Failure at "Edit Simulation Command"

 

Hello, everybody,
i am using version VXII(x64) from Nov 26 2018
With this version I have the problem that the data in the "Edit Simulation Command" window is always lost. The SPICE directive are displayed correctly in the design but not in the input mask. Does anyone have the same problem? Is there a solution?
 

When the simulation command begins with a semicolon (";"), then it is a Comment = ignored.? Therefore, attempting to edit it will show no data.? That's how it is supposed to be.

Save it with a dot (period) instead of a semicolon.

Andy

Do you happen to be using a macOS and the dark desktop theme? I found that the device chooser view has white characters on white background.
Do you see characters when you select the lines with the mouse arrow?

Yeah, you're right. But earlier (version. IV) the input mask worked without problems.
 

I use Win10 64Bit

Who is right?

Right about what?

Yeah, you're right. I know the different functions of "." and ";"? But earlier (version. IV) the input mask worked without problems.
 

? ? "But earlier (version. IV) the input mask worked without problems."

Technically there were problems with it in LTspice III and IV.? But not this problem; it handled this pretty well.

Yes.? The behavior changed in LTspice XVII.

"Yes.? The behavior changed in LTspice XVII."

Hello, Andy, do you see the same behavior as me? That the mask doesn't work properly? Or is it just a problem with my installation?

Hello,

The behavior of the "Edit simulation" window has changed form LTspiceIV to LTspiceXVII.

Let's assume you have the following simulation command in the schematic.
.tran 0 50u 0 50n
Now do a right-mouse-click on it to get the edit-window for this command.

LTspiceIV
The edit window starts in the TRAN-tab. You switch to AC and enter the parameters for AC. You can go back to TRAN and the oroginal values are still there.

LTspiceXVII
The edit window starts is in the TRAN-tab. You switch to AC. The paramters from .TRAN are useless moved into the AC-tab. After you corrected/entered the parameters in AC, the settings in .TRAN are destroyed.

The "bad" behavior of LTspiceXVII is intended by design. We asked the designer a few times in the past to implement it as in LTspiceIV but without success.

Best regards,
Helmut
 

reinhold.pieper, the thing I don't like about what LTspice XVII does with this window, is that it remembers the settings from the last Simulation Command you edited.? So if you change from .TRAN to .DC or .AC, they don't make sense and you have to change all the boxes.

I (and I think most of us) liked the way it was before.? But we are stuck with this new behavior -- unless enough people can convince Mike to change it.? If I remember right, he was already asked about it.? He pointed out that something was actually wrong before, and HE likes the way it works now.

Regards,
Andy

Here is how I "deal" with this madness.

I put all the possible simulation lines in a single group of lines. I comment out, using the semicolon or asterisk, the ones I don't need for the present simulation.? When I right mouse click on the block of simulation commands I immediately press the ESC key (Windows) and the unhelpful simulation dialog goes away and I have a simple text edit box.? Then I can comment out one and uncomment another and press enter.? This seems to always work.

The simulation dialog box is broken on many levels.? Many times I change something in that box and say OK but my changes are lost.? IMO I don't see how Mike can use this dialog in everyday work and like it.? He should publish is work flow that he uses so we can all learn how it is "supposed" to work.
