Abstract
An application specific integrated circuit which can develop a wide variety of integrated circuits in a short time period is provided. In respective functional blocks, inheritance circuits capable of holding and transferring function inheritance information necessary for univocally specifying functions of respective corresponding functional blocks, bearer switches serving as a data transfer switch, and program wiring mechanisms are provided. After a mother wafer on which such units are hierarchically connected by function inheritance information read-out buses is manufactured, function inheritance information is read out to obtain, on the basis of the read out information, information for connecting partial circuit groups within block having one-to-one correspondence with respect to that information to drive programmable wiring mechanisms by using such information, thus to obtain connections as defined be the system requirement specification.
