Abstract
A method for configuring level shifter spare cells includes providing a power rail connectable to a corresponding power domain, and providing a spare cell including a level shifter circuit. The level shifter circuit has first and second terminals that are connectable to the power rail, and the first and second terminals are floating with respect to the power rail.
Claims10
An integrated circuit, comprising:
- at least one power rail connectable to a corresponding power domain, wherein the power domain has a power level;
- and
- at least one spare cell comprising a level shifter circuit, wherein the level shifter circuit has first and second terminals that are connectable to the at least one power rail,
- wherein the first and second terminals of the level shifter circuit are floating with respect to the at least one power rail.
1 more element
An integrated circuit having a plurality of power domains, comprising:
- multiple power rails each coupled with a corresponding one of the power domains and each having a corresponding power level;
- and
- multiple spare cells each comprising a level shifter circuit that can be coupled to one of the power rails at a first terminal, and to another of the power rails at a second terminal,
- wherein at least one of the power rails cannot be coupled to another power rail by way of the spare cells.
