  • Method for layout generation with constrained hypergraph partitioning
    Patent number: 10509883
    Abstract: A layout-generation method for an IC is provided. The layout-generation method includes accessing data of a schematic design of the IC; generating a hypergraph from the schematic design; transforming a plurality of constraints into a plurality of weighted edges in the hypergraph; continuing partitioning the hypergraph by the weighted edges until a plurality of multilevel groups are obtained to generate a layout; and verifying the layout to fabricate the IC.

  • Efficient analog layout prototyping by layout reuse with routing preservation
    Patent number: 10409943
    Abstract: A computer implemented method for routing preservation is presented. The method includes decomposing, using the computer, a geometric relationship between a first module, a second module, and a routing path of a source layout, when the computer is invoked to route the solution path. The method further includes disposing, using the computer, the routing path in a solution layout in accordance with the geometric relationship. The solution layout is not defined by a scaling of the source layout.
