Abstract
A system and integrated circuits are provided for determining performance metrics over a plurality of cycles of an input signal using on-chip diagnostic circuitry. The system comprises a trigger generation module configured to generate a trigger signal, and diagnostic circuitry coupled with the trigger generation module. The diagnostic circuitry comprises a memory comprising a plurality of data lines, and a plurality of delay elements, each delay element of the plurality of delay elements connected between consecutive data lines of the plurality of data lines. The diagnostic circuitry is configured to receive at least one input signal, and write, upon receiving the trigger signal, values on the plurality of data lines to the memory, thereby acquiring samples of a plurality of cycles of the input signal.
