A method for modifying an integrated circuit, the method comprising:
- providing an integrated circuit design comprising a plurality of circuit books having a first threshold voltage;
- and
- replacing at least one of the plurality of circuit books with at least one gate array book having a second threshold voltage that is lower than the first threshold voltage.
An integrated circuit comprising:
- at least one circuit book having a first threshold voltage;
- and
- at least one gate array book having a second threshold voltage, wherein the second threshold voltage is lower than the second threshold voltage.
An integrated circuit comprising:
- a gate array filler book region, the filler book region comprising at least a first region and a second region,
- wherein the first region comprises at least one first filler book having a first threshold voltage, the second region comprises at least one second filler book having a second threshold voltage, and the first threshold voltage is different than the second threshold voltage.
