S-parameter model

[Verictor]

Hi,

I know this question isn't for Cadence. But it will be helpful if
someone can direct me to the right place.

My question is: how do I use a 4-port S-parameter file in HSpice. In
Cadence we have nport module. What is the counterpart in HSpice? The S-
parameter file is in blackstone format.

Thanks a lot

In HSPICE this is the "S" element, described as the "Frequency-Dependent
Multi-Terminal (S) Element".

See the hspice documentation for more details.

Andrew, can you please point me to any documentation that will guide me on how to use the n1port (older version) component? All the information I'm finding speaks to the newer component which allows for the user to simply point to a file containing the S-Parameters....but my version asks me for a model.

Thanks
Andy

Hi Saurabh,

There is the nport component in analogLib (or n1port, n2port, n3port, n4port
if you're using an older version) which allows you to specify a file of
frequency dependent s-parameters (in spectre's own syntax). There is
a tool, sptr, which can convert from various formats into spectre's own.

Regards,

Andrew.

Hi!

Is there any component in the Cadence default library which implements a
s-parameter block (in which I could give the fixed/frequency dependent
s-parameter values and the block would provide me with the expected I/O
characteristics). I am looking for something like the 'lna' cell view in
the 'rfLib' library which gives a verilogA model for an lna.

thanks,
saurabh

Andy,

You didn't say which version of the IC tools or MMSIM that you're using,
but nport has been in analogLib for a really long time - the only real
difference is that it allows you to specify the number of ports and the
symbol changes dynamically.

You should just be able to use n1port and only fill in the s-parameter
file name; no need to specify anything else (assuming you're using a
recent MMSIM version such as MMSIM12.1 or MMSIM13.1; a lot of work has
been done to try to ensure nports simulate as "out of the box" as possible).

I don't see any version asking for a "model" - so I'm slightly confused
by that...

Regards,

Andrew.

Andrew, thanks for the reply, I wish I could post a screen shot....but it doesn't look like I'm able to. How can I find out which version of MMSIM I'm using? The only version related information I was able to find is: spectre (ver. 5.10.41_USR5.053107 -- 31 May 2007).

Best
Andy

By the way, correction to my previous statement...I'm actually using "n1port" because "nport" doesn't appear in my "Analog_Parts" library.

Hope this clarifies things a bit...

Hi Andrew, I was able to load a screenshot onto a Cadence forum:

http://www.cadence.com/Community/forums/p/29000/1332802.aspx#1332802

I think I asked this in my prior post, but just in case I didn't....how can I check which version of MMSIM I'm using?

Program: @(#)$CDS: icfb.exe version 5.1.0 06/20/2007 02:13 (cicln03)
