ABSTRACT:
A method is provided for designing a semiconductor chip having one or more functionally interfaced dynamic array sections. A virtual grate is laid out for conductive features used to define a gate electrode level of a dynamic array section. The virtual grate is defined by a framework of parallel lines defined at a substantially constant pitch. One or more conductive features are arranged along every line of the virtual grate. For each line of the virtual grate, a gap is defined between proximate ends of each pair of adjacent conductive features which are arranged along a common line of the virtual grate. Each gap is defined to maintain a substantially consistent separation between proximate ends of conductive features. Each conductive feature is defined to be devoid of a substantial change in direction, such that the conductive features remain substantially aligned to the framework of parallel lines of the virtual grate.
