Abstract
A circuit for measuring latency in an integrated circuit device is described. The circuit comprises a transmitter circuit having signal generator configured to generate a test signal having a marker for determining a latency in a path associated with the integrated circuit device; and a latency calculation circuit coupled to the signal generator and having a latency adjustment circuit and a unit interval (UI) adjustment circuit; wherein the latency calculation circuit generates a latency value (LATENCY) based upon a latency count from the latency adjustment circuit and a UI adjustment from the UI adjustment circuit.
