In this paper, the authors propose a scheme to verify a wiring route for connecting an analog circuit, a digital circuit, and both the circuits in a hybrid semiconductor integrated circuit.Abstract:
PROBLEM TO BE SOLVED: To verify a wiring route for connecting an analog circuit, a digital circuit and both the circuits in a hybrid semiconductor integrated circuit. SOLUTION: The hybrid semiconductor integrated circuit C0 for inputting an output signal of a digital circuit C1 to an analog circuit C2 comprises first selectors F0 to F7 for switching the signal of the circuit C1 and signals from external terminals TI0 to TI7 by a mode switching signal S0 to input it to the circuit C2, and a selector F8 for switching outputs of an analog signal processor D0 for constituting the circuit C2 and a P-s conversion block DS1 to output it to an exterior. Second external terminals TO0 to TO7 are connected to the output of the first selector. Thus, the wiring route for connecting the circuit C2 to the circuit C1 and the external terminal are selectively connected to verify an independent operation of both the circuits and the route.read more

Semiconductor Integrated Circuit Device
TL;DR: In this article, a low-voltage control without largely increasing the circuit layout area in a low power consumption structure is presented. But the authors focus on the case of low-speed control, where the region operates on voltages between a power supply voltage and a virtual reference potential.
