  • Patent number: 11041907
    Abstract: The present invention facilitates efficient and effective device testing and debugging. In one embodiment, a tester system includes: a controller processor, a plurality of programmable accelerator circuits, and a plurality of load boards respectively. The plurality of programmable accelerator circuits providing input test signals and capture output test signals. The plurality of load boards apply the input test signals to a plurality of devices under test (DUTs) and capture the output test signals therefrom. In one exemplary implementation, each of the plurality of load boards includes a first set of connections that transmit input test signals to a respective DUT, a second set of connections that receive output test signals from the respective DUT, and sideband connectors. The sideband connectors receive test related information from the DUT.
