  • Debugging simulation of a circuit core using pattern recorder, player and checker
    Patent number: 7979833
    Abstract: Debugging a simulation of a circuit core uses a pattern recorder, a pattern player and a pattern checker to record input stimuli provided to a first core, record output generated by the first core due to the input stimuli, provide the recorded input stimuli to a second core, and determine whether output generated by the second core due to the recorded input stimuli matches the recorded output generated by the first core due to the input stimuli.
    Type: Grant

  • Adaptive data alignment
    Patent number: 7894537
    Abstract: An apparatus including a transmit circuit, a receive circuit, and a control circuit. The control circuit may be configured to present a plurality of transmit data lanes in response to (i) a plurality of transmit data sources and (ii) a plurality of first skew control signals. The receive circuit may be configured to generate a plurality of receive data lanes in response to (i) the plurality of transmit data lanes and (ii) a plurality of second skew control signals. The control circuit may be configured to generate the first skew control signals and the second skew control signals in response to an alignment of the plurality of receive data lanes. The control circuit may adjust a timing of the receive data lanes and the transmit data lanes to achieve arrival of the receive data lanes across a transmission medium within a skew parameter.
