In a multi-service platform system ( 300 ), a method of skew adjustment can include providing an initiator VME module ( 302 ) coupled to a responder VME module ( 304 ) over a parallel multi-drop bus network ( 306 ). The initiator VME module communicates a calibration cycle ( 316 ) to the responder VME module during a calibration phase ( 208 ), where the calibration cycle includes a reference signal ( 322 ) and a training data signal ( 324 ) having a preset relationship ( 321 ), and where the calibration cycle is communicated using a source synchronous protocol ( 107 ). The responder VME module calculates a deviation ( 350 ) from the preset relationship of the reference signal and the training data signal, where the deviation comprises a delay time ( 325 ). The initiator VME module communicates a data signal ( 418 ) to the responder VME module during a data phase ( 210 ), where the data signal includes the reference signal and an actual data signal ( 426 ). The responder VME module delays one of the reference signal and the actual data signal by the delay time.
