Layout overlap detection with selective flattening in computer implemented integrated circuit design

The present invention relates to a method for efficiently performing hierarchical design rules checks (DRC) and layout versus schematic comparison (LVS) on layout areas of an integrated circuit where cells overlap or where a cell and local geometry overlap. With the present invention, a hierarchical tree describes the integrated circuit's layout data including cells having parent-child relationships and including local geometry. The present invention performs efficient layout verification by performing LVS and DRC checking on the new portions of an integrated circuit design and layout areas containing overlapping cells. When instances of cells overlap, the present invention determines the overlap area using predefined data structures that divide each cell into an array of spatial bins. Each bin of a parent is examined to determine if two or more cell instances reside therein or if a cell instance and local geometry reside therein. Once overlap is detected, the areas of the layout data corresponding to the overlap areas are selectively flattened prior to proceeding to DRC and LVS processing. During selective flattening of the overlap areas, the hierarchical tree is traversed from the top cell down through intermediate nodes to the leaf nodes. Each time geometry data is located during the traversal, it is pushes directly to the top cell without being stored in intermediate locations. This provides an effective mechanism for selective flattening.

Access control for a packet-oriented network, taking into account resilience requirements

The invention relates to a method for providing resources for adapting the routing process in response to the failure of a network element in a packet-oriented network. Barring checks that use thresholds are provided to control the volume of traffic in the network. Data packets are barred if their routing would otherwise mean the crossing of a threshold. According to the invention, the thresholds are defined by taking into account failure topologies or possible malfunction scenarios, to ensure that a corresponding malfunction does not lead to an overload in the network. Said definition of the thresholds allows resources to be provided or reserved to all intents and purposes for intercepting malfunctions. The advantage of the invention is that quality criteria can be upheld and quality of service features guaranteed, even during the malfunctions.

Data storage method and apparatus utilizing evolution and hashing

Hashing functions have many practical applications in data storage and retrieval. Perfect hashing functions are extremely difficult to find, especially if the data set is large and without large-scale structure. There are great rewards for finding good hashing functions, considering the savings in computational time such functions provide, and much effort has been expended in this search. This in mind, we present a strong competitive evolutionary method to locate efficient hashing functions for specific data sets by sampling and evolving from the set of polynomials over the ring of integers mod n. We find favorable results that seem to indicate the power and usefulness of evolutionary methods in this search. Polynomials thus generated are found to have consistently better collision frequencies than other hashing methods. This results in a reduction in average number of array probes per data element hashed by a factor of two. Presented herein is an evolutionary algorithm to locate efficient hashing functions for specific data sets. Polynomials are used to investigate and evaluate various evolutionary strategies. Populations of random polynomials are generated, and then selection and mutation serve to eliminate unfit polynomials. The results are favorable and indicate the power and usefulness of evolutionary methods in hashing. The average number of collisions using the algorithm presented herein is about one-half of the number of collisions using other hashing methods. Efficient methods of data storage and retrieval are essential to today's information economy. Despite the cur-rent obstacles to creating efficient hashing functions, hashing is widely used due to its efficient data access. This study investigates the feasibility of overcoming such obstacles through the application of Darwin's ideas by modeling the basic principles of biological evolution in a computer. Polynomials over Zn are the evolutionary units and it is believed that competition and selection based on performance would locate polynomials that make efficient hashing functions.
