  • Patent number: 10282326
    Abstract: An integrated circuit is provided for obtaining interrupt performance metrics. The integrated circuit includes a microprocessor executing an interrupt service routing monitoring framework that includes an interrupt handler and an application programming interface. The interrupt handler executes in response to a trigger condition and obtains timing data that includes at least one sample of a value of a timing logic according to a sampling schedule. The API exposes interrupt configuration functionality for registering the interrupt handler with a supervisory program and for configuring the interrupt handler to obtain the timing data.

  • Patent number: 9983971
    Abstract: Techniques for efficient benchmarking. One method includes obtaining convergent results by performing a benchmarking test with a particular length to obtain a result (time), scaling the time exponentially, performing additional benchmarking tests, obtaining results for those tests, and determining whether the results scale linearly with length. Another method includes obtaining variance for non-convergent results by performing multiple sequences of benchmarking test. Within each new sequence performed, the benchmarking tests are spaced out further apart in time. If new maximum or minimum results are obtained, then further test sequences are performed and if no new maximum or minimum results are obtained after a threshold number of sequences, then the test ends. A device and computer-readable medium for performing benchmarking are also provided herein.

  • Patent number: 9678150
    Abstract: Various example implementations are directed to circuits and methods for debugging circuit designs. According to an example implementation, waveform data is captured, for a set of signals produced by a circuit design during operation. Data structures are generated for the set of signals and waveform data for the signals is stored in the data structures. Communication channels associated with the set of signals are identified. Waveform data stored in the data structures is analyzed to locate transaction-level events in the set of signal for one or more communication channels. Data indicating locations of the set of transaction-level events is output by the computer system.

  • Patent number: 9626780
    Abstract: Visualizing transactions in a transaction-based system includes displaying, on a display device, an x-y coordinate system including an x-axis and a y-axis, wherein the x-axis is demarcated in units of time and the y-axis is demarcated according to a transaction characteristic and formatting, using a processor, each of a plurality of transactions of a transaction system as a line having a start end representing a start of the transaction and a terminating end representing an end of the transaction. For each line representing a transaction, the start end of the line is located at a first x-coordinate corresponding to a start time of the transaction and a first y-coordinate of zero. For each line, the terminating end of the line is located at a second x-coordinate corresponding to an end time of the transaction and a second non-zero y-coordinate that is the same for each line. Each line is displayed on the display device using the processor in combination with the x-y coordinate system.

  • Patent number: 9581643
    Abstract: Methods and circuits are disclosed for testing a partial circuit design including circuit modules having a set of ports configured to be driven by signals from ports of one or more circuits omitted from the partial circuit. The set of ports are identified by identifying ports that are not connected by a net to another port or input/output (I/O) pin in the circuit design and that form inputs to slave circuits in the circuit modules. A traffic generator circuit is added to the partial design to form a test circuit design. The traffic generator circuit is configured to provide to the set of ports respective input data signals having a pattern consistent with master-to-slave communication. Operation of a test circuit design is modeled. A set of data signals generated by the circuit modules during the modeled operation of the test circuit design is captured and stored.
