Latest Patents
One of Lu Sha's latest patents is titled "Method and system for implementing an analytical wirelength formulation for unavailability of routing directions." This invention discloses methods and systems for formulating a wirelength estimate that considers the unavailability of certain routing directions. Under specific circumstances, some routing layers may not be available, and this invention addresses how to adjust the bounding box for accurate wirelength estimation.
Another significant patent is the "Non-linear optimization system and method for wire length and delay optimization for an automatic electronic circuit placer." This computer-implemented process automates the creation of IC geometry. It employs a general unconstrained non-linear optimization method to generate a coarse placement of cells on a 2-dimensional silicon chip or circuit board. The invention also includes features for automatically sizing cells, inserting buffers, and aiding in timing-driven structuring of the placed circuit. The master objective function (MOF) evaluates cell placement, while a conjugate-gradient process minimizes the MOF through optimization.
