Abstract: A high-speed signal subsystem testing system includes a processing system having a transmitter and a receiver, a loop back subsystem coupled to the transmitter and receiver to provide a testing communication path between the transmitter and the receiver, and a communication path testing engine coupled to the transmitter and the receiver. The communication path testing engine generates test signal(s) and transmits the test signal(s) via the transmitter and through the testing communication path provided by the loop back subsystem and, in response, receives test signal result(s) via the receiver and through the testing communication path provided by the loop back subsystem, The communication path testing engine processes the test signal result(s) to generate a testing impedance profile for the testing communication path, and compares the testing impedance profile to an expected impedance profile to determine whether a testing communication path issue exists in the testing communication path.

Abstract: A high-speed signal subsystem testing system tests a processor transmitter and receiver coupled to a connector via a transmitter trace and a receiver trace, respectively. A transmitter test circuit on a testing board coupled to the connector compares a transmitter voltage received from the transmitter via the transmitter trace and the connector to a common mode voltage range and, in response to the transmitter voltage being outside the common mode voltage range, provides a transmitter trace issue signal. A receiver test circuit on the testing board coupled to the connector transmits a first test voltage towards the receiver, compares a second test voltage detected at the receiver test circuit in response to transmitting the first test voltage towards the receiver to a reference test voltage and, in response to the second test voltage being above the reference test voltage, provides a receiver trace issue signal.

Abstract: An information handling system includes a memory subsystem and a basic/input out system (BIOS). The BIOS performs multiple trainings of the memory subsystem, and each of the trainings is performed at a different temperature. The BIOS stores multiple derating values in a derating table of the BIOS, and each of the derating values corresponds to a respective tap value at a respective temperature. During a subsequent power on self test of the information handling system, the BIOS performs a first training of the memory subsystem, and stores a first set of tap values. During a runtime of the information handling system, a memory controller determines whether a temperature of the information handling system has changed by a predetermined amount. In response to the temperature changing by the predetermined amount, the memory controller utilizes the derating values in the derating table to automatically update the tap values.
