Methods, apparatuses and systems for physical link error data capture and analysis. A receiver is coupled to receive a data stream via a point-to-point serial link. A control circuit is coupled with the receiver to cause the receiver to selectively sample the data stream according to an offset parameter and an interval parameter. Comparison circuitry compares the data stream sample to expected data values to determine a bit error rate.

Apparatuses, systems and methods for detecting errors in data streams on point-to-point serial links

Methods, apparatuses and systems for physical link error data capture and analysis.

Error monitoring for serial links

A condition is detected to cause a component having physical layer circuitry with a transmitter and a receiver to enter a testing state. The transmitter transmits a pre-selected data pattern while comparing data received by the receiver to the pre-selected data pattern during a first phase of the testing state. The transmitter transmits data received by the receiver without comparing the data received by the receiver to the pre-selected data pattern during a second phase of the testing state.

Compliance of master-slave modes for low-level debug of serial links

Methods and apparatuses for detecting an in-band reset using digital circuitry. A first counting circuit is coupled to receive a first clock signal and to generate output signals based on a number of cycles of the first clock signal. A second counting circuit is coupled to receive a second clock signal and the output signals from the first counting circuit. The second counting circuit generates output signals based on number of cycles of the second clock signal. A comparison circuit is coupled with to receive the output signals of the second counting circuit and to generate a reset signal if the output signals from the second counting circuit correspond to a pre-selected range.
