It seems very great, but I dont know the syntax for measuring the network parameters! (Z(11) or Z11 or ...)

Hello,

If you have .measure commands in your schematic or your netlist,
you will have their results in the log-file.

Best regards,
Helmut

Hello,

Ltspice writes a file named design_name.txt when you export.
Please do exactly what I said in my last email.

Files -> Export

Thanks in real, of you and also of the others for your and their guidance.

Thanks a lot, so, you say that the results of .Net analysis are adequately accompany the *.raw file? Am I right?
(I am wondered that when I change output format to ascii, there is no network analysis data!)

I have not performed a .net analysis, but whatever LTspice saves
to display in the waveform window goes into the .raw file, so
I assume that the .raw file contains the information you want.
I leave it up to you to investigate :)

Cheers,
Dave

Is there any body who obtained the results of the .Net
analysis directly from a text file without the help of
Waveform Viewer (just like HSPICE)?

Read the user manual entry for .save, i.e.,

Start LTspice, and select Help->Help Topics, then click
on LTspice IV, LTspice, Dot Commands, .SAVE

This limits what is saved into the .raw file. I then use
LTspice2Matlab to read the raw files. I posted an example
a few weeks back (look in the Yahoo groups files area
for it).

Cheers,
Dave

I, for one, didn't, but maybe you could ask Mike himself about this.

I also found that... but I don't know how to make it work on ltspice... the format is different.. Do you know how to make it work on ltspice??

Hi shadow,

Have you searched a little on internet ? I found that :

I also need an op27 op amp.. sorry for the double post... thank you..

Good day to all...

Do any of you guys have 1n4153 and 1n746a models for ltspice... I need to simulate a circuit using those 2 diode...

Any models? or similar diode models? Thanks..

Interesting! That is news to me. Thanks.

Q1) Would you tell me the method of ascertain the yahoo ID.

I can see that you used the Yahoo! ID of "hiromasashigematsu".when you
posted your earlier messages to the [LTspice] group. (We can see that
from the Message listing.) This should mean that "hiromasashigematsu"
is the one you used when you joined the [LTspice] group, so logging
into Yahoo with that Yahoo! ID SHOULD give you access to the [LTspice]
files.

If you have other Yahoo! IDs, they might or might not also be "signed
up" for the [LTspice] group (depending on whether you also joined this
group from those Yahoo! IDs too). You must use a Yahoo! ID that has
joined the [LTspice] group, because the group's files are accessible
only to members who have joined the group.

If you can see the files, but can't download them (as others have
suggested), then I don't know why. That is very strange.

Good luck!

You may want to try the other Yahoo group, "switchmode", they may have the answers you're looking for.

Hi,
i was thinking that the main component what i have used is of LT and so this group should be aiding me.

Thanks

Yoga,

You are missing a ground on the bottom half of your circuit. Here are some other comments:
1. You could 'clean up' your circuit by combining all the parallel caps and series resistors.
2. You don't need any caps in parallel with the DC voltage sources that have zero resistance.
3. Your current pulses aren't going to work right, because the sum of the various times exceeds the period.

Hello all of you,
I download:
NE555 (Tansistor leveltimer.asc from Files&#92;Files sorted by message&#92;msg_31483 ( NE555 transistorlevel/leveltimmmer.asc }
Why is V( out) or V(OUput) are going in strange frequencies ?
Thanks

Mike,

The -nowine switch is documented in the LTspice's help manual, see Modes of Operation > Command Line Switches:

"Prevent use of WINE(Linux) workarounds."

I don't know if this happens to all, but when using LTspice normally, that is, without any arguments passed on to command line, trying to resize, for example, the dialog window for adding a spice directive, will resize the perimeter without the contents of it (I hope I found the right words). If there are more than 4 or 5 lines of text, they will be hidden (but you can still scroll through).
Using -nowine will allow resizing the contents, too, so now you can have an entire novel and be able to see all the text.

The downside of this, of using -nowine, is that when you try to move a component (e.g. with F8), it will leave minor dots behind (at grid's spacing), traces of them like crumbles, which cumulate, but they are gone the instant you drop the symbol with the mouse-click, or when the viewpoint of the window changes (for example when you zoomed in and, when moving the symbol, the current view of the schematic shifts to adapt to your direction).

This isn't as bad as it seems, since moving components doesn't mean playing around with them, and there's an actually good indirect effect: suppose you want to copy a symbol and move it, symetrically, downwards or anywhere; the trail will let you know if you strayed from the path.

The custom launcher is used simply to tell WINE that I want to use the INI from the LTspice's directory (custom installation, models, etc) and to add the -nowine switch. The clean installation is in a different location and uses the %AppData% from Windows.

This is about as best an explanation I can come up with right now.


Good luck understanding,
Vlad :)

Mike,

The new .ini location follows the Windows' one:

/home/<user>/.wine/drive_c/users/<user>/Application Data/.

Personally, I run the clean version the way the installer made the launcher, and the custom version like this:

env WINEPREFIX="/home/<user>/.wine" wine Z:&#92;&#92;opt&#92;&#92;Progs&#92;&#92;LTspiceIV&#92;&#92;scad3.exe -nowine -ini Z:&#92;&#92;opt&#92;&#92;Progs&#92;&#92;LTspiceIV&#92;&#92;scad3.INI

( -nowine because I can resize the components' dialogs, with the downfall of traces when moving symbols -- minor)

Vlad

Vlad,

Thanks for the reply. I wonder what the option "-nowine" does. I tried google and visited pages like

"
"
"

But I cannot find that option anywhere. Do you have a link you can post?

I also wonder why you use your custom launcher, and what do you mean by "downfall of traces when moving symbols"?

Thanks,

Mike

Hi RainbowSally!

Wow, you weren't kidding. OMIGOD, you should have seen the circuit I came up with while you were redoing the first one...somehow I got the notion in my head I needed to use peak detecting op amp circuits to define the top and bottom of the sawtooth, so I had both positive and negative peak detectors feeding a potentiometer going to a comparator....

....your circuit was a marvel of sophisticated elegance, I can't thank you enough.

I would post my new version of your re-do, but...I'm still waiting for LTspice to find an operating point LOL!!!

I'm going to bed now. If, in the morning, it gave an error (time-step error most likely; I think that's when it can't converge?), I'll post it asking for help getting it to run, and we can talk about design at the same time.

However, if it does finally run, then I have no reason to post it here; it would be off-topic to discuss the design elements (I've added a new section you haven't seen yet that's the point of the 1st circuit) - so am wondering where you'd like to continue the discussion...electronics_101? funwithtransistors? (both yahoo groups).

Very Best, with gratitude for your help, Maturin..errr, Gandolf LOL
