error in the def "write_spice_subcircuit_s(self, z0, file: str) -> None: "

1111.txt

After performed the function of write_spice_subcircuit_s(z0, spice_filename), I get the .sp file(as shown in 1111.txt) and import it into ADS, but I have no idea to choose which netlist dialect.
I chose PSPICE and imported the file, but there is some warnings that remind me WARNING: Referenced circuit "1" not found. WARNING: Referenced circuit ""-1"" not found.
when I simulated circuit, there is an error "syntax error" in this line:
X1 nt11 0 rcl_vccs_admittance res=2.061 cap=347.907a ind=369.601a gm=970.280m mult=1
when I check the corresponding line in the impoerted circuit file (.net), I found that:
1:x1 nt11 0 rcl_vccs_admittance res "=" "X2.061" cap "=" "X347.907a" ind "=" "X369.601a"
gm "=" "X970.280m" mult "="

do you have some ideas about the error? can you please give me some instructions?

I don't know which dialects are available, but I can open the files in ltspice and ngspice

[yifan0407]

yes I found the file can be recognised by ITSPICE software, have you used Keysight ADS?

[FranzForstmayr]

No I haven't, sorry

It seems like ADS does not fully support regular SPICE netlists. See this example of a simple diode model:

The forums of Texas Instruments are also full of questions on how to include the SPICE netlists for the TI device models into ADS.

I don't currently have access to ADS anymore, but I remember they run their own vector-fitting routines when you include S-parameter blocks into a simulation. Of course, that only works if you can provide your network as a SnP file.

To summarize, I don't think this is an issue with the SPICE netlists exported with VectorFitting.write_spice_subcircuit_s(), but rather an ADS issue.
