I am getting fed up with lugging a laptop around when I also use a
tablet....

I would love an Android version of LTspice (which I know is highly
unlikely), or failing that, a good SPICE for tablet use...

Thanks

Nick

PS. Anyone know of any decent Android PCB layout/routing packages...?

Per John's suggestion, the following email was sent to Mike.

Dear Mr. Engelhard,

LTspice is fantastic! I evaluated many alternatives before I selected it. While the price was definitely a factor, the ease of use was the major issue. The user interface is intuitive, simple yet powerful. Well done.

A feature that would be extremely helpful is the "Option to preserve/reload plot settings after simulation run." The Yahoo! LTspice user group has a thread on this subject. They have explained it better than I can. A work around has been proposed in the thread (assigning reload plot to the space bar) helps but its no substitute for having the feature integrated.

I have LTspice IV, Ver 4.19i, running on Windows 7 Home Premium.

Keep up the good work.

Al

Well, this is no new proposal, and I'm sure Mike is well aware of the
'want'. But it won't come by discussing it here.

Helmut,

Edit Plot Defs File works when I open LTspice as Administrator in Windows 7. Thanks... but now LTspice is not using the plot.defs file I created.

I edit the file using the Edit Plot Defs File. After making changes to the file, I save, close and reopen the file. The changes are all there but LTspice is not using the file when I Run a simulation. It appears to be using the Autoranging EVERY TIME I Run a simulation, even though I have unchecked Plot Settings&#92;Autorange.

I have looked through the menus to see some master toggle for Autoranging feature but can't find anything.

I verified that the code in the file actually works copying the file to another name. It runs fine when I use Plot Settings/Open Plot Settings File and the selecting the file.

FYI, the code looks like this:
[Transient Analysis]
{
Npanes: 1
{
traces: 1 {268959746,0,"V(n001)"}
X: ('n',1,0,5e-010,6e-009)
Y[0]: (' ',1,-4,0.2,4)
Y[1]: ('_',0,1e+308,0,-1e+308)
Volts: (' ',0,0,1,-4,0.2,4)
Log: 0 0 0
GridStyle: 1
}
}





Thank you for your expertise!
Al

I'm using LTspice version 4.19i and can not get "Edit Plot Defs File" to work. I don't know if this feature existed or worked on earlier versions or not.

After I Run a simulation, I click on the .raw window to activate the window. Click "Plot Settings" and then "Edit Plot Defs File." Get error message, "Trouble creating file: C:&#92;PROGRA~2&#92;LTC&#92;LTSPIC~1&#92;plot.defs."

I did a search on my harddrive for plot.defs. Not found. Everything on else on the LTspice seems to be working fine. I just hate the default settings for the plots (including FFT plots).

Yes I have been successfully using "Save Plot Settings" and "Reload Plot Settings" on this version. But I'd really like to change the default settings if there is a means of getting the feature to work.

Cheers!

Hello Al,

I think there is an acceptable workaround.
Run LTspice as an administrator when you want edit plotdefs.
Later you can run it normally when you only want execute a plot
function.

Best regards,
Helmut

Windows Vista, 7 and 8 do not allow programs to create files in Program
Files folder. Without more knowledge of how your files are organized, I
can't tell you how to overcome this. The Path above is written for DOS -

Hallo Tim,

Thank u very much for the message, i know that i can use python to
write the script. but i don't know how should i programm then i can
use the python to call LTspice. can you show me an example? or just
how should i script? i cant find it in the internet. thanks again!

regards
Yang

This can be done using Python (or bash scripting), and examining the net
list, and modifying the appropriate value on the R line for the variable
resistor, and calling ltspice to run the simulation.

I understand not wanting to use the .op command, but it is really much
easier to use, and you can vary up to three (3) parameters with it.

I have

even seen ways to access a table which allows you to vary more than 3
parameters.

How through external program calls LTspice, I would like a variable
resistor value from 0 to 100K, a variable power supply

simulation. do not

use LTspice's . Op statements. But through external programming.

Some

people know which software and how programming?

You could write a program that builds netlists for you and then runs
LTspice with the netlist it just created.

I went looking on the eagle forums for answers on this too only to find that it looks like the eagle forums are no longer there.

what link are you using to get to the eagle forums now ? even if unanswered ?

thanks,

Some background, not intended to be criticism, then the question.

Cadsoftusa's Eagle 6.4 introduced an interface to link schematics with LTSpice IV for simulation. Unfortunately, the link does not seem to be fully functional. There is no documentation from Cadsoftusa about this link that I have been able to find. Cadsoftusa's website points to Newark (Element 14) for technical support. Newark (Element 14) has a number of Eagle Webcasts but these have provided limited help. Also, their forum questions go un-answered. In fairness, Newark (Element 14) is in the business of selling, not providing implementation details of a product; they do provide LTSPice IV models and Eagle symbols and placement data for many components.

I have been able to create a link Eagle 6.4 to LTSpice IV but have not been able to transfer a schematic for simulation.


Separately, I have been able to download spice models and symbols and integrate them into LTSpice IV for simulation.

Separately, I have been able to download and integrate schematic symbols and placement data into Eagle 6.4.

Getting the two products to work an play together seem to be problematic.

The Question: Has anyone in the forum had any experience with using the Eagle 6.4 link to LTSpice IV and can provide any guidance or point to potential information.

Using a link like this seems to be a good idea and I would like to take advantage of it. I'll keep trying different things as time permits.
