Abstract: A method (50, 70, 600) provides thermal protection for an IC device that has multiple components. For each component, temperatures are sensed (51), each of which associated with a different area of the respective component and a respective temperature sense signal is output indicative of the highest sensed temperature of the respective component. For each of the components, the respective temperature sense output signal is sampled (52) to produce a sequence of discrete sampled temperature values. A sequence of differences between a reference temperature value and each of the discrete sample temperatures is integrated (53) over time to compute, for each of the components, a respective integration output. The respective integration output computed for each of the switches is compared (54) to a threshold value. An action related to the thermal protection function is initiated (55) upon the integration output of an affected component exceeding the threshold value.

Abstract: A network switch and associated method of operation for establishing a low latency transmission path through the network which bypasses the packet queue and scheduler of the switch fabric. The network switch transmits each of a plurality of data packets to the identified destination egress port over the low latency transmission if the data packet is identified to be transmitted over the low latency transmission path from the ingress port to the destination egress port, and transmits the data packet to the destination egress port through the packet queue and scheduler if the data packet is not identified to be transmitted over the low latency transmission path from the ingress port to the destination egress ports.

Abstract: A method for integrated circuit design with delay verification includes storing configuration files for a slew-rate Machine Learning (ML) model, a net-delay ML model and a cell-delay ML model. A user design is received, slew-rate feature values, net-delay feature values and cell-delay feature values are extracted from the user design, the configuration files are loaded to form inference cores, and operations of the slew-rate inference core are performed to calculate predicted slew-rate values that are sent to ML design tools. Operations of the net-delay inference core are performed to calculate predicted net-delay values that are sent to the ML design tools. Operations of the cell-delay inference core are performed to generate predicted cell-delay values that are sent to the ML design tools. The user design is iterated until a user design is obtained that is free of timing violations.

Abstract: A method and apparatus for reading a flash memory device are disclosed. A Regression Neural Network (RNN) inference model is stored on a flash controller. The RNN inference model is configured for identifying at least one Threshold-Voltage-Shift Read-Error (TVS-RE) curve that identifies a number of errors as a function of Threshold Voltage Shift Offset (TVSO) values. The operation of a flash memory device is monitored to identify usage characteristic values. A neural network operation of the RNN inference model is performed to generate a TVS-RE curve corresponding to the usage characteristic values. The input for the neural network operation includes the usage characteristic values. A TVSO value is identified corresponding to a minimum value of the TVS-RE curve. A read of the flash memory device is performed using a threshold-voltage-shift read at the TVSO value.

Abstract: A method for fabricating a silicon carbide semiconductor device includes providing a SiC epitaxial layer disposed over a surface of a SiC substrate, forming an implant aperture in a hardmask layer on a surface of the expitaxial SiC layer, implanting contact and well regions in the SiC epitaxial layer through the hardmask layer, the contact region lying completely within and recessed from edges of the well region by performing one of implanting the well region through the implant aperture, reducing the area of the implant aperture forming a reduced-area contact implant aperture and implanting the contact region through the reduced-area implant aperture to form a contact region, and implanting the contact region through the implant aperture, increasing the area of the implant aperture to form a increased-area well implant aperture and implanting the well region through the increased-area implant aperture to form a well region completely surrounding the contact region.

Abstract: A system and method for data sampler drift compensation in a SerDes receiver. Off-data values are received at a drift compensation engine from a plurality of data value selectors coupled to one of a plurality of data sampler pairs of a speculative Decision Feedback Equalizer (DFE) of a SerDes receiver. A drift compensation value for each of the data samplers is generated by the drift compensation engine based upon the off-data values received from each of the plurality of data value selectors and, a sampling level of each of the data samplers of the plurality of data sampler pairs of the DFE is adjusted based upon the drift compensation value from the drift compensation engine.
