Abstract:
1. A method comprising: generating a first transition on a first line of a source synchronous link to cause a first reflection on said first line; subsequently generating a first crossing pulse on said first line and generating a second crossing pulse on a second line of said source synchronous link, said generating said second crossing pulse performed concurrent with said generating said first crossing pulse, said second crossing pulse having an opposite polarity of said first crossing pulse; receiving said first crossing pulse and said second crossing pulse in a receiving circuit coupled to said first line and to said second line generating a third crossing pulse on said first line; generating a fourth crossing pulse on said second line, said generating said fourth crossing pulse performed concurrent with said generating said third crossing pulse, said fourth crossing pulse having a same polarity as said third crossing pulse; and verifying that signals on said first line and said second line are correctly received in said receiving circuit.
