Simulate LM358 Spice model import

Schematic Simulation (Ngspice)
1

Hi, I need some help simulating an circuit with the LM358 Opamp. I want to see if there is an instable oscillation problem.
I found two Spice models of the device an I decided to go with the more complex one from TI:
I downloaded the SICE model file from here:
http://www.ti.com/product/LM358/toolssoftware

My Kicad version:

I modified the shipped LM358 symbol from kicad to have the VCC(4,V+) and VEE(5,V-) because the default was missing both. Then I entered the alternate node sequence to match ā€œ.subckt LMX58_LM2904 IN+ IN- VCC VEE OUTā€ from the lib file.

If I then press ā€œsimulateā€ I get a whole lot of errors:

Where to start? I guess I need to transform the if statements to c style format ā€œa ? b : cā€ ā€¦ But if I succeed is it possible at all to get this file to work with kicad?

You need to set the PSPICE compatibility flag,

set ngbehavior=ps

see http://ngspice.sourceforge.net/ngspice-eeschema.html

Damn, I cheered to soonā€¦
I simplified my circuit,

ngspice fails to catch the dc operating point before starting the transient simulation.

The OpAmp tries to zero the voltage difference between its input nodes 3 and 2 by a suitable output voltage at node 1. With the circuit and the resistor parameters chosen, the diference would be zero if the output was 6V, the power supply voltage. The LM358 bipolar OpAmp, however, can never output a voltage up to its supply rail. Thus the output is saturated somewhere below the supply, Then the difference between nodes 3 and 2 is not 0. Depending on the model, this may be not a good starting point for iterating the operating point.

Try increasing R3, just to find a starting point. And perhaps make the circuit symmetric by adding a negative supply to pin 5.

May be the GND is not been treat as ngspice GND. You may try to replace the GND by connect them to a net named ā€œ0ā€ (Zero). It may help, because ngspice to not understand net named ā€œGNDā€ as the global zero volt reference.

Can you paste your SPICE netlist so we can take a look?

For dealing with convergence problems from manufacturer supplied models, you might need to utilize the .ic or .nodeset commands. Adding uic to the .tran command might work too in specific scenarios. All this nonsense is covered on page 253 of the ngspice manual: http://ngspice.sourceforge.net/docs/ngspice-30-manual.pdf

If you keep running into problems, and you just need a basic analysis of your circuit, you might be able to get away with just using a simpler model. Below is a basic single pole opamp subcircuit. It doesnā€™t consider the rails, so any type of input or output saturation wonā€™t be simulated. Just change the value of GBWP in the .subckt line with the gain-bandwidth product from the datasheet of your opamp. For even better modelling you can change Rin, Rout, and Aol (open-loop gain) with values found or derived from the datasheet too. You can copy this text into a .lib file and use it in your schematic with the proper SPICE node sequence set (2,3,1 for your LM358).

* single pole opamp model
* 1 = inverting input
* 2 = non-inverting input
* 3 = output
.subckt opamp 1 2 3 params: Rin=1g, Rout=1m, Aol=1g, GBWP=100meg
R1 2 1 {Rin}
G1 0 3 2 1 {Aol}
R2 3 0 {Rout}
C3 3 0 {Aol/(2*3.1415926536*GBWP)}

Base on the log message, and the output I think you did not use the simple model from @Ste.

Can you do eeschema -> Tools -> Generated Netlist Fileā€¦ -> Spice (Tab) -> Generate Netlist (Button) ā€¦ Then show the content of that netlist file here may be.

11

Using that simple model would not work well in this case since he is using the amplifier in open-loop as a comparator. Rail saturation is vital for that mode of operation.

I ran @Val 's simulation, and I get a completely different result. First, here is the netlist as requested:

.title KiCad schematic
.include "LMx58_LM2904-ti.lib"
.include "led.lib"
V1 +5V 0 pulse(0 5 0 1m 1m 10000)
V2 +5V_pulses 0 pulse(0 5 100m 200m 150m 200m 800m)
XU3 +5V_pulses Net-_R11-Pad2_ +5V 0 Output_3 LMX58_LM2904
R11 +5V Net-_R11-Pad2_ 100k
R12 Net-_R11-Pad2_ 0 100k
R13 +5V Net-_D5-Pad2_ 620
D5 Net-_D5-Pad2_ Output_3 LED_RED
.TRAN 0.0001 1 0
.end

It looks like his system is unable to properly parse these 5 model lines from the .lib file, while my system has no issue doing it:

.MODEL S_VSWITCH_1 VSWITCH (RON=10M ROFF=1T VON=10M VOFF=0)
.MODEL S_VSWITCH_2 VSWITCH (RON=10M ROFF=1T VON=10M VOFF=0)
.MODEL S_VSWITCH_3 VSWITCH (RON=1M ROFF=1T VON=500M VOFF=100M)
.MODEL S_VSWITCH_4 VSWITCH (RON=50 ROFF=1T VON=500M VOFF=450M)
.MODEL S_VSWITCH_5 VSWITCH (RON=50 ROFF=1T VON=500M VOFF=450M)

I wonder if this has anything to do with his system being a Linux system??? I noticed that the .lib file from TI has Windows EOL characters instead of UNIX. That could be one source of the issue. It also might be worth removing the space between the VSWITCH and open parentheses in case that may be causing an issue too.

So the strange thing here is that his simulation which is missing these switch models is able to converge. My simulation which has no issue parsing these lines cannot converge, much like in @pauledd 's circuit. I also ran this LM358 model in LTspice and it has a difficult time converging there too. I have to use the ā€œAlternateā€ (high precision) matrix solver to get it to work, and it still takes a long time even just to get the operating point.

I think this brings up a great rule of thumb for anybody new to the area of SPICE simulation:

Use the simplest model that gets the job done.

The more complicated the model, the more likely youā€™ll run into issues in getting it simulate effectively. This TI supplied model is extremely complex, with all sorts of behavioral voltage controlled current & voltage sources. These are known to cause convergence issues. I remember working on a universal opamp SPICE model a few years ago which included rail saturation, but I never finished it. It might be worth going back to since it would be helpful in these situations. Just plug in a few values from the datasheet, and you got a pretty decent model for most situations.

The ngspice error message above the image:

Below the image:

Comparing the two error messages: Is this the same lib file? In the first message ngspice is looking for (and not finding) an aswitch. There is no aswitch in ngspice, PSPICE. Did you edit the lib file replacing vswitch by aswitch? This cannot work. The second message is obvious, because the PSPICE compatibility flag has not been set.

Sorry, I have been wrong, please see next post.

13

There is an aswitch in ngspice. It is part of the XSPICE analog/digital enhancement. You will need to enable XSPICE in your compilation setup to get access to these models. If you already have done so, the error messages seem to indicate that the code model installation is not correct.

These files are missing:

When I install from source at /usr/local (with ./configure ā€¦ ; make ; make install) they appear on /usr/local.

Why they donā€™t appear in the package? But in the package building instructions? Do they appear in the old version of the package?

No, they donā€™t appear in the original package from the repository:

So the configure step includes XSPICE.

Finally the code models are made and stored in library files analog.cm, digital.cm etc. KiCad does not use a spinit file (ngspice initialization file with ā€˜codemodel path/analog.cmā€™ commands) but searches itself for the code models in a dedicated directory. I am not on Linux, so I do not know this directory. Maybe a colleague here on the forum might help to identify the correct codemodel path for your system.

16

But these .cm files are missing even from the original package from the repository (libngspice-kicad_0.1-2~201710281402+2e5be8d~ubuntu16.04.1_amd64.deb).

Maybe a bug in the building instructions of the package libngspice-kicad?

Looks like the files are compiled, but not included in the package:

valentin@computer:~/src$ find -name digital.cm
./kicad-ngspice-build/ngspice-kicad-0.2.30/ngspice/src/xspice/icm/digital/digital.cm
./kicad-ngspice-build/ngspice-kicad-0.2.30/debian/tmp/usr/lib/x86_64-linux-gnu/ngspice/digital.cm
./ngspice-30/release/src/xspice/icm/digital/digital.cm
valentin@computer:~/src$

If I understand correctly (I am not familiar with the Debian package system) my guess is that the bug is in this file:

valentin@computer:~/src/kicad-ngspice-build/ngspice-kicad-0.2.30/debian$ cat libngspice-kicad.install 
usr/lib/*/libngspice*
usr/share/ngspice-kicad/*
valentin@computer:~/src/kicad-ngspice-build/ngspice-kicad-0.2.30/debian$

This line should be added:

usr/lib/ngspice/*

However, I am not sure what will happen when the user installs the ngspice package. There is a risk that the ngspice package will overwrite the same files.

Just checked it - yes, it will create a package conflict.

valentin@computer:/var/cache/apt/archives$ dpkg-deb -c ngspice_26-1build1_amd64.deb  | grep usr/lib

The old version of ngSpice (if installed) will overwrite the files in the /usr/lib/ngspice/ directory.

The solution is to rename the lib/ngspice/ directory in the source code. This will prevent the creating of a conflicting package.

Another guess: maybe --datarootdir=/usr/share/ngspice-kicad is not enough, also --datadir=/usr/share/ngspice-kicad should be included. Because I just read the Makefile and it does not make sense:

datadir = ${datarootdir}
datarootdir = ${prefix}/share

or

datadir = ${datarootdir}
datarootdir = /usr/share/ngspice-kicad

This does not make sense. The first line should be after the last.

Or maybe it will work, I am not familiar with how make is working. But itā€™s logical that lines are interpreted from the top to bottom. And at the first line ${datarootdir} is not defined (maybe itā€™s default).

The newest version of ngspice (when built with configure --with-ngshared) is making a binary called cmpp. Is this program needed for KiCad? Do I need to include it in the libngspice-kicad package?

19

cmpp is required during making the XSPICE code models. When they are compiled and available, and a user should not make and add his own code models, then cmpp is not needed anymore.

20

I assume that KiCad will not call the cmpp binary, the cmpp will be called by the user. So, there is no need cmpp to be included in the libngspice-kicad package, the user can install the ngspice package if he want to use cmpp.
