    摘要: Serial high speed interconnect devices are integrated with semiconductor devices to reduce the number of input-output pins required for communications and control between a plurality of semiconductor devices. The serial high speed interconnect devices transfer the data serially at a rate fast enough to replace large parallel data and address buses that require one conductive path per bit of data. Eliminating large parallel data and address buses allows the integrated circuit assembly containing the semiconductor device to be smaller, simpler and lower in cost. The subsequent reduction in the size of the integrated circuits improves the layout density of electronic systems and reduces crosstalk and other undesirable signal transfer anomalies. The serial high speed interconnection devices are implemented with a low cost serial interface logic technology that may be easily implemented on a semiconductor die in conjunction with the main logic circuits.

    摘要: A methodology for generating structural descriptions of complex digital devices from high-level descriptions and specifications is disclosed. The methodology uses a systematic technique to map and enforce consistency of the semantics imbedded in the intent of the original, high-level descriptions. The design activity is essentially a series of transformations operating upon various levels of design representations. At each level, the intended meaning (semantics) and formal software manipulations are captured to derive a more detailed level describing hardware meeting the design goals. Important features of the methodology are: capturing the users concepts, intent, specification, descriptions, constraints and trade-offs; architectural partitioning; what-if analysis at a high level; sizing estimation; timing estimation; architectural trade-off; conceptual design with implementation estimation; and timing closure. The methodology includes using estimators, based on data gathered over a number of realized designs, for partitioning and evaluating a design prior to logic synthesis. From the structural description, a physical implementation of the device is readily realized.Techniques are described for estimating the power and area requirements of the physical implementation of the device, at early, high level stages of the design process (e.g., at the system, behavioral, and register transfer level stages). The techniques are suited to the design of any semiconductor device, particularly CMOS devices.

The methodology includes using estimators, based on data gathered over a number of realized designs, for partitioning and evaluating a design prior to logic synthesis. From the structural description, a physical implementation of the device is readily realized. Techniques are provided for constraint-driven partitioning of behavioral descriptions, and effective partitioning of high level descriptions for synthesis of multiple chips or blocks at the logic or register transfer levels. The partitioning technique is level-independent, and is integrated with the top-down design process, and takes into account constraints such as area, timing, power, package cost and testability. Iterative refinement is used to arrive at partitions that meet constraints imposed at high levels of abstraction.

    摘要: Signals (including probes) from an external system are selectively connected to a plurality of unsingulated dies on a semiconductor wafer with a minimum number of connections and an electronic selection mechanism resident on the wafer. The electronic selection mechanism is connected to the individual dies by conductive lines on the wafer. The electronic selection mechanism is capable of providing the external signals (or connecting the external probe) to a single die or groups of the dies, and electronically "walking through" the entire plurality of unsingulated dies. Redundant conductive lines may be provided. Diodes and/or fuses may be provided in conjunction with the conductive lines, to protect against various faults which may occur in the conductive lines. Redundant electronic selection mechanisms may also be provided to ensure the ability to selectively provide signals to the unsingulated dies.

    摘要: A semiconductor package is described which has external connection points (pins, pads, etc.) which may be configured from outside of the package. In one embodiment, this is accomplished with programming holes which pass through and form contact surfaces with various conductors within the package. Conductive material is then deposited into selected holes, forming connections between all of the contact surfaces in any hole. In another embodiment, configurability is accomplished via conductive pads disposed on the exterior surface of the package. Conductive jumpers are then used to connect selected pads. An auxiliary externally effected power plane and bus-bar structure are also described.

    摘要: A system for interactive design, synthesis and simulation of an electronic system allowing a user to design a system either by specification of a behavioral model in a high level language such as VHDL or by graphical entry. The user can view full or partial simulation and design results simultaneously, on a single display window. The synthesis process uses a systematic technique to map and enforce consistency of the semantics imbedded in the intent of the original, high-level descriptions. The design activity is generally a series of transformations operating upon various levels of design representations. At each level, the design can be simulated and reviewed in schematic diagram form. The simulation results can be displayed immediately adjacent to signal lines on the diagram to which they correspond. In one embodiment, design rule violations are processed by an expert system to suggest possible corrections or alterations to the design which will eliminate the design rule violations. Schematic diagram and simulation displays showing those portions of the electronic system and simulated signal patterns which are related to the design rule violations are used to help the user identify and appropriately correct problems in the design.

    摘要: Content Addressable Memory (CAM) core is integrated and interfaced with a configurable logic core (e.g., FPGA) on a single integrated circuit (IC) chip to permit a user to change algorithms for and to tailor word length to a particular application. Significant improvements in fetch times and overhead are achieved. An electronic component (e.g., integrated circuit) incorporating the technique is suitably included in a system or subsystem having electrical functionality, such as general purpose computers, telecommunications devices, and the like.
