  • Patent number: 7509598
    Abstract: Systems and methods are disclosed herein to provide software clock boosting techniques. For example in one embodiment, a method of configuring a programmable logic device includes receiving routed data; performing a software clock boost operation on the routed data to determine and include one or more desired clock delays for circuit elements. The software clock boost operation may include performing a static timing analysis on the routed data; determining a list of the desired clock delays; and modifying the routed data to insert the desired clock delays.

  • Patent number: 5922214
    Abstract: A method for fabricating thin film nanostructures is provided. A layer of material on a substrate is mechanically displaced using an atomic force microscopy tip. The displacement is carried out in a fluid containing molecules which rapidly enter the void created by the AFM tip and bind to the clean substrate surface. These molecules are spatially confined in the void created by the displacement and form inlaid structures within the surrounding material. The surrounding material can be removed to create islands of the new material. The method is particularly adapted for use in fabricating nanometer-scale microelectronic devices.
