Commands
.PROBE (Probe)
Purpose
The .PROBE command writes the results from DC, AC, and transient
analyses to a data file used by Probe.
General form
.PROBE[/CSDF][output variable]*
Examples
.PROBE
.PROBE V(3) V(2,3) V(R1) I(VIN) I(R2) IB(Q13) VBE(Q13)
.PROBE/CSDF
.PROBE V(3) V(R1) V([RESET])
.PROBE D(QBAR)
The first example (with no output variables) writes all the node voltages
and all the device currents to the data file. The list of device currents
written is the same as the device currents allowed as output variables.
The second example writes only those output variables specified to the
data file, to restrict the size of the data file.
The third example creates a data file in a text format using the Common
Simulation Data File (CSDF) format, not a binary format. This format is
used for transfers between different computer families. CSDF files are
larger than regular text files.
The fourth example illustrates how to specify a node that has a name
rather than a number. The first item to output is a node voltage, the
second item is the voltage across a resistor, and the third item to output
is another node voltage, even though the second and third items both
begin with the letter R. The square brackets force the interpretation of
names to mean node names.
The last example writes only the output at digital node QBAR to the data
file, to restrict the size of the data file.
Arguments and options
[output variable]
This section describes the types of output variables allowed in a
.PRINT (print), .PLOT (plot), and .PROBE command. Each .PRINT or
.PLOT can have up to 8 output variables. This format is similar to that
used when calling up waveforms while running Probe.
