摘要： One embodiment of the invention provides a multi-layered ceramic package. The ceramic package includes a signal layer having a plurality of signal lines and a mesh reference layer parallel to the signal layer. The mesh reference layer includes a plurality of intersecting reference lines of varying reference-line width in the plane of the mesh layer. The mesh reference lines may be widened in locations of probable signal cross-talk. Other embodiments of the invention include software for optimizing a ceramic package design by selectively widening mesh lines in regions of probable cross-talk, and systems for designing and manufacturing such a ceramic package.

摘要： A method, system, and computer program product for exploring and optimizing an electrical design space. A computer receiving a design space assigns a plurality of initial values (random or predetermined) for optimizing the design space. A particle swarm containing a plurality of particles is created and an optimization of the design space is then performed using the assigned initial values. Following completion of optimization, the global best and personal best for each particle are updated. Velocity vectors and position vectors of the design space are then updated before the computer performs the optimization process again. The process loops, continually updating global and personal bests and velocity and position vectors until a termination criteria is reached. Upon reaching the termination criteria, the best fitness of each particle of the swarm is assigned as an optimized design space. In an alternate embodiment, the particle with the worst target fitness may be assigned.

摘要： Systems and methods are provided that may be implemented in-situ and on-chip to capture a digital signal eye of a serial transmit signal produced by a transmitter circuit of integrated SerDes PHY transceiver circuitry. In one example, a serial transmit signal produced by a transmitter side circuit of an integrated SerDes PHY transceiver circuit may be looped back on chip to the receiver side circuit of the same SerDes PHY transceiver circuit such that an integrated digital eye monitor circuit of the SerDes receiver circuit may capture the digital eye of the serial transmit signal of the same SerDes PHY circuit. In another example, a digital eye monitor circuit may be integrated on the transmitter side of an integrated SerDes PHY transceiver circuit such that a serial transmit signal produced by the transmitter side circuit of may be captured on-chip.

摘要： A receiver circuit detects an eye margin within a differential signal having a true component and a complement component. A transmitter circuit adjusts a phase between the true component and the complement component of the differential signal, based on the eye margin, to improve the eye margin. Improving the eye margin results from a reduction in common mode noise within the differential signal.

摘要： A signal history controlled slew-rate transmission method and bus interface transmitter provide an improved channel equalization mechanism having low complexity. A variable slew-rate feed-forward pre-emphasis circuit changes the slew rate of the applied pre-emphasis in conformity with the history of the transmitted signal. The pre-emphasis circuit may be implemented by a pair of current sources supplying the output of the transmitter, and having differing current values. The current sources are controlled such that upon a signal value change, a high slew rate is provided and when the signal value does not change for two consecutive signal periods, the slew rate is reduced. A current source having a controlled magnitude may be employed to provide a slew rate that changes over time and is continuously reduced until another transmission value change occurs.
