Abstract
A technique for adjusting a communication system involves a link, where the link includes a data line arranged to transmit a data signal and a clock line adapted to transmit a clock signal. The technique uses one or more counters to test the transmission across the link. Dependent on one or more of these counters, a test circuit, connected to the link, compares a known test pattern signal to a latched test pattern signal transmitted on the data line. The test circuit includes an adjustment circuit arranged to generate an adjustable clock signal from the clock signal, where the adjustable clock signal determines when to latch the transmitted test pattern signal The test circuit adjusts a timing of the adjustable clock signal relative to the data signal of the link.
