Re: LTspice XVII under macOS (mojave) still broken in dark mode
Hello Andy,
> At some point in the past few years, I think Mike said LTspice in the
future will look more like the MAC version, without menu and toolbars.
I think Mike will never do that, because he knows that thr users of LTspiceXVII like the many icons.? The GUI of the MAC version is a bad compromise to keep the source code simple.
Best regards, Helmut

At some point in the past few years, I think Mike said LTspice in the future will look more like the MAC version, without menu and toolbars.? I guess he thinks it is easier to use it that way.

Hello Christoph,

I estimate this will never happen.

Re: LTspice XVII under macOS (mojave) still broken in dark mode
Hi Helmut,? believe it or not, I¡®m doing so for long?(wine version) Not only because ?of said bug but also since
I like the Windows implementation better for the tools being in better reach (toolbar) etc.
I would hope the Mac version would adopt the old proven UI some time in the upcoming versions.
Best Christoph?

Hello Christoph,
Maybe you could/should use the Windows version of LTspiceXVII with WINE on your MAC. This version doesn't have this problem in dark mode.
Best regards, Helmut

Thanks Helmut for delivering this important data point showing that I¡¯m not alone :)

Hello Christoph,
I can confirm your finding. When in dark mode, the "Add component" dialog window shows white text on a white area. This makes it unreadable.

Do you already have the model of the XL6009?
If not, the first step is to see if the manufacturer has one.
When you have the model file, put it in the same folder as your
.ASC file. Do not try to put it in an LTspice native folder
within Program Files.

Hey Guys,
This is Anuj Gupta from India, I am new to LTspice
& I am designing a tube light for that I need to
simulate my design but I am unable to a voltage
converter(which is required in my design)
How do I add XL6009 to the lib of the LTspice?
Pls, help?
Thanks in Advance

Re: Creating IC Symbol for DIP100
ayushijthakkar asked:
? ? "Can I just create symbol using draw tool and assign pin/ports or do I need to develop library for this 100 pin IC and then simulate?" What you need is a SPICE model.? The symbol is just an icon that goes on a schematic; it is not the model.? In order to simulate, you actually don't need a symbol, but you do (always) need a SPICE model.
? ? "If I need to develop library , any suggestion on how can I do this?"
To look for a SPICE model, start with the IC's manufacturer.
I see that T.I. has a "TINA-TI Spice Model" online.? Inside that ZIP file, look for the *.lib files, which have the SPICE models.? There are at least three *.lib files.? I don't know what's the difference between them.? Fortunately they are not encrypted, so there is even a chance that they work in LTspice too.? I'm just guessing here, but I think it's unlikely that they have one model for the entire IC.? Maybe they have separate models for portions of it.? I count 44 separate subcircuits inside the .lib file.? Some subcircuits call others.? Good luck figuring it out.
T.I. also has an IBIS datasheet.? IBIS datasheets ("models") can be converted into SPICE models, but that process is not straight-forward.? IBIS datasheets represent the characteristics of only the I/O pins, and nothing else inside the IC.? They are for simulating the signals that go between this IC and other circuits external to the IC.? In this IBIS datasheet, most of the pins are "NC" which means T.I. did not bother to include them in the IBIS "model".
Do you know what you want to simulate?? Do you have specific signals to look at?? Do you want to simulate it just because you think you can?
If you are not already moderately familiar with LTspice (or with SPICE in general), this is probably not a good IC to start with.? It is a moderately complex IC.? I would not recommend that someone who is not already familiar with LTspice try to tackle such a complex IC as their first project.? That is a little like teaching someone how to fly by first strapping them into the seat of a fighter jet.
Regards, Andy

It likely depends on what exactly you want to simulate. LTspice is designed to simulate analog circuits (but can handle some digital logic), so simulating the motor phase drivers and the buck power supply converter shouldn't be too hard if you have a reasonable model for the chip (or create your own from the data sheet). Trying to add the SPI interface, and the processor driving it is likely not worthwhile. -- Richard Damon

Re: Creating IC Symbol for DIP100
Hello,
The DRV8301 has 56 pins, but nobody on earth woud simulate its complete function with SPICE.
There is a DRV8301model for TINA-TI. It has 5 pins. It simply contains a subcircuit for a 5pin output driver circuit.
Best regards, Helmut

Re: Strange character in error log - "¡ì"
in reply to: "Have you checked the primary ripple current of your output transformer?? It's a decade too high, because the primary inductance with only a few micro-Henry is far too low."
I checked the primary inductance of my device, measuring around 6uH. This is a special case transformer, with an air-core 6-turn winding about 4 inches in diameter.? It is the primary of a Tesla coil, so normal values are not expected. Later,

Re: Hilighting a voltage in schematics
Hello Dennis,
Thanks a lot to remember me too about this feature.
Best regards, Helmut

Re: Strange character in error log - "¡ì"
I edited the .lib file to replace the double curly braces with single curly braces, following your suggestion to remove the "questionable use of curly braces" messages.? The warning complaints went away and the circuit seems to perform as expected. Thanks,
Carl

Thanks. Will do so. In the meantime: can anyone running LTspiceXVII under macOS mojave in dark mode, confirm the described behaviour?
