Abstract

Modern design automation systems generally include a library of standardized mask images for complex logical functions which are composed of component images of more elementary logic functions. When the designer wishes to assemble several complex logic functions in designing a mask image for a large scale integrated circuit chip, the designer will select from the library those complex logic function images he desires and will instruct the design automation system to interconnect the functions in the circuit topology he desires. Frequently, the standardized image of the complex logic function includes more elementary functions than the designer may need for a particular application.
