On-chip virtual oscilloscope using high-speed receiver sampler readback

A method, comprising:

• receiving, at a receiver, a set of bits corresponding to a pattern, wherein the pattern is associated with a signal having one or more levels;
• generating, at the receiver, a first plurality of digital values from a first portion of the set of bits, each digital value generated at a first timing value and a plurality of reference voltages, wherein a reference voltage of the plurality of reference voltages is incremented based at least in part on generating a digital value of the first plurality of digital values;
• generating, at the receiver, a second plurality of digital values from a second portion of the set of bits at a second timing value and the plurality of reference voltages, wherein the first timing value is incremented to the second timing value based at least in part on generating the first plurality of digital values;
• and
• determining an amplitude associated with the first plurality of digital values and the second plurality of digital values based at least in part on generating the first plurality of digital values and the second plurality of digital values.

A device, comprising:

• a receiver coupled with a link, the receiver to:
• receive a set of bits corresponding to a pattern, wherein the pattern is associated with a signal having one or more levels;
• one or more samplers coupled with the receiver, the one or more samplers to:
• generate a first plurality of digital values from a first portion of the set of bits, each digital value generated at a first timing value and a plurality of reference voltages, wherein a reference voltage of the plurality of reference voltages is incremented based at least in part on generating a digital value of the first plurality of digital values;
• generate a second plurality of digital values from a second portion of the set of bits at a second timing value and the plurality of reference voltages, wherein the first timing value is incremented to the second timing value based at least in part on generating the first plurality of digital values;
• and
• a controller coupled with the one or more samplers, the controller to:
• determine an amplitude associated with the first plurality of digital values and the second plurality of digital values based at least in part on generating the first plurality of digital values and the second plurality of digital values.
