摘要： Time-correlated photon counting is used to measure integrated circuit (IC) performance related to signal jitter (such as clock jitter) in a manner that is non-invasive to the circuit or node of interest. The signal jitter is measured by counting photon emissions at various nodes of interest across a controlled collapse chip connect (C4) mounted die, without interfering with the normal operation of the circuit of interest. This increases the precision and accuracy of the measurement of signal jitter significantly, since small amounts of phase noise on a particular clock signal edge can be detected. The emitted photons can be detected and subsequently correlated to a precise time base to obtain a statistical spread of switching events in time. The range of the photon distribution can be used to reliably determine safe and reasonable timing guard bands for clock and data paths in an IC.

摘要： A method is provided for manufacturing a die. A supply voltage is provided to a power plane of a selected integrated circuit, formed in and on a semiconductor substrate, having a selected design, so that a respective test current flows through a plurality of test elements, of the selected integrated circuit, each being connected to a respective test point on the power plane, the test points being spaced from one another. A magnitude of each respective test current is detected. A respective test voltage is calculated at each respective test point utilizing the respective magnitude of the respective test current flowing through the respective test element connected to a respective test point. The respective test voltages are utilized to determine at which ones of the test points the respective test voltages are more than a predetermined maximum below a supply voltage. The electric design is altered to an altered electric design if any of the test voltages are below a predetermined minimum below the supply voltage. An integrated circuit having the altered design is then manufactured on another semiconductor substrate.

摘要： A system may include detection of a logical mode of a link port, and changing of a link supply power provided to the link port based on the detected logical mode. Detection of the logical mode may include a determination of whether the link port is terminated by a partner link port. If the link port is not terminated, the link supply power may be reduced to a value that does not preserve logic states of a plurality of link port elements, and, if the link port is terminated, the link supply power may be maintained substantially at Vcc.

摘要： A non-invasive method and apparatus accurately measures the time difference between two signal edges by optically detecting the emission from a ‘beacon device’ that is modulated as a function of time difference. Through the use of this modulation it is possible to perform timing measurement accurately. Embodiments of a voltage modulator circuit modulate timing information into emission intensity. The method and system of the present invention can be used in applications such as clock skew and pulse width measurements.

摘要： Techniques and mechanisms for configuring logic to implement a signal modulation. In an embodiment, the logic includes a finite impulse response (FIR) module comprising circuitry. The selection circuitry may be operable to concurrently receive signals from latch circuitry of the FIR module and, based on the signals, to select an input group of the selection circuitry and to output a voltage identifier. In another embodiment, configuration logic is operable to set an operational mode which determines a total number of concurrent input signals, received by the FIR module, which the FIR module will use to select an input group for generating an output representing a voltage level.

摘要： A driver of a first component and a receiver of a second component of a system are equipped to operate at least one of the driver and the receiver in a low power consumption state, during at least a portion of a quiescent state, when transmitting data from the first to the second component differentially, via a link interface with two lines, coupling the components. The driver and the receiver include respective monitor circuits to detect for the quiescent state, with the driver's monitor circuit monitoring for constancy over a predetermined period, and the receiver's monitor circuit monitoring for zero states on both lines. Further, in one embodiment, the driver's monitor circuit places the driver in the low power consumption state by grounding the two lines.
