    Hi all,

    This is my first post at this forum so I'm hoping it is a good experience :)

    I am using LTSpice, have created a symbol for LM13700, followed all the instructions, and are encountering an error when I try to simulate

    Too many parameters for subcircuit type "lm13700/ns" (instance: xu1)

    Please find attached the model file and subcircuit symbol. To recreate the error, place the model file into \LTC\SwCADIII\lib\sub\myLib and symbol into LTC\SwCADIII\lib\sym\myLib folder.
    Open a new schematic, place the LM13700 and try to simulate.

    Thank you for your help.

    I don't know how many things are wrong but the most glaring one is that your model file does not have the output buffer included.
    Attached are the LM13700 files I have used successfully. The buffer is a separate symbol and model file.
