Abstract: A computing system implementing a design characterization tool can sample a distribution of values for manufacturing variation of an integrated circuit described by a circuit design. The design characterization tool can order the samples based on predicted output values of the circuit design set with characteristics in the samples of the values for manufacturing variation. The computing system can implement an analog simulator to simulate the circuit design utilizing a subset of the samples of values for manufacturing variation to identify simulated output values for an output distribution model. The design characterization tool can estimate an error in the order of the samples associated with the predicted outputs of the circuit design based on the simulated output values in the output distribution model. The design characterization tool can modify the output distribution model to correct a bias based on the estimated error in the order of the samples.

Abstract: A computing system implementing a design characterization tool can sample a distribution of values describing manufacturing variation for an integrated circuit described by a circuit design. The design characterization tool can utilize a set of the samples to generate a surrogate model of the circuit design, and can order another set of the samples based on predicted outputs of the surrogate model. The design characterization tool can simulate the surrogate model or the circuit design utilizing the ordered samples, and stop the simulations prior to all of the samples from the distribution having been utilized in the simulations. The design characterization tool can utilize a confidence interval stopping condition or a drought stopping condition to determine when to stop the simulations. The design characterization tool can utilize results of the simulations to characterize operational variation of the circuit design to the manufacturing variation described in the distribution of the values.

Abstract: Techniques of managing heat within an electronic device include providing a vapor chamber as an external surface of an electronic device. For example, when the electronic device includes a thin notebook computer (e.g., an “ultrabook”), the vapor chamber may be, in its entirety or at least a part of, the d-case (i.e., the bottom cover or exterior surface of the laptop, opposite the keyboard and/or trackpad when the notebook computer is open). Such a vapor chamber may be very thin (as thin as 0.3 mm), while being about 50% more stiff and 50× more thermally conductive as aluminum, which may be used as the d-case in conventional notebook computers.

Operation of the at least one fan may draw external air into the housing through the plurality of air intake ports into the user—facing cavity, and into the electronics compartment through the plurality of air channels, for discharge from the housing through the at least one discharge port, to provide cooling of the user-facing cavity and the electronics compartment.

Abstract: Generating spectrally enhanced seismic data expresses seismic data as a convolution of reflectivity and a seismic source wavelet. This seismic source wavelet varies over a sampling interval and defining a total amount of energy over the sampling interval. An enhanced seismic source wavelet that is a single-valued energy spike that yields the total amount of energy over the sampling interval is generated. In addition, the reflectivity is modified to preserve amplitude variation with angle. The reflectivity is convoluted with the enhanced seismic source wavelet and residual energy is added to the convolution to generate the spectrally enhanced seismic data.
