Title: Weiqing Guo: Innovator in VLSI System Design
Introduction
Weiqing Guo is a prominent inventor based in Fremont, CA, known for his significant contributions to the field of Very Large Scale Integration (VLSI) systems. With a total of 8 patents, Guo has developed innovative methods that enhance the efficiency and reliability of integrated circuit designs.
Latest Patents
One of Guo's latest patents focuses on moment computation algorithms in VLSI systems. This improved method for interconnect delay analysis reduces a parasitic graph for moment computation by eliminating one or more nodes in the graph. The elimination process is based on the degree of the nodes, significantly reducing computation complexity. Additionally, this method can solve resistor loops and crossed loops. The order of node elimination is optimized using the depth-first-search method on parasitic graphs, further enhancing efficiency. This method also accounts for coupling capacitance between interconnects, providing a consistent functional interface applicable to various circuit model structures.
Another notable patent involves probabilistic noise analysis. This method determines whether voltage from an aggressor net exceeds a voltage threshold on a victim net design in integrated circuit design. The probabilistic noise from the aggressor net is calculated and checked against the voltage threshold. If the probabilistic noise exceeds the threshold, an effective noise at a desired mean time to failure is computed and checked against the voltage threshold. The victim net design is passed when the effective noise does not exceed the threshold, ensuring reliability in circuit performance.
