    摘要: An improved integrated circuit cell architecture is provided for configurability between a memory cell or logic elements. The cell architecture is configured on variable layers above a first layer of metal, with the first layer of metal and layers therebelow reserved as fixed layers. By coupling a maximum of two layout cells together, a single-port or dual-port memory cell is realized. Likewise, by interconnecting transistors within a single cell or transistors among two or more cells, a logic device is realized. Within each cell, the bit lines are arranged on a layer separate from the wordlines, and extend orthogonal to each other.

The dielectric barrier stack includes a first portion formed adjacent to the copper layer and a second portion formed on the first portion, the first portion having improved adhesion to copper relative to the second portion and both portions are formed having resistance to copper diffusion. The invention also includes several embodiments for constructing such structures. Adhesion of the dielectric barrier stack to copper can be increased by plasma treating or ion implanting selected portions of the dielectric barrier stack with adhesion enhancing materials to increase the concentration of such materials in the stack.

    摘要: A clock pulse controller includes a test clock pulse input for receiving test clock pulses. A scan enable input receives a scan enable signal having a first state and a second state. A trigger pulse input receives a trigger pulse. A clock pulse output generates a launch clock pulse and a capture clock pulse from the test clock pulses immediately after receiving a predetermined number of the test clock pulses immediately following the trigger pulse. A delayed scan enable output generates a delayed scan enable signal that transitions from the first state to the second state between a leading edge of the launch clock pulse and a leading edge of the capture clock pulse.

    摘要: The present invention is directed to methods for defining and naming iSCSI targets using volume access and security policy. In an exemplary aspect of the present invention, a method for defining an iSCSI target using volume access and security policy may include the following steps. One or more volumes of a network entity may be first mapped to an initiator. The mapping defines the unique Logical Unit Number for the volume to an initiator. Then, a security level may be defined for access to each volume accessed by the initiator. The subset of mappings for each initiator may be given any unique name. Next, the mapping and security subsets may be used to define the fully qualified targets with which the initiator may open a session.

    摘要: A process is provided, which includes receiving geometrical information for a plurality of layers of an electronic structure within at least one output data file from an electronic structure design tool. At least one numerical analysis data file is created from the output data file, which contains the geometrical information and has a file structure compatible with a numerical analysis tool for characterizing the electronic structure. The numerical analysis tool is used to read the numerical analysis data file and generate a three-dimensional meshed geometric model of the electronic structure from the numerical analysis data file, wherein the model includes three-dimensional geometric models of each layer. The model can then be used, for example, to solve numerical thermal, mechanical or electrical equations that are applied to the model.

    摘要: A method and computer program for static timing analysis includes receiving as input minimum and maximum stage delays for two corners of an integrated circuit design. A path slack for a setup timing check is calculated from the minimum and maximum stage delays as a function of net clock cycle interval T_clk, launch path delay T_LP, capture path delay T_CP, data path delay T_DP, and a first delay de-rating factor Y1. A path slack for a hold timing check is calculated from the minimum and maximum stage delays as a function of the launch path delay T_LP, the capture path delay T_CP, the data path delay T_DP, and a second delay de-rating factor Y2. The path slack calculated for the setup timing check and for the hold timing check is generated as output.

    摘要: A combination of an infrequently-called tiny multiplication unit and a “differential” unit that quickly computes T (n+1) basing on known T n. The schedule (how often the multiplication unit is called) can be considered as a parameter of the algorithm. The proposed architecture of the “differential” unit is efficient both in terms of speed (delay) and area (gate count).
