Abstract
High Speed I/O interfaces such as DVI, S-ATA or PCI-Express require expensive test equipment. Loop-back tests are widely used as one alternative, but lack coverage of timing-related defects. A system and method for on-chip jitter injection using a variable delay with controllable amplitude and high accuracy is provided that improves the coverage of loop-back tests.
