizona predicts that the worldwide merchant market for
`ASICs will more than double between 1988 and 1993, that one out of every
`five dollars spent on all types of ICs in 1993 will be devoted to ASICs, and
`that in 1993 over half of the logic market will be ASICs [ 1]. These predic(cid:173)
`tions of growth clearly indicate the rapidly increasing importance of ASICs
`in the IC and electronic systems marketplaces.
`
`A. Historical Perspective
`
`The history of ASICs can be traced back more than 20 years to the
`masked read-only memory (ROM). Gate arrays and standard cells came
`into existence in the 1970s. However, it was during the decade of the 1980s
`that ASIC technology really assumed an important leading edge position in
`the worldwide IC marketplace. During the 1980s, numerous new merchant
`semiconductor vendors specializing in ASICs came into existence, and
`established broad line suppliers entered the ASIC business. By the end of
`the decade, Japanese semiconductor vendors had established a dominant
`position in the ASIC marketplace. For example, in 1988, 55% of the
`world's CMOS gate array designs were done in Japan as compared to 35%
`done by U.S. suppliers, and in 1989, Japanese firms took half of all
`merchant and captive gate array design wins [2]. By 1990, several broad
`line U.S. suppliers had re-thought or abandoned their ASIC strategies after
`finding the job-shop and service nature of the ASIC business difficult to
`integrate with more traditional high-volume approaches. Nevertheless,
`many U.S. vendors including both ASIC "specialists" and broad line
`suppliers are continuing to compete very effectively in the highly aggressive
`ASIC marketplace.
`
`B. Classification of ASICs
`
`The history of ASIC technology can be characterized by the evolution
`and proliferation of ASIC design styles [3]. Although CMOS gate arrays
`have been dominant, numerous other types of ASICs have been brought to
`market in the past several years. One possible representative classification
`of ASICs is presented in Fig. 1. As shoWn in the figure, ASICs can be
`grouped into four broad categories: (1) full-custom, (2) semi-custom, (3)
`field-programmable logic devices (FPLDs), and (4) linear arrays.
`The semi-custom category of Fig. 1 includes those types of devices which
`are most often equated with ASICs: gate arrays and cell-based ICs. The first
