Abstract: An apparatus includes a crossbar circuit that routes one or more packets between one or more ingress domains and one or more egress domains. The crossbar circuit includes sub-crossbar domains. An ingress control circuit associated with the one or more ingress domains may distribute packet data of the one or more packets to the sub-crossbar domains. An egress control circuit of the apparatus receives data bits associated with the packet data from egresses associated with the plurality of sub-crossbar domains. The egress control circuit may reorder or refrain from reordering the data bits based on an attribute associated with the distribution of the packet data.

Abstract: An apparatus includes operational circuitry and Hardware Diagnostics Circuitry (HDC). The HDC is configured to receive a definition of multiple trigger rules, each trigger rule specifying a respective trigger event as a function of trigger data sources in the operational circuitry, to receive a definition of (i) a pre-trigger logging set selected from among a plurality of diagnostics data sources in the operational circuitry, and (ii) for each trigger rule, a respective post-trigger logging set including a set of one or more of the diagnostics data sources, and, during operation of the operational circuitry, to log the diagnostics data sources in the pre-trigger logging set, to log the trigger data sources and to repeatedly evaluate the trigger rules, and, in response to triggering of a given trigger event by a given trigger rule, to start logging the diagnostics data sources in the post-trigger logging set of the given trigger rule.

Abstract: A system includes one or more processors to trace one or more packets transmitted by an application distributed among a plurality of computing nodes. The one or more processors are to generate tracing data based at least in part on tracing the one or more packets. The tracing data includes temporal information associated with transmission of the one or more packets. The one or more processors are to manage a data allocation associated with the application based on the tracing data.

Abstract: A method for circuit design automation includes appending a non-synthesizable input having a unique identifier to HDL code that specifies a physical input of the circuit. For the physical components in the circuit to which a signal from the physical input is to propagate, corresponding non-synthesizable components are appended, having respective identifiers assigned responsively to the unique identifier of the non-synthesizable input, to the HDL code that specifies the physical components. The design is verified by simulating operation of the circuit using the HDL code, including both the physical and non-synthesizable inputs and components. After verifying the design, a netlist synthesis tool automatically generates a netlist of the circuit including the physical inputs and components while omitting the non-synthesizable inputs and components.

Abstract: A method for communication, includes routing unicast data packets among nodes in a network using respective Layer-3 addresses that are uniquely assigned to each of the nodes. Respective Layer-2 unicast addresses are assigned to the nodes in accordance with an algorithmic mapping of the respective Layer-3 addresses. The unicast data packets are forwarded within subnets of the network using the assigned Layer-2 addresses.
