Abstract
A semiconductor device provided with a replica circuit functioning as an equivalent circuit to that of a path configuration selected as a critical path in the semiconductor circuit and an adjustable delay device for example between an output side of the replica circuit and a phase comparator, the delay value of the delay device being adjustable after production of the chip to a value enabling the replica system including the replica circuit to reliably operate with a margin from the critical path delay of the semiconductor circuit, whereby it becomes possible to prevent setting of an excessive margin and becomes possible to increase the margin when the margin ends up smaller than expected and therefore it becomes possible to flexibly and efficiently configure the replica circuit, and a method of constitution of the same.
