Title: Subhasis Bose: Innovator in Integrated Circuit Design
Introduction
Subhasis Bose is a prominent inventor based in Austin, TX (US), known for his contributions to the field of integrated circuit design. He holds a total of 7 patents, showcasing his innovative approach to technology and engineering.
Latest Patents
His latest patents include methods and systems for placement and routing of integrated circuit elements. These techniques encompass global placement, detailed placement, timing closure, and routing. The integrated circuit is described by a netlist that specifies the interconnections of morphable devices. The detailed placement utilizes Simultaneous Dynamical Integration, where the morphable devices correspond to nodes influenced by various forces, including timing forces. These timing forces are derived from a timing graph, path delay, slack, and drive resistance of the elements. The timing closure employs timing-driven buffering and resizing to minimize maximum delay and transition time, as well as to address hold time issues. Nets with high capacitance and timing-critical nets are processed preferentially. Timing-driven buffering applies solutions to segments of route trees, combines solutions of adjoining segments, and prunes sets of solutions. Additionally, timing-driven resizing morphably replaces selected elements with larger versions.
Another significant patent involves node spreading via artificial density enhancement to reduce routing congestion. This patent applies Simultaneous Dynamical Integration modeling techniques to the global placement of integrated circuit elements, as described by netlists. Solutions to a system of coupled ordinary differential equations, in accordance with Newtonian mechanics, are approximated through numerical integration. The resultant time-evolving system of nodes moves through a continuous location space in continuous time, which is used to derive placements of the morphable devices that correspond one-to-one with the nodes. Nodes influenced by net attractive forces, computed based on interconnections between morphable devices, tend to coalesce into organized topologies. Furthermore, nodes are affected by spreading forces determined by density fields developed from local spatial node populations.
