Abstract
A semiconductor integrated circuit device includes: a first semiconductor chip including a CPU and a debug basic circuit section for verifying operation of a program executed by the CPU; and a second semiconductor chip retained over a principal surface of the first semiconductor chip and including a debug extension circuit section electrically connected to the CPU and the debug basic circuit section. The debug basic circuit section includes a debug command analyzing section for analyzing a command input from outside. The debug extension circuit section formed in the second semiconductor chip includes a debugging function circuit section including at least one debug circuit.
