This patch adds two features to the standard SpiceNetlister:
F1.) Allows you to disable a component from the Netlist. Useful for connectors etc. To exclude a component from the Spice Netlist add [Spice_Netlist_Enabled] user FIELD set to: N F2.) Allows you to adapt to simulation libraries that require the netlist node sequence to be in a different order. To reorder the component spice node sequence add [Spice_Node_Sequence] user FIELD and define sequence: 2,1,0 I am using LTSpice, but this holds true for any SPICE subcircuit.
