  • Patent number: 11475199
    Abstract: Simulating a circuit design using a data processing system includes partitioning the circuit design into a top-level design and a sub-design along a boundary defined by one or more stream channels coupling a component of the top-level design with the sub-design. The sub-design is extracted from the circuit design and replaced with a stub having a client socket. A wrapper having a server socket is added to the sub-design. The top-level design and the sub-design are compiled into respective simulation kernels. The circuit design is simulated by executing the respective simulation kernels concurrently. The respective kernels communicate over a socket connection established by the client socket and the server socket. In other aspects, the partitioning results in partitions such that one partition is simulated as software and another partition is implemented in circuitry such that the circuit design may be hardware co-simulated.

  • Publication number: 20220247866
    Abstract: Voicemail spam detection is performed based on content of voicemail messages. The content of an incoming voicemail message is compared to a spam template that includes a representation of a spam voicemail. Spam templates may be generated based on spam indications provided by users for voicemail messages they have received. User indications for sufficiently similar voicemail messages may be aggregated by maintaining a vote count for a spam template that reflects how many times a user has indicated a matching voicemail message is spam. A spam template may also include an occurrence count that reflects how many times voicemail messages matching a spam template have been detected in a telephony system. An incoming voicemail message may be compared to spam templates and, responsive to a match of content and/or a corresponding vote count or occurrence count meeting a condition, the voicemail message may be identified as spam.

  • Patent number: 10726182
    Abstract: Disclosed approaches involve simulating a circuit design specified in a hardware description language (HDL). During simulation, a thread is started at an edge of a simulation clock signal for evaluation of states of a finite state machine (FSM) that represent a series of events specified in a statement in the HDL. The thread transitions from one state to a next state in the FSM in response to evaluation of the one state. In response to encountering a fork state in the FSM, the thread is forked into two threads during simulation. The fork state represents a composite operator in the statement, and the FSM has a branch from the fork state for each operand of the composite operator. In response to encountering a join state in the FSM by the two threads, the two threads are joined into one thread.
