Patent number: 7506276Abstract: A method of modifying an integrated circuit design. A noise threshold is determined. A threshold, noisy wire length for a particular integrated circuit design is selected. An integrated circuit design is examined for problem networks or wires and all branches that cumulatively equal or exceed the designated threshold noisy wire length. Once the problem networks are identified, the driver circuits driving the problem networks are temporarily replaced with driver circuits with lesser driving capacity. The integrated circuit design is then tested and any new timing failures are identified. Networks that include new timing failures are isolated with symmetric and/or asymmetric wire configurations. This method of modifying an integrated circuit design is non-intrusive to existing neighboring wires, and thus the timing in existing wires is preserved.Type: GrantFiled: May 26, 2005Date of Patent: March 17, 2009Assignee: International Business Machines CorporationInventors: Thomas Charles Brennan, Todd Alan Greenfield

Publication number: 20060168020Abstract: A service for protecting the privacy of domain name registrants while preserving the registrant's ability to directly change the registration information or transfer the registration. A whois record is created that reflects the registrant's actual identity but contains contact information that is entirely associated with a privacy service.Type: ApplicationFiled: December 10, 2004Publication date: July 27, 2006Inventor: Charles Brennan

Patent number: 6848480Abstract: A method for filling a dual fluid cartridge assembly which automatically bleeds air from the cartridge to filling and without extra steps or a vacuum as in known filling methods. In particular, the process relates to providing a dual fluid cartridge assembly which includes vents that bleed air from the cartridges initially and automatically closes the vents as the piston seal moves away from the vent. By utilizing such a self-bleeding cartridge assembly, the cartridge can be filled by a fluid dispenser without the need for shims, a vacuum or bleed plugs.Type: GrantFiled: January 12, 2004Date of Patent: February 1, 2005Assignee: TAH Industries, Inc.Inventor: Robert Charles Brennan

Patent number: 6715133Abstract: A method is shown which replaces single vias with redundant vias on candidate signals on a semiconductor integrated circuit chip. Where limited space prevents such replacement on more than one signal wire, the method assigns priority to the via through which more current must flow to charge or discharge capacitance. This prioritization reduces the magnitude of delay anomalies arising from vias containing process related resistance defects.Type: GrantFiled: January 16, 2003Date of Patent: March 30, 2004Assignee: International Business Machines CorporationInventor: Thomas Charles Brennan

Patent number: 6434731Abstract: An automated method for designing a signal distribution network in an integrated circuit confines the circuits relating to a particular signal, such as a clock signal, to multiple areas equally distributed over the integrated circuit. Each of the multiple areas have tightly-coupled logic connected to a root driver circuit in which the root driver circuit is connected to the signal input. Within the areas of tightly-coupled logic, user-defined placement circuits or groups such as a programmable clock delay having gates, delays, and splitters are connected to the root driver circuit in accordance with wire capacitance targets and input pin load balancing among all the multiple areas. The input pin load balancing and the wire capacitance targets of the user-defined placement groups connected to the root driver circuit in one of the multiple areas matches the input pin load balancing and the wire capacitance targets of other groups connected to other root driver circuits in other multiple areas.Type: GrantFiled: October 26, 1999Date of Patent: August 13, 2002Assignee: International Business Machines CorporationInventors: Thomas Charles Brennan, Kevin Charles Gower, Daniel John Kolor, Erik Victor Kusko
