Examples of Wildcard Usage in Subcircuit Instances
• The below specifies that the node X1.1 will be probed:
.PROBE TRAN V(X1.1)
• To plot all nodes in subcircuit X1:
.PLOT TRAN V(X1.*)
• To store all currents in devices internal to the Xbias instance:
.PROBE TRAN I(Xbias.*)
Specifying Simulation Output
Using Wildcards for Plotting and Probing
• To plot all the nodes of subcircuit X1 but not probe internal nodes of the subcircuit
hierarchy:
.PLOT TRAN V(X1.*)
• Use the -R parameter to probe all internal and external nodes of subcircuits beginning
with the name X1:
.PROBE TRAN -R V(X1.*)
This can also be performed using the VX keyword.
• To probe all nodes of subcircuit X1 and enter inside the n level of hierarchy under X1
for plotting nodes:
.PROBE TRAN -Rn V(X1.*)
If n is 0 this specifies the top level.
• To plot all nodes of subcircuit X1 and enter inside the n level of hierarchy under X1 for
plotting nodes.
.PLOT TRAN -R LEVEL=n V(X1.*)
If n is 0 this specifies the top level. Equivalent to -Rn.
Note
.PLOT TRAN V(X1.*) is equivalent to: .PLOT TRAN -R0 V(X1.*)
• VX, IX and ISUB can be used to probe voltages and currents on all subcircuit input
nodes within the hierarchy. For example, to probe the current across all input nodes of
subcircuits beginning with the name X1:
.PROBE TRAN IX(X1.*)
• Waveform definitions (defwaves) and digital quantities can also be probed for subcircuit
instances using wildcards:
