Structured Cell Analysis for ASIC Design Optimization

The patent applies universality by enabling structured cells to perform multiple functions through composite cell construction. Instead of limiting cells to primary components only, the invention combines multiple structured cells into composite cells that can implement various logic functions (AND, OR, NAND, NOR, XOR, etc.), making each physical cell structure serve multiple logical purposes and improving overall utilization efficiency

The patent implements nesting by creating composite cells that contain multiple nested structured cells within them. The composite cell structure allows smaller structured cells to be nested within a larger composite cell framework, enabling hierarchical organization where nested cells work together to implement complex logic functions while maintaining manufacturability through standardized cell structures

The patent applies preliminary action by pre-characterizing and pre-evaluating multiple structured cell candidates before actual system implementation. The system performs advance analysis of cell candidates, evaluating their logic function capabilities, area requirements, and performance characteristics upfront, so that when system design occurs, pre-validated composite cell configurations can be selected without extensive real-time analysis, improving productivity while managing complexity

The patent implements copying by creating standardized composite cell templates and logic function models that can be replicated and reused. Once cell candidates are evaluated and characterized, their performance data and logic function capabilities are copied into lookup tables and design libraries, allowing rapid selection and instantiation of optimized cell configurations without re-evaluating each candidate from scratch, thus improving productivity while maintaining manageable complexity
