An integrated circuit and method of generating a layout for an integrated circuit in which circuitry peripheral to an array of repetitive features, such as memory or logic cells, is realized according to devices constructed similarly as the cells themselves, in one or more structural levels. The distance over which proximity effects are caused in various levels is determined. Those proximity effect distances determine the number of those features to be repeated outside of and adjacent to the array for each level, within which the peripheral circuitry is constructed to match the construction of the repetitive features in the array.

Array-based integrated circuit with reduced proximity effects

A voltage level shifter with testable cascode devices is disclosed. According to one embodiment, the level shifter includes multiple cascode devices and switches a first output driver according to the values of a data input and an enable input. Testability devices coupled to cascode devices of the level shifter detect a current in response to failure of the corresponding cascode device.
