@User the order is determined by the order of pins in the symbol. if netlisting rule has

@pinlist

in the symbol '`format="..."`' attribute then the order is the creation order of the symbol pins. You can change this order: select a pin you want to be netlisted first (the small red square) in a symbol, press 'Shift-S' and set it's sequence number to zero (first pin). Then select the pin you want to be netlisted in second position , set it's sequence number to 1, and so on (see picture). A more flexible approach is to replace the

@pinlist

attribute with the explicit order of pins: for example for a NAND2 gate (inputs A,B, output Z) the format string should be something like:

format="@name @@A @@B @@Z @model ..."

or (for a subcircuit)

format="@name @@A @@B @@Z @symname"

. This way you get rid of any ordering of pins in the symbol. The

@@X

syntax means: "put the name of the net attached to the '`X`' pin'. The .subckt declaration and the instance call (X line) will consistently have the same and matching pin ordering.
