Patent number: 7742315Abstract: The present invention relates to computer hardware design, and in particular to a printed circuit board (card) comprising wiring dedicated to supply electric board components such as integrated circuits with at least three different reference planes. In particular at locations, where the pins of a card-to-card connector enter the layer structure of the card discontinuities brake the high frequency signal return path of a given signal wiring. In order to close the signal return path around a signal path from card to card including the connector, and thus to limit the signal coupling while concurrently keeping the card design as simple as possible, it is proposed to provide a) an additional capacitance for a given signal wiring in a discontinuity section, b) wherein the additional capacitance is formed by a voltage island placed within a signal layer located next to the given signal wiring.Type: GrantFiled: November 17, 2005Date of Patent: June 22, 2010Assignee: International Business Machines CorporationInventors: Wiren D.

Patent number: 7503111Abstract: A method for increasing the wiring channels/density under dense via fields of a circuit board are provided. With the method, the power/ground lines for the circuit board are designed to be provided in an orthogonal or diagonal pattern. The land grid array (LGA)/ball grid array (BGA) makes contact only on the surface pads of the printed circuit board with no plated through holes/vias underneath these surface pads. This opens up wiring channels, which previously used to be occupied by plated through holes and anti-pads, that can now be used for maximizing signal line wiring routing.Type: GrantFiled: March 31, 2005Date of Patent: March 17, 2009Assignee: International Business Machines CorporationInventors: Anand Haridass, Dierk Kaller, Erich Klink, Gisbert Gerhard Thomke

Patent number: 7348667Abstract: A system and method for reducing noise in a multi-layer ceramic package are provided. With the system and method, additional shielding wires are inserted into the reference planes wherever there are no signal vias present. These additional lines in the reference planes force stronger signal interaction with the reference (vdd/gnd) thereby reducing the interaction between the signals in the signal layers. As a result, the noise present in the signals of the signal layers is reduced.Type: GrantFiled: March 22, 2005Date of Patent: March 25, 2008Assignee: International Business Machines CorporationInventors: Sungjun Chun, Jason Lee Frankel, Anand Haridass, Erich Klink, Brian Leslie Singletary

Patent number: 7302664Abstract: A system and method for automatic insertion of on-chip decoupling capacitors are provided. With the system and method, an integrated circuit design is partitioned into cells and the noise distribution per cell of an integrated circuit is determined. This noise distribution may be generated using any of a number of different known mechanisms and generally results in a noise-map being generated for the integrated circuit. Thereafter, a mapping function is applied to the noise map for each cell to determine a required capacitance for the cells of the integrated circuit. From this required capacitance per cell, the necessary decoupling capacitors may be identified as well as the location for insertion of these decoupling capacitors. In a similar manner, decoupling capacitors may be removed from cells of the integrated circuit based upon the determined required capacitance per cell.Type: GrantFiled: February 10, 2005Date of Patent: November 27, 2007Assignee: International Business Machines CorporationInventors: Anand Haridass, Andreas Huber, Erich Klink, Jochen Supper

Patent number: 7266788Abstract: A carrier for an electronic device such as an integrated circuit chip is designed by assigning two different voltage domains to two separate areas of the contact surface of the carrier, while providing a common electrical ground for both voltage domains. The integrated circuit chip may be a microprocessor having a nominal operating voltage, and the different voltages of the two voltage domains are both within the tolerance range of the nominal operating voltage but one of the voltage domains is aligned with a high power density area of the microprocessor (e.g., the microprocessor core) and provides a slightly greater voltage. The higher power voltage domain preferably has a ratio of voltage pins to ground pins that is greater than one.Type: GrantFiled: July 19, 2005Date of Patent: September 4, 2007Assignee: International Business Machines CorporationInventors: Anand Haridass, Andreas Huber, Erich Klink, Thomas Strach, Jochen Supper
