  • Publication number: 20240194645
    Abstract: An integrated circuit (IC) device includes a block of integrated circuitry that includes functional circuitry and configurable interface circuitry. The configurable interface circuitry includes output circuitry that routes a node of the functional circuitry to an output node of the block, and input circuitry that selectively routes the output node of the block or an input node of the block to the functional circuitry. The output circuitry may route a selectable subset of multiple nodes of the functional circuitry to respective output nodes of the block, and the input circuitry may be configured to route the output nodes of the block back to the functional circuitry in the absence of an adjacent block (e.g., to repurpose the output circuitry), or in addition to interfacing with the adjacent block.

  • Patent number: 11405776
    Abstract: A method for troubleshooting and resolving access point device uplink failures. The method includes detecting an unresponsive access point on a wired computer network. In addition, the method includes retrieving a record of peer access points to determine the peer access points for the unresponsive access point. Further, the method proceeds to sending a first request to a peer access point of the unresponsive access point to query the unresponsive access point for a response over a wireless network. In response to the query, the network management system sends a notification that the unresponsive access point has a cable malfunction if the unresponsive access point responds to the query. Furthermore, the method includes, in response to the query, sending a notification to the network management system to inform that the unresponsive access point has a power malfunction if the unresponsive access point fails to respond to the query.

  • Patent number: 11374564
    Abstract: Examples of the present disclosure provide power gating for stacked die structures. In some examples, a stacked die structure comprises a first die and a second die bonded to the first die. In some examples, a power gated power path is from a bonding interface between the dies through TSVs in the second die, a power gating device in the second die, and routing of metallization layers in the second die to the circuit region in the second die. In some examples, a power gated power path comprises a power gating device in a power gating region of the first die and is configured to interrupt a flow of current through the power gated power path to a circuit region in the second die.

  • Publication number: 20210160885
    Abstract: Systems and methods are provided for seamless and automatic upgrade of access points in a facility with minimal disruption, particularly, for important users of a network. The access points may be ranked, and the rankings may be aggregated to identify a sub-region of the facility with the lowest ranked access points. Various sub-sets of the access points in the identified sub-region can be updated separately so that spatial coverage by the other sub-sets maintains continuous access within the sub-region during the updates. Updates to later sub-sets and/or sub-regions can be performed contingent on the success of the earlier updates. In this way, updates can be verified on access points used by lower-priority users such as guest users of the network to avoid disruption of access to more important users such as executives or safety workers on the network.

  • Patent number: 11017822
    Abstract: Examples described herein provide a method for disabling a defective portion of a fabric die of a stacked IC device. The method includes receiving a signal indicating that a portion of a fabric die of a stacked IC device including at least two fabric dies is defective. The method further includes, in response to the signal, pulling a source voltage rail of the defective portion to ground, thereby disabling the portion, and operating the remainder of the fabric die without interference from or contention with the disabled portion. In one example, the stacked IC device is an active on active (AoA) device, and the portion of the fabric die includes a configuration memory cell. In one example, the signal is received after power-up of the stacked IC device.

  • Patent number: 11004833
    Abstract: Examples described herein generally relate to multi-chip devices having stacked chips. In an example, a multi-chip device includes a chip stack that includes chips. Neighboring chips are connected to each other. Plural chips of the chips collectively include columns of broken via pillars and bridges. Each of the plural chips has a broken via pillar in each column. The broken via pillar has first and second continuous via pillar portions aligned in a direction normal to a side of a semiconductor substrate of the respective chip. The first continuous via pillar portion is not connected within the broken via pillar to the second continuous via pillar portion. Each of the plural chips has one or more of the bridges. Each bridge connects, within the respective chip, the first continuous via pillar portion in a column and the second continuous via pillar portion in another column.

  • Patent number: 10990555
    Abstract: Embodiments herein describe an interface between PL fabric and a hardened block that includes a programmable pipeline. This pipeline includes at least a sequential element and a bypass path. For time critical nets in a netlist, the programmable IC routes a net through the sequential element. Doing so mitigates or eliminates the uncertainty associated with routing the net from the hardened block through PL fabric. Also, the sequential element can increase the available time for capturing the data. For less time critical nets, the net can route through the bypass path. This means the route from the hardened block to the PL fabric is determined on the fly by a routing algorithm rather than being fixed.
