Latest Patents

Among his latest patents is a process for reducing cross-talk noise in VLSI circuits. This innovative process identifies a victim net in an integrated circuit and calculates a change in ground capacitance for the victim net to determine a noise amplitude that is less than or equal to a maximum allowable noise height. By selecting a cell or grouping of cells from a library that has an input capacitance closest to the change in ground capacitance, the process ensures that the noise amplitude remains within acceptable limits. Additionally, Buch has developed a method for rapid estimation of wire delays and capacitances based on the placement of cells. This method constructs a simple tree topology called a spine tree to connect the pins of the net, allowing for quick extraction of capacitance and computation of Elmore delays.
