ABSTRACT:
A control signal training system in an integrated circuit comprises a signal transmitting unit, the signal transmitting unit outputting control signals and sampling clock signals, the control signals and the sampling clock signals having a predetermined time phase with respect to each other, a signal receiving unit, the signal receiving unit latching control signals in relation to the sampling clock signals, and an evaluation unit connected to a reading unit and the signal transmitting unit, the evaluation unit determining concordance of the control signals outputted by the signal transmitting unit and the control signals read out by the reading unit from the signal receiving unit, the evaluation unit adapting the time phase between the control signals and the sampling clock signals step-by-step until concordance of the control signals outputted by the signal transmitting unit and the control signals read out the reading unit from the signal receiving unit is determined by the evaluation unit.
