A software model of a stacked integrated circuit system includes a first integrated circuit die connected to a second integrated circuit die through an interchip communication interface. The process includes the operation of blocking by the first processor of completion by a second processor of a configuration cycle. The mirror has a reflecting film formed by depositing reflecting material onto a transparent substrate, and a circular-ring light guiding portion made of transparent material. The calculated areas may be displayed to a clinician. The passive component is disposed within a cavity portion formed on an upper surface of the substrate and the semiconductor device is disposed across the cavity portion of the substrate above the passive component.
