Abstract: A welding stock storage rack made from wire mesh bent to form a pyramid has a trapezoidal cross section and planar, vertical ends. The wire mesh comprises elongate strands of steel wire laid in a rectangular grid and welded at each intersection to form a panel of regular, individual cells. Additional wire mesh forms end panels, completing a geometrically stable, three-dimensional structure. Welding stock of various types and sizes may be inserted longitudinally, transversely or both through the pyramid to be supported horizontally at various levels above the floor by opposing cells. Several of the racks may be concatenated end to end to form a longer rack for lengthier welding stock, and the racks may be nested when empty for inventorying, storage and transportation.

Abstract: An FPGA is laid out as a plurality of repeatable tiles, wherein the tiles are disposed in columns that extend from one side of the die to another side of the die, and wherein each column includes tiles primarily of one type. Because substantially all die area of a column is due to tiles of a single type, the width of the tiles of each column can be optimized and is largely independent of the size of the other types of tiles on the die. The confines of each type of tile can therefore be set to match the size of the circuitry of the tile. Rather than providing a ring of input/output blocks (IOBs) around the die periphery, IOB tiles are disposed in columns only. Where more than two columns worth of IOBs is required, more than two columns of IOB tiles can be provided.

Abstract: An integrated circuit (IC) includes multiple embedded test circuits that all include a ring oscillator coupled to a test load. The test load either is a direct short in the ring oscillator or else is a interconnect load that is representative of one of the interconnect layers in the IC. A model equation is defined for each embedded test circuit, with each model equation specifying the output delay of its associated embedded test circuit as a function of Front End OF the Line (FEOL) and Back End Of the Line (BEOL) parameters. The model equations are then solved for the various FEOL and BEOL parameters as functions of the test circuit output delays. Finally, measured output delay values are substituted in to these parameter equations to generate actual values for the various FEOL and BEOL parameters, thereby allowing any areas of concern to be quickly and accurately identified.
