Patent number: 7917795Abstract: A method, an apparatus, and a computer program are provided to measure and/or correct duty cycles. Duty cycles of various signals, specifically clocking signals, are important. However, measurement of very high frequency signals, off-chip, and in a laboratory environment can be very difficult and present numerous problems. To combat problems associated with making off-chip measurements and adjustments of signal duty cycles, comparisons are made between input signals and divided input signals that allow for easy measurement and adjustment of on-chip signals, including clocking signals.Type: GrantFiled: January 15, 2008Date of Patent: March 29, 2011Assignee: International Business Machines CorporationInventors: David William Boerstler, Eskinder Hailu, Byron Lee Krauter, Kazuhiko Miki, Jieming Qi

Patent number: 7519498Abstract: The present invention provides a method, an apparatus, and a computer program product for measuring the temperature of a microprocessor through the use of ESD circuitry. The present invention uses diodes and an I/O pad within ESD circuits to determine the temperature at the location of the ESD circuitry. First, a current measuring device connects to a diode. A user or a computer program disables the protected component or circuitry, and subsequently applies a predetermined voltage to the I/O pad. This creates a reverse saturation current through the diode, which is measured by the current measuring device. From this current the user or a computer program determines the temperature of the microprocessor at the diode through the use of a graphical representation of diode reverse saturation current and corresponding temperature.Type: GrantFiled: October 4, 2005Date of Patent: April 14, 2009Assignee: International Business Machines CorporationInventors: David W.
