Re: Schematic drawing issues
IMO, it is odd that Stretching the rectangle's corner marker is ineffective.? It must involve drawing a lasso around it first, or nothing happens.? That is not intuitive.? Consider improving this.

Raise your hand if you feel changing hotkeys was anything short of a dumb idea. It's been said before too. Andy

¡°Drag¡± is now ¡°Stretch¡±, hence the ¡°S¡±. Raise your hand if you felt there is enough distinction between the words ¡°Drag¡± and ¡°Move¡±. Feels like one is simply a more specific

Re: Schematic drawing issues
As someone who has to often ask for schematics, I wish that this was the case. :-) Actually, when you create any Engineer Zone post with LTspice as the product, as soon as you click Post, a pop-up

Re: LTspice vs ngspice 12AU7 tube amplifier transient analysis
From the fact that the MNA system is based on node voltages as unknowns (including currents for voltage sources) and there exists the .NODESET directive for node voltages to aid NR convergence, I

Re: LTspice vs ngspice 12AU7 tube amplifier transient analysis
Not being intimately familiar with the inner workings, I can not confirm anything. But I will agree with the assumption that the initial guess about every node voltage - except for those actually

Re: Schematic drawing issues
So I tried. You can't use the word 'schematic' in a question without uploading a schematic! This is not sensible. I worked round it by writing 'circuit diagram' instead. Three cheers for British

Re: Schematic drawing issues
It is black if the background is set to white, as I have it, but the default background is black. The white dots are no more visible. How do I ask ADI to consider a larger dot option, or a grid

Re: Schematic drawing issues
No there isn't, but there is an option to set the dot colour, but I think the default is black, anyway. -- Regards, Tony

Re: Schematic drawing issues
I thought there was an option to change the dot size, but maybe there isn't. Don't have a copy handy to check at the moment. [email protected]> wrote:

Re: LTspice vs ngspice 12AU7 tube amplifier transient analysis
I'd like to ask how Newton-Raphson iterations actually work in SPICE/LTspice. I'm aware of SPICE uses, whenever possible, voltage-controlled representation of devices' I/V characteristic, i.e. the

Hi Tony, Thanks for providing this case. In a nicely condensed form, it demonstrates the problems of legacy LTspice and how they are addressed by 24.1. You have two models: .model 0 AKO: BSP89 .model
