A semiconductor apparatus includes a mounting board, a system on chip (SOC) package and a memory package which are provided on the mounting board. The SOC package includes a semiconductor chip and a package substrate on which the semiconductor chip is mounted. The semiconductor apparatus further includes a signal wiring line through which a signal between the semiconductor chip and the memory package is transmitted, being provided on the package substrate and in the mounting board and a measurement terminal connected to the signal wiring line on main surface of the package substrate.
