Abstract
An integrated circuit implementation methodology uses mutable cells, e.g. cells that are capable of being personalized for use as one of a plurality of resource types. For example, a mutable cell is designed to have a component layout and a set of lower-layer internal connections compatible with both a design of a flip-flop, and a design of a pair of multiplexers. Independent customizations of the mutable cell, using higher layers of interconnect, efficiently use the cell as a flip-flop or as a pair of multiplexers. Use of mutable cells in an integrated circuit advantageously enables a set of predefined lower-layer photomask, such as for a predefined base array, to be efficiently shared among different applications. In some embodiments, a Simultaneous Dynamical Integration (SDI) Electronic Design Automation (EDA) flow advantageously uses mutable cells, such as to balance demand for resources against supply thereof.
