  • Patent number: 9684756
    Abstract: Nets are assigned to wiring planes for generating a chip design. A computer is caused to execute a zero wire load timing session for a placed but unbufferred chip design. All nets of the chip design are set to a single wide wiring track without wiring plane assignments. A delta time delay is added to each sink of each of the nets to represent an estimated time of flight (TOF) delay. The nets wiring plane or width type for a particular pin is upgraded to a type having improved TOF characteristics. Each of the nets are compared against new predetermined slack and distance targets and new assigned wiring plane or width type determined to consume additional wiring track resources, and based on results, the upgrade is repeated or a design for session timing state for the nets is output to represent the unbufferred chip design.

  • Patent number: 8522187
    Abstract: A method to optimize performance of an electric circuit design is disclosed. The method comprises providing for each circuit element of the electric circuit design available design parameter options; transforming the electric circuit design and the design parameter options into a linear programming model; determining a solution for the linear programming model; and based on the solution generating a list of circuit elements which design parameters need to be changed to a different option to achieve performance optimization.

  • Publication number: 20030088395
    Abstract: The invention relates to a method and system for analyzing the dynamic behavior of an electrical circuit including a multiple layered power distribution system formed by a power grid and a plurality of electrical elements, said multiple layered power distribution system having at least two wiring layers providing a specified supply voltage level (U0) to each of said electrical elements, said analysis resulting in a representation that allows a judgment of whether or not the voltage level at any of said electrical elements might leave a predetermined voltage range under the condition that a predetermined number of said electrical elements are driven at the same time span.
