Thread Summary

                The user encountered an error when trying to simulate a 4-terminal NMOSFET in LTspice using a model from the sky130a PDK. The issue was due to the model being a subcircuit library, not a simple model. The solution involved modifying the symbol to use an X device for the subcircuit and ensuring all required parameters were defined. The modified symbol and subcircuit are provided in the attached zip file.

Hi,


 


  I am trying to run a simple simulation with LTspice using a 4 terminal nmosfet and a model file (from sky130a PDK). I created a schematic with a generic 4 terminal device from the LTspice library and changed the model name of the device as per the the model name in the model file. I also added an .inc statement in the schematic to point to the model file.


 


 This approach works ok for any other model downloaded from the internet. However in this case I am getting the error:


 


Node or model name expected.


M1 N001 N002 0 0 sky130_fd_pr__nfet_01v8 l=0.15 w=1.260


                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


 


What could be the reason? What am I doing wrong?


 


 If you want to run the issue at your end and see, I am uploading the TC here. Just download the TC and hit the run button on the schematic.  


 


 Requesting someone look into the matter and advice.


 


Thanks,


Arvind Gupta

    same issue , i was trying to build Back-emf sub-ckt which contain my designed comparator .but spice throwing error 

    C:\Users\win11\Documents\LTspice\lib\sub\bemf-2.sub(16): This sub-circuit name is not defined. X§U3 0 ab 0 Vhigh hb MyComparatorOC .

    even though i stored MyComparatorOC at crt location. i even tested my comparator it was working well

    PLZZZZ FIX THIS ,THIS WAS SO IRRITATING

    HI  ,
    

    OK, there are a number of problems. Let's start at the top level: you do not have a .model card (definition); your "model" file is a subcircuit library, which is different.
    

    The M statement in Spice indicates that a model for a MOSFET will be defined. You have not provided a model for a FET, but instead a subcircuit as part of a library. (Within the subcircuit the model is defined (the .model statement). In summary:
    

    The (top-level) problem:
    

    You have:
    

    M1 N001 N002 0 0 sky130_fd_pr__nfet_01v8 l=0.15 w=1.260
    

    which requires a "model card", namely
    

    .MODEL sky130_fd_pr__nfet_01v8 NMOS (blah blah)
    

    The library file you have supplied does contain such a statement:
    

    .model sky130_fd_pr__nfet_01v8__model.0 nmos
    

    with hundreds of parameters defined.
    

    Problem is, you cannot simply add that model to your schematic because the model depends on parameters defined in its parent subcircuit.
    

    The (top-level) solution:
    

    Modify the symbol to be a symbol for a subcircuit, and X device, not an M device. Nice thing, is it looks the same. I've done this for you. See attached.
    

    Bigger Problem.
    

    The Subcircuit has quite a few undefined parameters, so it appears to be ill-formed, or you need more information.
