Aspects of the embodiments are directed to systems, methods, and devices, such as an upstream device that includes an input/output port. The input/output port configured to receive a message from an output port of a downstream device; transmit a plurality of acknowledgement messages to the downstream device; and transmit a response message to the received message to the downstream device.

Reducing hardware precision time measurement inaccuracy

Particular embodiments described herein can offer a method for managing power for at least one processor that includes evaluating a plurality of ports associated with an electronic device; determining that a particular pin associated with at least one of the ports is not receiving a signal; disabling a squelch function associated with the electronic device; and gating power associated with a physical layer (PHY) of the electronic device.

System and method for power management

Various embodiments are generally directed to an apparatus, method and other techniques for determining when a communications port is in a first low power state, determining that a coupled device entered a low power state and enabling a second low power state based on the determination that the device has entered the low power state, the second low power state to use less power than the first low power state.

Techniques enabling low power states for a communications port

Particular embodiments described herein can offer a method that includes powering down a root port; initiating a first downstream cycle by a central processing unit (CPU) to the root port; identifying a power up activity for the CPU; and triggering an exit flow for a power state in conjunction with sending a second downstream cycle to the root port. In more particular embodiments, the triggering of the exit flow for the power state and the sending of the second downstream cycle to the root port occurs in a substantially parallel fashion. In addition, a prewake indicator can be sent to the root port to trigger the exit flow before the CPU is powered up and the second downstream cycle is sent.

Processor hiding its power-up latency with activation of a root port and quickly sending a downstream cycle

An apparatus and method for automatically testing circuit boards, such as computer system boards and the like. The circuit board device under test (DUT) is loaded into an automated test apparatus (tester), which includes a mechanism for automatically connecting test electronics to various DUT circuitry and I/O ports via corresponding connectors on the DUT. A type of DUT is identified, and a corresponding set of tests are performed to verify the operation of the DUT. Appropriate power signals and sequencing are also applied to the DUT, as defined by it type. Data logging is performed to log the results of the testing. The apparatus includes replaceable probe/connector plates that are DUT-type specific and corresponding universal electronics and cabling to enable a variety of different board types to be tested with the same apparatus.

Universal automated circuit board tester

A USB (universal serial bus) controllable power supply and method for supplying power to a circuit board device under test (DUT) via a controllable power supply. The power supply employs a USB interface to communicate with external devices, such as a host computer. In response to power supply control commands from the host computer, the controllable power supply provides various power outputs at various external connectors, including main power, ATX12V power, and peripheral power to be used for peripheral devices corresponding to a DUT test apparatus. The controllable power supply also provides a built-in short circuit check function, and monitors the voltage levels of its power outputs to ensure they are within predefined limits. The power supply also supports emergency shutdown operations, and provides an EOS (emergency overstress) function. In one embodiment, the power supply includes an integrated USB hub.
