traces from specific loaded data files
If two or more data files have identical simulation output
variables, trace expressions that include those variables will plot
traces for each file. However, you can specify which data file to
use in the trace expression. You can also determine which data
file was used to generate a specific trace.
To add a trace from a specific loaded data file
1
In Probe, from the Trace menu, select Add to display the
Add Traces dialog box.
2
In the Trace Expression text box, type an expression using
the following syntax:
trace_expression@fn
where n is the numerical order (from left to right) of the data
file as it appears in the Probe title bar, or
trace_expression@s@fn
where s is a specific data section of a specific data file.

Click OK.

the source file for an individual trace
1
In the trace legend, double-click the symbol for the trace
you want to identify (Figure 17-3).
The Section Information dialog box appears, containing the
trace name and, if there is more than one data file loaded in
the plot, the full path for the file from which the trace was
generated. Also listed is information about the simulation
that generated the data file and the number of data points
used. If the trace is from a checkpoint data file, the dialog
box includes the checkpoint description (Figure 17-4).
or press UI
The Simulation Output Variables list in
the Add Traces dialo
g
box contains the
output variables for all loaded data files.
Example: To plot the V(1) output for
data section 1 from the second data file
loaded, type the followin
g
trace
expression:
V(1)@1@f2
You can alternately use the name of
lthe oaded data file to specify it. For
example, to plot the V(1) output for all
data sections of a loaded data file,
MyFile.dat, type the followin
g
trace
expression:
V(1)@"MyFile.dat"
