  • Patent number: 11681843
    Abstract: Various aspects of the disclosed technology relate to machine learning-based chain diagnosis. Faults are injected into scan chains in a circuit design. Simulations are performed on the fault-injected circuit design to determine test response patterns in response to the test patterns which are captured by the scan chains. Observed failing bit patterns are determined by comparing the unloaded test response patterns with corresponding good-machine test response patterns. Bit-reduction is performed on the observed failing bit patterns to construct training samples. Using the training samples, machine-learning models for faulty scan cell identification are trained. The bit reduction comprises pattern-based bit compression for good scan chains or cycle-based bit compression for the good scan chains. The bit reduction may further comprise bit-filtering. The bit-filtering may comprises keeping only sensitive bits on faulty scan chains for the training samples construction.

  • Patent number: 11669667
    Abstract: Systems and methods for automatic test pattern generation (ATPG) for parametric faults are described. A model may be constructed to predict a measurement margin for an integrated circuit (IC) design based on a random sample of random variables. A set of failure events may be determined for the IC design using the model, where each failure event may correspond to a set of values of the random variables that is expected to cause a metric for the IC design to violate a threshold.

  • Patent number: 11663814
    Abstract: The present disclosure advantageously provides a system and a method for skipping recurrent neural network (RNN) state updates using a skip predictor. Sequential input data are received and divided into sequences of input data values, each input data value being associated with a different time step for a pre-trained RNN model. At each time step, the hidden state vector for a prior time step is received from the pre-trained RNN model, and a determination, based on the input data value and the hidden state vector for at least one prior time step, is made whether to provide or not provide the input data value associated with the time step to the pre-trained RNN model for processing. When the input data value is not provided, the pre-trained RNN model does not update its hidden state vector. Importantly, the skip predictor is trained without retraining the pre-trained RNN model.

  • Patent number: 11605015
    Abstract: A hybrid quantum-classical (HQC) computer prepares a quantum Boltzmann machine (QBM) in a pure state. The state is evolved in time according to a chaotic, tunable quantum Hamiltonian. The pure state locally approximates a (potentially highly correlated) quantum thermal state at a known temperature. With the chaotic quantum Hamiltonian, a quantum quench can be performed to locally sample observables in quantum thermal states. With the samples, an inverse temperature of the QBM can be approximated, as needed for determining the correct sign and magnitude of the gradient of a loss function of the QBM.

  • Patent number: 11574103
    Abstract: Aspects of the invention provide means for addressing layout retargeting shortfalls. Initially, an original design shape in the layout is allowed to be simulated by process simulation to form process simulation contours. A polygon is then fitted to the process simulation contours to form a fitted simulated shape. Subsequently, whether the fitted simulated shape differs from the original design shape is detected. The process simulation may reflect the changes to the layout that occur at a foundry as part of a retargeting process. Advantageously, addressing a layout for retargeting shortfalls in accordance with aspects of the invention is likely to result in manufactured semiconductor devices having higher yields and reliability than those produced from a like layout that is not addressed in this manner.

  • Patent number: 11556052
    Abstract: A lithography process is described by a design for a lithographic mask and a description of the lithography configuration, which may include the lithography source, collection/illumination optics, projection optics, resist, and/or subsequent fabrication steps. The actual lithography process uses a lithographic mask fabricated from the mask design, which may be different than the nominal mask design. A mask fabrication model models the process for fabricating the lithographic mask from the mask design. Typically, this is an electron-beam (e-beam) process, which includes e-beam exposure of resist on a mask blank, processing of the exposed resist to form patterned resist, and etching of the mask blank with the patterned resist. The mask fabrication model, usually in conjunction with other process models, is used to estimate a result of the lithography process. Mask correction is then applied to the mask design based on the simulation result.
