SPICE Netlist length limit

Hi,

I'm generating SPICE Netlist in .cir extension of a large circuit (R,L,C,G) using passive components, using a third party-software (CST STUDIO). When I create a new component model in Multisim it seems that the netlist content can't be contained in the dedicated field.

Reducing the model (less components) solves the problem but results in significabg inaccuracy, I still want to use the first model.

I can't seem to find any indication regarding the length limit of a SPICE Netlist in Multisim documentation.

Does such limitation exist or is this a known issue?

On the Multisim SPICE Reference Manual, on page 6, the Netlist Parameters don't show a limitation.
