Abstract

A circuit device includes plural semiconductor circuit devices that are formed on independent substrates, respectively, and communicate with each other. Each of the semiconductor circuit devices includes: plural modules of an identical type, functions of which are substitutable for one another; a module selecting unit that selects, among the plural modules, usable modules that are a part of the plural modules; and a circuit block including an interface unit for the modules selected by the module selecting unit to exchange signals with the other semiconductor circuit devices. A logic module included in one of the semiconductor circuit devices belongs to a different type, a function of which is not substitutable for a function of a logic module included in at least one of the other semiconductor circuit devices.
