How to perform pole zero analysis with spice3f?

I'm trying to perform pole zero analysis with spice3f.
This is the circuit file:
test
vin 1 0 dc 0 ac 1
r1 1 2 1
c1 2 0 1
r2 1 3 1
c2 3 2 1
..print ac v(3)
..pz 1 0 3 0 VOL PZ
..ac dec 20 10m 10k
..end

When I run Spice3F5 I always get the message:
Error: no data saved for pole-zero analysis; analysis not run

The user manual also tells to use the 'print all' command but supplies
no examples of how to that.

any help welcome

Isn't the print all on the printer? if not Go back to the computer
program look at the top left hand corner of the monitor.There should be
a menu bar there. Go to file left click "FILE" and hit print or print
all. If you are in the command line type PRINT ALL in the command line.
If you are in windows go to Start, RUN, Type "print all".

I'm not familiar with Spice3f, but I'd hazard a guess that you need a
statement of the form:

..print pz ...

Read the manual ?:)

It's a version which I installed on Debian Sarge as follows:

apt-get install termcap-compat

So it's as I suspected: You just downloaded some unknown code and --

Since you're a Linux head, I suggest you switch to NGSpice. It's
open-source, available for $0.00, and is actively worked upon (and
therefore has fewer trivial bugs like yours). Get it

I installed ngspice and it produces exactly the same error as the other

it is once more:

Hi Hugo !

I just copy/paste test.cir and run it on ng-spice. It runs !
I suggest you to install ng-spice on your system. It is well known that
the original spice3f5 is quite buggy.

For further informations i suggest you to compile ngspice with xspice
extensions (./configure .... --enable-xspice) to enable poly()
constructions. May be other usefull extensions are required, it depends
what are your needs with ngspice.

Please read carrefully the output of ./configure --help in the ngspice
package.

Hope it helps !

Hello Habib,

What is the result of the PZ-analysis with ngspice?

Best regards,

Helmut,

I think I know where you are going with your question.....

Upon reflection, I believe that PZ analysis -- along with noise
analysis -- is one of the things ngspice doesn't do yet. Even in
ngspice it's still broken, if I am not mistaken. I recall trying it
out a few years ago and not getting any answer. I haven't tried it
recently, so things might have changed, but OTOH I have seen no
activity about it on the development list, nor in the code (not that I
look a lot).

For the OP: Our suggestion is to try another SPICE program, for
example LTSpice from Linear Tech.

HTH,

Hello Stuart,

I wondered that Habib hasn't presented a result. It would be of interest
to know whether PZ-analysis of SPICE calculates useful numbers for the
discussed circuit.

LTspice doesn't have PZ-analysis.

Helmut

I can recall a specialty calculator/computer in the early '70's that
could do PZ extractions. Can't remember the name now but, IIRC, they
were a Tek spin-off.

I configured ngspice with --enable-xspice and installed it (make, make
install). However when I try to simulate my circuit, only AC-analysis
is performed correctly, concerning pole-zero analysis, I still get the
message:
Error: no data saved for pole-zero analysis; analysis not run

I also tried to configure it with --enable-pzdebug the resulting
executable however also does not work properly for pole-zero analysis
with my circuit

Could you please tell me which options you enabled for configuring
ngspice. Is it also possible to show me a fragment of the result of the
pole-zero analysis you got.

with my circuit

Could you please tell me which options you enabled for configuring
ngspice. Is it also possible to show me a fragment of the result of the
pole-zero analysis you got.

I have been installed ngspice with xspice enhancement and (may be) with
other like readline ... i did not remeber exactly.

Here the result of your test circuit :

Hello Habib,

Until now I always used ngspice like this
ngspice <complete_spice_input_file

I think you use it interactively and not in batch-mode like I did until
now.

Do you just make a file with a netlist+title and then start ngspice
like this?
ngspice file_with_netlist_and_title_line.net

This is what happens with my version:
ngspice file_with_netlist_and_title_line
ngspice 1 -> ac dec 20 0.01 10
Doing analysis at TEMP = 300.150000 and TNOM = 300.150000

No. of Data Rows : 61
ngspice 2 -> pz 1 0 3 0 VOL PZ
Warning: no such parameter on this device

no such parameter on this device

Could you tell which commands you enter?

I'm trying to perform pole zero analysis with spice3f.
This is the circuit file:
test
vin 1 0 dc 0 ac 1
r1 1 2 1
c1 2 0 1
r2 1 3 1
c2 3 2 1
.print ac v(3)
.pz 1 0 3 0 VOL PZ
.ac dec 20 10m 10k
.end

When I run Spice3F5 I always get the message:
Error: no data saved for pole-zero analysis; analysis not run

The user manual also tells to use the 'print all' command but supplies
no examples of how to that.

any help welcome

hugo

Hi Hugo !

I just copy/paste test.cir and run it on ng-spice. It runs !
I suggest you to install ng-spice on your system. It is well known that
the original spice3f5 is quite buggy.

For further informations i suggest you to compile ngspice with xspice
extensions (./configure .... --enable-xspice) to enable poly()
constructions. May be other usefull extensions are required, it depends
what are your needs with ngspice.

Please read carrefully the output of ./configure --help in the ngspice
package.

Hope it helps !

Habib
thanks for the reply,
you're welcome.
I configured ngspice with --enable-xspice and installed it (make, make
install). However when I try to simulate my circuit, only AC-analysis
is performed correctly, concerning pole-zero analysis, I still get the
message:
Error: no data saved for pole-zero analysis; analysis not run

I've installed ng-spice-rework revision 17 on my debian machine.
What is the result of ngspice --version on yours ?

Are you sure ./configure-make-make install process worked well ?

I also tried to configure it with --enable-pzdebug the resulting
executable however also does not work properly for pole-zero analysis
with my circuit

Could you please tell me which options you enabled for configuring
ngspice. Is it also possible to show me a fragment of the result of the
pole-zero analysis you got.

mmh ... ok, when i do ngspice -b your_very_simple.cir

I think you use it interactively and not in batch-mode like I did until
now.
Yes of course because i want to do "print all" in order to make PZ

analysis !!! (do this "? .pz" within ngspice)
Do you just make a file with a netlist+title and then start ngspice like
this?
ngspice file_with_netlist_and_title_line.net

This is what happens with my version: ngspice
file_with_netlist_and_title_line
ngspice 1 -> ac dec 20 0.01 10
Doing analysis at TEMP = 300.150000 and TNOM = 300.150000 Warning: vin:
has no value, DC 0 assumed

No. of Data Rows : 61
ngspice 2 -> pz 1 0 3 0 VOL PZ
Warning: no such parameter on this device

Strange,
no such parameter on this device

pz simulation(s) aborted

strange.

Could you tell which commands you enter?

Hello Habib,

You reported in a previous reply the result of the PZ-analysis.
How have you achieved that?
I see an error message about PZ-analysis in your report above.

Best regards,
Helmut
