5.1.3 Plotting From ChipMan
The ChipMan software has the ability to plot register values in real-time, up to 10Hz continuous rate.
To select a register to plot, highlight its name or value, and right-click. A menu with a single entry "Add
register to Plot" will appear (
Figure 5.6, "Plotting from the ChipMan" ). Click the entry then a plot window
should appear, with a legend on top. When additional registers with the same data type are selected,
they are added to the existing plot window. In the experiment shown in
Figure 5.7, "Plot Windows" ,
Drive Setting, TACH Target, and TACH Reading were selected. Note both the Tach registers are being
plotted on the same graph.
The last step is to start the plots. All plots can be started simultaneously by selecting the "Control"
pulldown from the main application window and then "Plot -> start all plots". Individual plots may be
paused at any time without loss of captured data on the other plot windows.
