Figure 12 - Shows statistics from histogram measurements of Skew or
Propagation delay between two or more channels.
This tool is useful for measuring the skew between two or more signals. One example is
the propagation delay through a part from input to multiple outputs such as a clock fan
out. The example above shows the skew referenced from Channel 1 to Channels 2 and
3. A window or guide can be enabled to quickly identify if all channels occur within a
specified amount of time from one another.
