Abstract:
An apparatus for positioning a semiconductor integrated circuit device comprising analog and digital circuits, on a semiconductor substrate, comprising:(a) first means for designing said analog circuit;(b) second means for designing said digital circuit;(c) third means for designing a top hierarchy circuit;(d) fourth means for separating and combining data about connection among circuits designed by said first, second and third means;(e) fifth means for designing a layout of said analog circuit, based on data transmitted from said fourth means;(f) sixth means for extracting analog data from said fifth means, and transforming said analog data to digital data based on interface data that defines interfaces between said analog circuit and said digital circuit transmitted from said fourth means;(g) seventh means for designing a layout of said digital circuit, based on connection data of said digital circuit transmitted from said fourth means; and(h) eighth means for combining data about said layouts of said analog and digital circuits to each other to provide a one-chip layout.
