Abstract: An apparatus may comprise a skew detection circuit to sample a common mode voltage of a differential signal, wherein the sampled common mode voltage is indicative of an amount of skew between a first signal of the differential signal and a second signal of the differential signal; and a skew compensation circuit to adjust a delay of the first signal or the second signal based on the sampled common mode voltage to reduce the amount of skew.

Abstract: A die with a transmission circuit, a reception circuit, and a comparison circuit can be provided. The transmission circuit can be configured to transmit a first signal through a first channel at a first transmission rate and a first transmission amplitude. The reception circuit can be in communication with the transmission circuit through the first channel. The reception circuit can receive a second signal at a first reception rate and at a first reception amplitude. The comparison circuit can be in communication with the transmission circuit and the reception circuit. The comparison circuit can be configured to: determine a first rate error value, determine a first amplitude error value, compare the first rate error value with a rate threshold to determine a first rate error occurrence, and compare the first amplitude error value with an amplitude threshold to determine a first amplitude error occurrence.

Abstract: Apparatuses, systems and methods associated with integrated circuit packages with integrated test circuitry for testing of a channel between dies are disclosed herein. In embodiments, an integrated circuit (IC) package may include a first die, a second die, and a channel that couples the first die to the second die. The first die may include a transmitter, test circuitry coupled between the transmitter and the channel, wherein the test circuitry is to control charge and discharge of the channel, and a receiver coupled to the channel. The receiver may determine a voltage of the channel during charge and discharge of the channel, and output an indication of the voltage. Other embodiments may be described and/or claimed.

Abstract: Disclosed herein are systems and methods for the characterization of transmission media, among other embodiments. For example, a system for characterizing a transmission medium may include: a waveform generator to generate an initial input waveform; waveform pre-processing circuitry to process the initial waveform to generate a processed input waveform for provision to the transmission medium, wherein the processed input waveform has a maximum amplitude greater than a maximum amplitude of the initial input waveform; and waveform output circuitry to display or store data representative of an initial output waveform, wherein the initial output waveform is output from the transmission medium as a reflection or transmission of the processed input waveform.

Abstract: A package substrate may include a circuit and a leaky surface wave launcher. The circuit may perform engineering tests and end-user operations using sideband signals. The leaky surface wave launcher may perform near field wireless communication. The leaky surface wave launcher may include a via and a strip line. The via may be electrically coupled to the circuit. The via may provide the sideband signals to and receive the sideband signals from the circuit. The strip line may be electrically coupled to the via. The strip line may be excited by the sideband signals to wirelessly couple the leaky surface wave launcher with an external device. The strip line and the via may be unbalanced such that the strip line generates a leaky wave that propagates at least a portion of the package substrate and an environment proximate the package substrate.
