Timing uncertainty measurements on the Power5 microprocessor

On-chip timing measurement (Skitter) circuits are included on the Power5 microprocessor. By cross-coupling the 3 Skitter instances, the combined effect of jitter, skew, and supply noise can be measured for all cycles of a pattern or an application. System results show a maximum of 27ps timing impact...

Zusammenfassung:	On-chip timing measurement (Skitter) circuits are included on the Power5 microprocessor. By cross-coupling the 3 Skitter instances, the combined effect of jitter, skew, and supply noise can be measured for all cycles of a pattern or an application. System results show a maximum of 27ps timing impact on a 500ps path.
