Targeted optimization of buffer-tree logic

摘要

Computationally efficient methods and systems for optimizing an integrated circuit (IC) design by targeting only a limited subsection of buffer trees in the buffer system for optimization are provided. By making intelligent decisions about which buffer trees to optimize, greater gains in design efficiency (e.g., as measured by reduced delays and/or wire length) may be realized at greatly reduced computational times when compared to conventional techniques that attempt to optimize each buffer tree.
