Node Names
A node name can contain any number of alphanumeric characters, and the following special characters:
! # $ % ^ * - + _ [ ] < > /
However, a node name containing a special character that also represents an arithmetic operator (- + * /) or a relational operator (< >) cannot be used in expressions, with or without quotes.
Node names can begin with one of the special characters
! # % _
Net names entered in the Schematic Editor may not contain spaces ( ), ampersands (&), or asterisks(*).
All node names in the Circuit solver are treated as strings, even when they appear as integers such as “12”. No numeric conversion is performed. For example, some simulators treat node “001” as node “1”. The Circuit solver treats these as two different node names.
