Specifying Simulation Output
Using Wildcards for Plotting and Probing
The above example specifies the output of three nodes. Node x1.x2.n21 is created as the second
pin of resistor r20, which is an element of the subcircuit sc2, instantiated using instance x2,
which is itself nested in the subcircuit sc1, instantiated using instance x1.

Using Wildcards for Plotting and Probing
To analyze simulation results for huge circuits, and to display only part of the circuit, you can
specify a .PLOT/.PROBE command with nodes defined via both hierarchy and wildcard
characters. The wildcard (*) may be used to select any list of items for plotting/probing
quantities such as voltage or current.
If the wildcard * is specified, then Eldo enables it to be used in conjunction with ? and [ ] for
matching characters (see “Special Characters” on page 312). If * is not in the specification, then
? and [] are not supported; a warning will be generated. If you want to keep the [ ] inside the
name specification and not have Eldo handle them as special characters, then specify .OPTION
NOCMPUNIX or use the backslash delimiter.
Note
Option LIMPROBE can be specified to set the maximum number of nodes that may be
monitored via the .PROBE command. By default, it is set to 10,000.
Wildcards in Subcircuit Instances
Subcircuit instances can be specified in the output command. A specific subcircuit node can be
referenced or wildcards (*) can be used to select any list of items for probing quantities such as
voltage or current. Subcircuit instances can be specified for keywords V, I, S, W, VX, IX, ISUB
and POW. The following syntax is used to specify wildcards in subcircuit instances:
V|I|S|W|VX|IX|ISUB|POW(.*)
V|I|S|W|VX|IX|ISUB|POW(->*)
When specifying parameters V, I, VX, IX, ISUB, POW with a subcircuit instance the -R
parameter can also be specified to enter levels of hierarchy.
V(Xnn.*) — Monitors the voltage on all of the nodes of subcircuit Xnn.
S(Xnn.*) — Monitors the states on all of the nodes of subcircuit Xnn.
S(Xnn.Ynn->*) — Monitors the states on all of the nodes of macromodel Xnn.Ynn.
