ABSTRACT:
A hierarchical representation encapsulates the detailed internal composition of a sub-circuit using the notion of a cell definition (a CellDef). The CellDef serves as a natural unit for operational reuse. If the computation required for the analysis or manipulation (e.g. parasitic extraction, RET, design rule confirmation (DRC), or OPC) based on a CellDef or one cell instance can be applied, with no or minimal additional effort, to all or a significant subset of other instances of the cell, very substantial reduction in computational effort may be realized. Furthermore, a hierarchical representation also allows for the partitioning of the overall analysis/manipulation task into a collection of subtasks, e.g. one per CellDef. Multiple jobs may then be distributed across a large number of computational nodes on a network for concurrent execution. While this may not reduce the aggregate computational time, a major reduction in the overall turnaround time (TAT) is in itself extremely beneficial.
