Patent ID: 7411862

Claim:
A control signal training system in an integrated circuit, comprising: a signal transmitting unit for 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 for latching control signals in relation to the sampling clock signals; a control signal transmission bus connected to the signal transmitting unit and the signal receiving unit, the control signal transmission bus being configured for transmitting control signals from the signal transmitting unit to the signal receiving unit; a sampling clock signal transmission line connected to the signal transmitting unit and the signal receiving unit, the sampling clock signal transmission line being configured for transmitting sampling clock signals from the signal transmitting unit to the signal receiving unit; a reading unit connected to the signal receiving unit, the reading unit being configured for reading the control signals latched in the control signal receiving unit, and an evaluation unit connected to the reading unit and the signal transmitting unit, the evaluation unit being configured for 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 being further configured for 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.
