Dear Sir/Madam,

 

I have replaced the examples' spectre.mod file so that it will point to
my own .scs model file. Right now, my own spectre.mod file only has one
line : 

include "/usr/../../../ag100_mos.scs" section=nom

 

However, when I run the s2ibis software, it does not seem to recognize
the model file and keeps on giving error that my component is of
undefined model.

 

Kindly advice.

 

Thank you.

 

Best regards,

Mei Yee

Dear Sir/Madam,

 

I am an analog IC design engineer currently learning how to generate
IBIS models for my circuit. I have downloaded s2ibis2 v1.1 and tried
running some examples from there. However, there are some questions that
I would like to be clarified:

 

1)       I'm using a spectre simulator and my circuit and model files
are also meant for spectre language. I noticed that the command input
file (.s2i) takes in a spice (.sp) file, which is rather similar to the
spectre netlist. Is it possible to run the software using my spectre
netlist as input? Or do I need to generate a spice-compatible netlist
file?

2)       I also have my own model files (.scs). Can I replace the
example's spectre.mod with my own model file and change the extension to
.mod? 

3)       The s2ibis2 software helps me to run all the necessary
simulations and convert them to ibis format automatically. Is there any
other method where I can use my own simulation output and convert them
into ibis format? i.e. is there any converter which takes in simulation
output data and converts them into ibis file?

 

I hope that my questions are not confusing. Your feedback and assistance
are highly appreciated.

 

Thank you very much in advance.

 

Best regards,

Mei Yee
