  • Peripheral component interconnect board programmable link training and status state machine and state branching
    Patent number: 12360871
    Abstract: A device may generate a link training and status state machine (LTSSM) test configuration that includes states and paths connecting the states, and may provide the LTSSM test configuration for tracing through by a device under test. The device may receive results associated with tracing through of the LTSSM test configuration by the device under test, and may modify, based on the results, one of the paths of the LTSSM test configuration to include a different one of the states and to generate a modified LTSSM test configuration. The device may provide the modified LTSSM test configuration for tracing through by the device under test.

  • ALIGNING DATA ON PARALLEL TRANSMISSION LINES
    Publication number: 20090063889
    Abstract: The lane skew alignment device of the present invention facilitates the use of the SFI-5 standard interface in an FPGA without the need to rely on feedback signals from a remote device. The delay between lanes is determined using a D-Flip Flop or other type of phase comparator. To minimize the components needed to physically implement the solution a cross-point switch is used to select one of the parallel lanes at a time to be compared to a reference lane, over which the same test signal is transmitted.
