摘要： The present invention provides a method to implement prognostics and health management (PHM) in individual electronic products (such as parts, components, boards, assemblies, devices, systems, and systems of systems). The PHM algorithm is performed during product screening tests, diagnostic processes, or after the manufacturer process. Certain performance, signal values and parameters, environmental and operational loads, or their correlations are recorded, extracted, and stored in electronic memory for that particular product. The stored data represents a the healthy baseline reference of that particular product at the initial point of its life. In one embodiment, where the healthy baseline is stored in the product, it can be updated according to different usage conditions. In one embodiment with the data is stored within the product, the PHM analysis can be performed in the field under conditions of use. In another embodiment the healthy baseline can be stored elsewhere and the product returned to the company storing the healthy baseline data, for PHM analysis.

摘要： Clock phases of clock signals in a dual clock tree are adjusted to compensate for variances in propagation delays of buffers in the clock tree. A first input clock and a second input clock are generated with the second input clock having a phase that is programmably shifted relative to the first input clock when the system is operating at a lowered operating voltage or different temperature, for example. The first and second input clocks are coupled to a dually clocked flip flop, each having a primary latch and a secondary latch. A composite clock signal is generated in response to the first input clock and the second input clock. For example, a first signal is latched in the primary latch in response to the composite clock signal and a second signal is latched in the secondary latch in response to the first input clock signal.

摘要： A contour measurement system determines three dimensional surface information of an object using a projection moiré technique to obtain a single fringe pattern that is analyzed using a phase-shift image processing method. A grating is projected onto the object and the reflected fringe pattern is recorded by a camera and stored digitally as an array of pixels. An estimated fringe spacing is then determined for each pixel. Using the estimated fringe spacings, four phase-shifted fringe patterns are generated by correlation integration and then used in a phase calculation to obtain wrapped phase information for the object. This phase information is then unwrapped and normalized, producing a set of data points representative of the unwrapped phase information. Noise suppression using pattern reconstruction and smoothing can be utilized at this point to improve the signal to noise ratio. Thereafter, updated estimated spacings are determined for each data point using a curve fitting function such as a localized least squares fit. The system then performs one or more additional iterations of the correlation integration, phase calculation, unwrapping, noise suppression, and fringe spacing update steps, each time using the newest updated estimated spacing in the correlation integration. After the final iteration, the unwrapped phase information is demodulated and used to calculate the three dimensional coordinates of points on the object surface. A fractional pixel analysis technique is also disclosed for use in the correlation integration and updated estimated spacing calculations.

摘要： A method is described for simulating the f-sigma timing path delay of an integrated circuit design when local transistor variations determine the stochastic delay. This is achieved by determining an estimated delay time for a first timing path using non-linear operating point analysis of local variations (NLOPALV). An operating point is calculated for each cell that is included in a timing path in the integrated circuit design. The f-sigma operating point of a cell-arc is a point on the cell-arc delay function (CADF). An f-sigma delay value is determined for each cell using the selected operating point on the CADF of the cell. The determined delay values of the plurality of cells in the timing path may then be combined to predict the estimated delay for the entire timing path. The method may be extended to deal with slew rate, predict hold time statistics, prune paths, and deal with convergent paths.
