Abstract: A method for determining a round-trip latency of a communication channel in a system between a first device and a second device, comprising: setting an estimated round-trip latency binary value by the first device that represents a latency measured in clock cycles; generating and sending a first test signal by the first device comprising alternating first and second values, being sent at each clock cycle; saving each first and second value of the first test signal for a duration that corresponds to the estimated latency value; receiving the first test signal at the second device; sending, by the second device, a validating signal that is based on the first test signal; receiving the validating signal at the first device; and determining if the latency value is correct based on the comparing of the validating signal and the first test signal.
