Latest Patents
One of Kaufman's latest patents is titled "Method and apparatus for interconnect-driven optimization of integrated circuit design." This invention provides a method and apparatus for post-layout optimization of integrated circuits. It emphasizes local transformations achieved through incremental changes to placement and routing, thereby avoiding the costly design iteration loop that necessitates re-synthesis, re-placement, and re-routing. The optimization process can be executed in multiple phases, each accomplishing a specific set of transformations. Static timing analysis is conducted at the end of each phase to assess whether further optimization is needed. Initially, the physical design is scanned for mismatches between drivers and loads. In a subsequent phase, "hot spots" in the design are identified for local transformation using a "bidirectional combinational total negative slack" (BCTNS) algorithm. Further optimization phases focus on meeting setup and hold times in critical paths.
