e voltage jitter 0 00 ns design skew between b u00e2 u2020 u2032 c and d u00e2 u2020 u2032 e note as stated in the above paragraph for this example there is no design skew this an unlikely event in a real design however one can see how in an actual design design skew is considered the maximum additional skew is evident when path d u00e2 u2020 u2032 e operates at bc voltage 0 9 ns and path b u00e2 u2020 u2032 c operates at wc voltage 1 2 ns note that the 0 3 ns difference is less than the 0 4 ns range in arrival times for sinks at point e which vary between 0 9 ns and 1 3 ns the improvement is possible because balancing considered both bc and wc timing modes rather than just a single timing mode table 4 shows two signal balancing examples and the corresponding range of signal arrival times the last two columns illustrate balancing at a specific operating condition here the voltage domains were balanced assuming each voltage domain operates at wc voltage during operation if every voltage domain operates at wc voltage total signal skew due to voltage effects is non existent however if path d u2014 gt e.
