Re: Schematic drawing issues
That might be the problem. A drag operation shouldn't turn into a move operation. If a drag operation has been selected, a click anywhere on the edge of a rectangle should drag the edge

Re: Schematic drawing issues
I don't know if this was brought up...but I still can't see a schematic grid. I haven't been able to view the grid for many versions of LTspice. I use a light grey background but it doesn't seem to

Re: Schematic drawing issues
Yes, a click on a rectangles corner anchor does allow stretching directly, but the click target is so very small that often the user clicks on one of the sides instead and then the operation becomes a

Re: Issue with Nexperia BUK7S1R0-40H PET LTspice model
Hi There is a special model "BUK7xxxx-40H_LTspice.zip" that needs to be downloaded and used for the simulation in Fig. 13. There is a link in the app note that initiates a download. However, when the

I will try to ask manufacturer, thank you for help :)

Re: Issue with Nexperia BUK7S1R0-40H PET LTspice model
It's quite possible that the data sheet Figure 13 isn't based on the Spice model, but on measurements of actual devices? of superior, rather than average, performance. There is no way we can tell.

I uploadet screenshots of my simulation and appnote Figure /g/LTspice/files/Temp/BUK7S1R0-40H%20simulation.zip. Yes i am looking at figure 13, the thing that bothers me are the final

Re: Issue with Nexperia BUK7S1R0-40H PET LTspice model
Thanks, but you should not have uploaded.RAW? and .LOG file. Now, I suppose you are looking at Figure 13 in the data sheet. If not, what are you looking at. I see the current in the voltage source Vs

I put it in temp file as you said /g/LTspice/files/Temp/BUK7S1R0-40H%20output%20characteristics.zip i meant AP note AN90034 wich is also in the .zip

Also, which Application Note do you mean? The Nexperia web site lists several.

Re: Issue with Nexperia BUK7S1R0-40H PET LTspice model
We can't help much unless you let us see more of what you are doing. Upload your .ASC file AND all the other files required to run the simulation, but not .RAW? and .LOG files or pictures,? in a ZIP

Re: Schematic drawing issues
I am sorry.? In my waveform colour scheme, I used the resistor colour codes, but offset by 1.? Thus "Trace V(1)" was Black, "Trace V(2)" Brown, etc.? I had become completely accustomed to Black

Re: Schematic drawing issues
Yes, that's why I wrote 'near'. For colouring traces, there is no use for '0', so it comes in useful for '10', and the other two colours are fairly easy to generate in the Settings.

Re: Schematic drawing issues
IIRC, Black represents 0 on resistors. (Colour blind, but not _that_ colour blind!) My favourite R was Brn-Blk-Orn Donald.

Re: Schematic drawing issues
On older versions, that did not work.? Attempting to "Drag" (old name for "Stretch") the exact corner without drawing the lasso first,?would Move the whole rectangle. Andy

Re: Schematic drawing issues
Considered and done! Actually, no change needed, you can already do this by clicking an anchor, or node, or component¡ªno lasso required. Apologies for this oversight in my instructions. mike --
