  • Patent number: 11960811
    Abstract: New techniques for the partitioning of big element blocks in a circuit are disclosed. The techniques partition both pre-layout and post-layout circuits. If a post-layout circuit has different simulation results from a pre-layout circuit, the techniques determine where and how “cross-talk” of the RC networks due to RC extraction is changing the circuit physics behavior from the original design of the circuit. A flow of the local circuit simulation of the pre-layout netlist and the post-layout netlist of the same design is presented. A flow of reference or relative or differential circuit simulation of a known design and a new design of the same kind is described. This Abstract is not intended to limit the scope of the claims.

  • Patent number: 11947480
    Abstract: A communication device includes controller circuitry and transmitter circuitry. The controller circuitry determines a number of strings of consecutive ones in a data packet, and determines a number of stuffed bytes based on the number of strings of consecutive ones. Further, the controller circuitry schedules a transaction packet to be transmitted within a bus interval based on a determination that a total number of bytes of the transaction packet is less than a number of available bytes in the bus interval. The total number of bytes of the transaction packet is based on a number of payload bytes of the data packet and the number of stuffed bytes. The transmitter circuitry transmits the transaction packet during the bus interval based on the controller circuitry scheduling the transaction packet for transmission.

  • Patent number: 11941339
    Abstract: Described is technology for automatically generating a routing for an integrated circuit (IC) design. Information describing pin-pairs of an integrated circuit (IC) design is received. An initial routing of the IC design is determined by (i) defining connected wires between each pin-pair in the set of pin-pairs, and (ii) evaluating a target resistance for the pin-pair over the connected wires, wherein each connected wire is routed with other connected wires. A resistance adjustment is applied to adjust wire resistance of the connected wires of the initial routing. The resistance adjustment can be based on a square routing in response to a wire resistance being below the target resistance; or the resistance adjustment can be based on a multi-layer stacking in response to the wire resistance being above the target resistance. The routing is provided in patterns as generated by the initial routing and the resistance adjustment.

  • Patent number: 11941379
    Abstract: A system performs static program analysis with artifact reuse. The system identifies artifacts associated with the software program being analyzed. The system processes the identified artifacts for performing static program analysis and transmits either the artifacts or identifiers for the artifacts to a second processing device for performing program analysis. The second processing device receives the artifacts and uses the received identifiers to retrieve the artifacts from a networked storage system. The second device also retrieves stored summaries of previous program analysis from the networked storage system. The program analysis uses the retrieved artifacts to generate work units for static program analysis. The analysis is performed only for those work units that are determined to remain unchanged from previous static program analysis cycles.

  • Patent number: 11921160
    Abstract: Sensor data relating to operating conditions for an integrated circuit are read out through scan chains. Scan tests are run on an integrated circuit containing logic circuits that implement logic functions. The logic circuits are interconnected to form scan chains which are used in running the scan tests. The scan test data resulting from the scan tests is read out from the logic circuits through these scan chains. During the scan tests, sensor blocks capture measurements of the operating conditions for the logic circuits. The operating conditions may include process, voltage and/or temperature conditions, for example. The sensor blocks are also interconnected to form one or more scan chains, and sensor data produced from the captured measurements is read out through these scan chains concurrently with the read out of the scan test data.
