Abstract: The present invention provides for a method and computer program product for handling timeout in a standard RPC connection. First, a client establishes a connection with a server with unique identification. After submitting an RPC request, the client system will periodically make secondary requests to the server to determine if the server is still actively processing the primary RPC request. If the secondary request is processed successfully and the server indicates that the primary request is still in progress, the client will continue to wait until either the primary request completes or enough time elapses to warrant another secondary request. The success of the secondary request hinges on finding a match of identification for the primary and secondary requests. If the secondary request fails, this failure is treated as a sign that there is either a network or a server problem, and the client is triggered into taking appropriate corrective action.

Abstract: The present disclosure is directed to a method of selecting cells in an integrated circuit for logic restructuring of an original design. The original design includes a set of parameters. The method includes forming a restructuring set that will include the selected cells for logic restructuring, and a candidate set. The restructuring set includes restructuring cells with an initial cell. The restructuring set is adapted to accept additional cells identified as restructuring cells. The candidate set is adapted to include candidate cells, where each candidate cell in the candidate set is connected to at least one of the restructuring cells in the restructuring set. The candidate set is adapted to remove candidate cells from the candidate set. The restructuring set is adapted to accept selected removed candidate cells as identified restructuring cells if a corresponding parameter is included in the set of parameters.

Abstract: A semiconductor package construction aimed at improving thermal performance. A heatspreader is provided having a metal alloy preform attached to it already. Then, a few dots of conductive epoxy are dispensed around the die. The heatspreader with the preformed metal alloy is pressed on the adhesive and then the part is cured. By coupling the die to the heatspreader with conductive epoxy, the die is constrained from warping. By removing the necessity of coating the die, the cost of fabrication is reduced. There is only a very marginal cost increase in the back end for dispensing the dots. For this, the process and equipment already exists in the backend. By reducing die backside warpage due, the die remains in good contact with the heatspreader, thus improving thermal performance.

Abstract: Creation and detection of synchronization marks for a multilevel data storage medium is disclosed.

A corresponding sequence may be generated by a detector and correlated with read data to detect the synchronization mark.

Abstract: Methods and structure for storing volume and other configuration information on all disk drives of a volume group and for performing pre-merge operations to inform a user of the pending availability of the identified volumes. Configuration information has been historically stored in two distinct areas of configuration information on disk drives—a volume information area and an “other” information area. Aspects of the invention provide for storing all configuration information in the “other” information area. All disks of a system therefore include all configuration information relating both to volumes and to pseudo volume. A pre-merge operation is performed when each disk drive is inserted into a storage system to present new volume information to a user. When the last disk drive of a volume group is inserted, the user may select new volumes to be imported into the system.

Abstract: A system for RTL test insertion in an integrated circuit layout pattern includes a core module, a test wrapper, and a smart wrapper. The core module describes a function defined by logical elements, interconnections between logical elements, input pins and output pins. The test wrapper is adapted to encapsulate the core module and to create test pins representing the core module. The smart wrapper is adapted to encapsulate the test wrapper and to assign the test pins to a non-asserted state. The smart wrapper is adapted to place an assertion on one or more of the test pins for static or dynamic testing of the integrated circuit layout pattern.

Abstract: A lithographic scanner collects surface height information concurrently with conducting a lithographic scan process. A defect identification module identifies wafers having a surface height metric greater than a determined threshold. The identified wafers may be separated for rework to correct the surface defects such as hotspots and improve manufacturing yield without requiring additional equipment. In one embodiment, the surface height metric is a maximum variation from a moving average surface height. In one embodiment, yield data is correlated with surface height information to determine a threshold value corresponding to defective circuit die.

Abstract: A method for determining component patterns of a raw substrate map. A subset of substrate patterns is selected from a set of substrate patterns, and combined into a composite substrate map. The substrate patterns are weighted. The composite substrate map is compared to the raw substrate map, and a degree of correlation between the composite substrate map and the raw substrate map is determined. The steps are iteratively repeated until the degree of correlation is at least a desired degree, and the weighted subset of substrate patterns is output as the component patterns of the raw substrate map.

Abstract: An improved method for interconnect delay analysis for VLSI circuits reduces a parasitic graph for moment computation by eliminating one or more nodes in the graph the elimination process is performed based upon the degree of the nodes. By eliminating nodes in this fashion, the computation complexity is significantly reduced. With this elimination process, resistor loops and crossed loops can also be solved. The order in which the nodes are eliminated is optimized using the depth-first-search method on the parasitic graphs, further reducing the computation complexity. The method provides a consistent functional interface, applicable to different circuit model structures. In addition, the method accounts for coupling capacitance between interconnects.
