Re: KiCad 8 Error while using demo project
Yes, I know that, and so does KiCad. It is displaying a banner on each window saying the "schematic is read only" and the "PCB is read only", yet it is still trying to autosave the files to those read

Re: ngspice linear AC simulation?
Hi Jean-Michel, You are correct. At least in KiCad 8, the simulation plot window for an AC simulation always shows a decade logarithmic frequency scale. The ngspice simulator executes the linear

Re: KiCad 8 Error while using demo project
There are no read-only projects but read-only directories. Copy the project into a folder of your own and the problem should disappear. Regards,Pedro Enviado desde Yahoo Mail con Android

Re: KiCad 8 Error while using demo project
The same error message reappeared shortly after I posted my previous message. I now suspect that KiCad may be trying to autosave the project into the read-only Program Files directory. It shouldn't do
KiCad 8 Error while using demo project
I have just installed Kicad 8 and was trying to use one of the demo projects to check out the new features. I thought this error message appeared when I was using the 3D Viewer, but I am not certain

Re: Ignore courtyard DRC and library update
I see yes, Some old versions did do this, but now running 8.00 and it's gone!

Re: Ignore courtyard DRC and library update
Hi, Courtyard is board side specific. So if you place anything to the other side, it will generate no error. The problem here is that there are components under each other on the same side. Lev

Re: Ignore courtyard DRC and library update
Yes, It would be nice if KiCAD could be set to ignore DRC errors for THT parts on the opposite side. With RF boards the connectors (thru hole) are routinely mounted behind the circuit (SMD) to get

ngspice linear AC simulation?
Until KiCAD 6 I was able to define a linear ngspice AC simulation by including a text .ac lin 101 100 1meg for simulating a linear frequency range from 100 Hz to 1 MHz with 101 samples/decade but

Re: KiCad 8.0 - Simple transformer simulation
Hah! Embarassing. Thank you very much Tony, you're quite right. You solved my problem. Much appreciated.

Re: Ignore courtyard DRC and library update
Thank you! I am aware that there are alternative solutions (or lets call them workarounds) available out there. But I was specifically asking here for a possible (or future) KiCAD integrated way

Re: Ignore courtyard DRC and library update
Most of the boards I design have similar constraints, usually multiple areas with different height limits, and on both sides of the board. Normally what I do is create graphical keep-out areas on the

Re: Ignore courtyard DRC and library update
I think you can make FreeCad to do these kind of collision detection. I usually do it manually though. Lev

Re: Ignore courtyard DRC and library update
Question in this context: Is there a way to define a "keepout area" below the LCD for components lower than a defined height? (i.e. to use the space for passives < 1mm bit not

Re: Ignore courtyard DRC and library update
1) I also have a board with an LCD. I simply made the courtyard around the connector. The courtyard does not have to represent the outline of the part, you can make it a dot if you want. 2) I haven't

Ignore courtyard DRC and library update
Hi all, Thanks for KiCad 8 I have two questions regarding KiCad 8.0 1. I have an LCD on my pcb, and have a large courtyard for it. Under my LCD, there are lot of other components. When I run the

Re: Minimum Track Width for Very Long Tracks
The project changed as various engineers reported concerns, both potential and actual. Instead of one huge board there are now four relatively small boards, two at the top and two at the bottom.

Re: Minimum Track Width for Very Long Tracks
I should also mention an extremely fast setup called SPI which is totally dependent of the slew of rise and falls of the signals, to make it work, typicaly src terminated as in the case of the
