Scope of Initialization Controls

.NODESET and .IC statements at the outer level of the netlist can reference nodes that are defined in the top-level circuit directly, as in the examples above.

.NODESET and .IC statements at the outer level of the netlist can also use hierarchical names to reference nodes within subcircuit instances. For example:

.SUBCKT test in out
R1 in middle 100
R2 middle out 200
.ENDS test

Xtest 1 2 test

.NODESET V(Xtest.middle)=5

.NODESET and .IC statements inside a subcircuit definition apply only to those nodes that appear within the subcircuit definition. For example:

.SUBCKT test in out
R1 in middle 100
R2 middle out 200
.NODESET V(middle)=6
.ENDS test

In this subcircuit definition, the voltage on node middle will be initialized at 6 volts in all instances of the subcircuit. Since the .NODESET is internal to the subcircuit definition, the node it references is treated as a subcircuit internal node.
