Names with the special characters ")", ",", "=" and blanks are not allowed.

Please rename the affected signals!

• Why not use ")": If formulas are used in the circuit, then possibly the formulas could not be evaluated clearly. Troubling example: Signalname "out)*2" used in formula "V(in)-V(out)*2)" would be regarded as a writing error for "V(in)-V(out)*2".

• Why not use ",": In SPICE signals can also be separated with a comma. Troubling example: Signal name "a1, b2" with signal sequence "... a1, b2, out... " would be regarded as a sequence of three signals.

• Why not use "=": An optional node in the header of a subcircuit must be written as "node=defaultnode". Troubling example: With "outx=1=G_1" the node could be "outx=1" but also "outx"!

• Why not use blanks: In SPICE the blank is THE SEPARATOR! Troubling example: "Q1 a 1 x y bc140" should be a SPICE line for the bipolar transistor Q1 with "a 1" as an individual signal, then SPICE will read four nodes a, 1, x and y, thus y is regarded as substrate and not as emitter!
