Help!!, Spectre error: Illegal library definition found in netlist for TSMC 180nm

Omar Alngar

Dear All,
When I want to start simulation with spectre the error says:
Fatal error: Illegal library definition found in netlist
I set the model file correctly, but I don't know why it errors!
I opened the ADE>>Setup>>Model library
and I tried to modify the path of models file (SCS files)
It gives me "Illegal library definition found in netlist"
Thanks.

    Hi Omar,

    In older versions of Spectre (prior to SPECTRE17.1 ISR7) this gave this message when you tried to include a model file which was defined with library/section blocks and you didn't specify the section to include. In later versions it now says this in the error:

    Error found by spectre during circuit read-in.
    ERROR (SFE-675): "mymodels.scs" 4: Cannot run the simulation because a library
    file was included in `mynetlist.scs':4 without a section name. Add a valid
    section name in the include statement and rerun the simulation.

    If you look in the model files, you'll see something like:

    library someName
    section tt
     ...
    endsection tt
    section ff
     ...
    endsection ff
    endlibrary someName

    On the model libraries form in ADE, you must specify which section you wish to include, otherwise it gives the error.

    Andrew.

    Great Thanks, I actually solved this issue as you mentioned in your comments.

    and worked with these models correctly.
