  • Patent number: 9009644
    Abstract: A layout system automatically generates via definitions for a routing tool based on manufacturability of vias based on the via definitions. A physical verification tool of the system applies a set of preliminary via definitions to an integrated circuit test design at each of a plurality of offsets from a plurality of via locations to generate a set of candidate via definitions. Candidate via definitions that violate one or more design rules are discarded. A hierarchy constructor tool ranks the resulting candidate via definitions based on a combination of their manufacturability and frequency of applicability in the test design, and a predefined number of the candidate via definitions are selected based on their ranking. These selected via definitions can be used by a routing tool to generate a layout for another (non-test) integrated circuit device.

  • Publication number: 20150098160
    Abstract: A protection circuit and a gate driving circuitry. The protection circuit is for protecting a p-type back-to-back MOS switch. The circuit receives an input driving signal and provides a driving output signal to common gates of the p-type back-to-back MOS switch. The circuit comprises a driving signal insulation switch for disconnecting the common gate of the p-type back-to-back MOS switch from the received input driving signal when the voltage of the common gates is larger than the supply voltage of the circuit. The circuit further comprises a gate source coupling switch for coupling a voltage received at the common source of the p-type back-to-back MOS switch to the common gate if a received voltage at the common sources is larger than a reference voltage Vref.

  • Publication number: 20150097623
    Abstract: A device includes an amplifier having a first path and a second path and a first variable attenuator connected to the first path. The device includes a controller coupled to the first variable attenuator. The controller is configured to determine a magnitude of an input signal to the amplifier. When the magnitude of the input signal is below a threshold, the controller is configured to set an attenuation of the first variable attenuator to a first attenuation value. When the magnitude of the input signal is above the threshold, the controller is configured to set the attenuation of the first variable attenuator to a second attenuation value. The second attenuation value is less than the first attenuation value.

  • Publication number: 20150097557
    Abstract: The embodiments described herein can provide a variable reluctance sensor (VRS) interface that may reduce the probability of erroneous transitions in a resulting generated detect signal. As such, the VRS interface can improve the accuracy of position and/or motion determinations, and thus can improve the performance of a wide variety of devices that use variable reluctance sensors. To facilitate this, the VRS interface includes a pre-processing circuit configured to modify a VRS signal to prevent the modified VRS signal from dropping below a threshold value and generating erroneous transitions in the detect signal pulse between leading and lagging edges of a tooth. In one embodiment the pre-processing circuit comprises a peak and hold circuit. In another embodiment the pre-processing circuit comprises a resistor-capacitor circuit. In either case the pre-processing circuit can prevent erroneous transitions in the detect signal and thus may improve the performance and accuracy of the system.

  • Publication number: 20150097556
    Abstract: The embodiments described herein include systems with a variable reluctance sensor (VRS) interface and methods of their operation that may reduce the probability of erroneous transitions in a resulting generated detect signal. As such, the VRS interface can improve the accuracy of position and/or motion determinations, and thus can improve the performance of a wide variety of devices that use variable reluctance sensors. In one embodiment the VRS interface uses a comparator with hysteresis to generate a trailing edge signal. In another embodiment the VRS interface uses bias voltages to reduce the probability of erroneous transitions in a trailing edge signal. In either case the VRS interface can prevent erroneous transitions in the detect signal and thus may improve the performance and accuracy of the system.

  • Patent number: 9000589
    Abstract: A surface mount semiconductor device is assembled by positioning an array of semiconductor dies with an array of metallic ground plane members between and beside the semiconductor dies. The arrays of dies and ground plane members are encapsulated in a molding compound. A redistribution layer is formed on the arrays of dies and ground plane members. The redistribution layer has an array of sets of redistribution conductors within a layer of insulating material. The redistribution conductors interconnect electrical contacts of the dies with external electrical contact elements of the device. As multiple devices are formed at the same time, adjacent devices are separated (singulated) by cutting along saw streets between the dies. The molding compound is interposed between tie bars of the ground plane members and the insulating material of the redistribution layer in the saw streets, and at the side surfaces of the singulated devices.

  • Patent number: 9000507
    Abstract: A mechanism is provided for extending useable lifetimes of semiconductor devices that are subject to trapped charge carriers in a gate dielectric. Embodiments of the present invention provide heat to the gate dielectric region from one or more sources, where the heat sources are included in a package along with the semiconductor device. It has been determined that heat, when applied during a period when the channel region of a transistor is in accumulation mode or is not providing a current across the channel, can at least partially recover the device from trapped charge carrier effects. Embodiments of the present invention supply heat to the affected gate dielectric region using mechanisms available where the semiconductor device is used (e.g., in the field).

  • Patent number: 9002694
    Abstract: An approach is provided in which a power design verification system retrieves a power intent data corresponding to a power design, which identifies the power design's power modes and power mode transition conditions. The power design verification system selects one of the power mode transition conditions, which identifies input signals that invoke a transition from a first power mode to a second power mode. In turn, the power design verification system generates simulation stimuli based upon the identified input signals and simulates the power design utilizing the generated simulation stimuli accordingly.
