Abstract:
Method for combining logic-based circuit units and memory-based circuit units in a circuit arrangement, in which different supply voltage swings are provided, having the following steps:a) provision of at least one supply voltage potential for at least one logic-based circuit unit; b) provision of at least one ground potential for the logic-based circuit unit, in order thus to provide a supply voltage swing for the logic-based circuit unit; c) provision of at least one supply voltage potential for at least one memory-based circuit unit; d) provision of at least one ground potential for the memory-based circuit unit, in order thus to provide a supply voltage swing for the memory-based circuit unit; e) provision of a signal voltage swing, which is set between a signal voltage minimum value and a signal voltage maximum value and is applied both to the logic-based circuit unit and to the memory-based circuit unit; and f) setting of at least one ground potential difference between the at least one ground potential and a reference ground potential in such a way that the logic-based circuit unit and the memory-based circuit unit are supplied with at least one supply voltage swing, and that the signal voltage swing is provided without a supply voltage swing of the circuit units being exceeded, wherein the signal voltage swing in the case of logic-based circuit units is provided in the range between a signal voltage minimum value of 0.4 V and a signal voltage maximum value of 0.8 V.
