Waveform Window
View Delta Cycles
When you expand a time, a delta cycle area is inserted into Waveform
and Timescale panes at the time currently pointed at. Refer to
Figure
4-6, Sample Delta Cycle Region. Only cycles that have changes on
signals active in the window are displayed, and the cycles are evenly
spaced. Spacing for delta cycles is controlled with the
VirSim*deltaCycleWidth variable in the Resource file, refer to
Chapter
16, VirSim Setup. The default is 8 pixels.
When you change the precision or units of the Waveform Window, all
current delta cycle regions are collapsed. If there are any files open
with a loss of precision with respect to the current display precision,
delta cycle is disabled (insensitive) until the precision changes.
Note:
Delta cycle waveform areas do not zoom.
The group displayed in the Waveform Window might contain a mixture
of signals with and without delta cycle information (for example, if
some displayed signals are from a file for which delta cycle information
was not saved). In this case, any edge for a signal without delta cycle
information appears in the last delta column. This column has an
asterisk above the tick in the timescale region. If you move the mouse
over this column, the status bar gives a time such as 12,350 dNA
indicating delta cycle data was not available.
