Abstract: A voltage regulator arrangement having a first voltage regulator, whose input connection is connected to the supply potential connection and whose output connection is connected to a first supply potential connection of a circuit arrangement, with the first voltage regulator supplying the circuit arrangement with a supply voltage in a rest state. A second voltage regulator is also provided, whose input connection is connected to the supply potential connection, and whose output connection is connected to a second supply potential connection of the circuit arrangement, with the second voltage regulator supplying the circuit arrangement with a supply voltage during its normal operation.

Abstract: A technique for checking a layout design of an integrated circuit is disclosed. The technique has application to converting the design of a circuit from schematic to layout form. Instances where multiple pwell isolation tanks are coupled to the same node and where one or more pwell isolation tanks are shorted to a substrate are detected. Node breakers are inserted in the layout between pwell isolation tanks coupled to the same node and between the substrate and isolated pwell tanks coupled to the substrate. The node breakers are inserted in the circuit schematic as well to satisfy a layout versus schematic comparison. Inserting the node breakers highlights circuit component groupings as well as which tanks contain certain elements, if any. This allows designers to make a conscious decision as to the location and groupings of elements in a layout design.
