Isn't this what a Net-Tie is used for in KiCad?

I'm not yet skilled enough in KiCad to know of that feature. Thanks for the tip.

This is an absolutely vital feature for what I'm now doing. I design
induction heater boards for my friend's company (fluxeon.com). On one
end of the board is the 3.3 volt processor and analog electronics
necessary to protect the SiC FETs on a cycle by cycle basis. On the
other end is a 10kW Royer-type power oscillator. I must tie GND and
PGND (power ground) together at one point.

4 layer board. The outside lower layer is PGND and the inner ground
layer is GND. In Eagle where I'm coming from, to tie the two together,
I simply lay down 10 vias in two rows of 5 as close together as my board
house can handle. On the bottom layer, the solder mask is manually
opened up in the software so that paste is applied across all 10 holes.
When reflowed, a continuous solder blob covers all 10 holes and fills
them with solder. There is no power flowing through this interconnect
but it has to be low impedance so the ground voltage will be the same on
both sides so, for example, the source current shunt low side will be at
the differential amp's ground. I use a differential op-amp for sensing
and for sensing the peak voltage across the FET but keeping the two
grounds at the same potential makes things more noise-resistant.

Isn't this what a Net-Tie is used for in KiCad?

My Rome, GA box builder is competitive with the chicoms until I add many
thru-hole devices to the board. A jumper would add cost to the board.
I run 50 boards as the pilot run and if everything works correctly, they
do a production run of 500.

I've been doing electronic design for decades and was an early
evangelist for open source. One guiding principle was and should be now
is that FOSS software is better than the nearest commercial equivalent.
Being able to connect two planes together directly in the software is vital.

I love this product and send money when I can so I'm an absolute
supporter of this project. Let's keep it the best out there.

I usually just use a jumper, or if there is a lot of power, a series of jumpers.

I don't want to sound too critical, but didn't you check the Gerbers before sending them out for PCB manufacture?

Exactly what is the problem.

Kicad 5 can read kicad4 circuits with no problems

Dear Marco,

As Sumanto mentioned, we have been using KiCad for the eSim EDA tool for
several years. During these years, we made a library of ~1000 schematics
designed in KiCad's latest version (v4.0.7) at that time. So, to remain
consistent and portable with our circuits library, we continued using KiCad
4 based on this old version.

We take this opportunity to request your suggestions on feasible ways to
port these circuit schematics to KiCad 5 or 6.

Why are you trying to install KiCad 4? It is way old! Even what comes
with your distribution (that is usually not so up to date) is newer!
Install KiCad 6!

While this mode of usage will not be a priority - because slightly exotic - the question is: Is this a *known* problem? Should we file a bug report?

I don't know if it is a KiCad problem, a video card problem, or something else in the rendering stack. VNC works well enough for my use-case. I mostly just run KiCad natively on my desktop, and only need remote access when testing new builds on headless machines. For example, I test Fedora aarch64 builds on a headless Raspberry Pi running a pre-release of Fedora 37.

My solution has been to connect to the hosting machine via VNC.? That

Yeah, we are using this solution too ATM. But it is far from ideal, because the desktop size is fixed and the whole solution is slow compared to X-forwarding. But it works for now.

Greetings all!

Unfortunately, not answering your question, but I tend to run old
software in a VM with an old OS, and run the actual machine with a
new, up to date OS with recent security fixes. If you back up the VM,
even if it is compromised, you can restore it and keep going. It
lowers your risk of having an old, unpatched OS exposed.

I am working on a solution for this problem, as it annoys the heck out of me. I don't like having to work with an old OS one bit - not only for the reasons you have already mentioned.

The "industry standard" software we use is still specified to run on a Red Hat 7, I believe. If it detects anything newer, it refuses to run. We have taken steps to use newer distros and to "mask" the actual OS. We got stuck when the NICs got renamed from eth0, eth1 to whatever they are called this week. The software is "dongled" to the network card in the work stations. I have not managed to pass the "dongle" through a VM thus far - at least not in a way that lets everything work.

Things are going to get really dicey next year, when we plan to buy new work stations. I am going to have to get really creative then, because I don't see any older Linux distro running on the new hardware.

I've run Kicad in a container. Is that possible on your older OS?

Haven't tried that yet. Might give it a go in the future.

Cheers!
Chris

Hello dear readers!
We are currently checking out Kicad in our company. We are a small engineering firm.
Because we have to use pay-soft on a regular basis (there is no OpenSource alternative that is supported yet), we have to run our workstations on a pretty old Linux distro. So we can use current software, I have set up two machines with current distros (OpenSuse Tumbleweed) and we can connect to these via ssh. This is just to answer the question "Why would you want to use Kicad remotely." :-)
Kicad via ssh worked fine until recently, when I started a system update (zypper -dup). Tumbleweed is the rolling release, so there is no real version number. We did however upgrade to the Kernek 6.0.5-1 (from a 5.x Kernel). I'll put the other (Kicad) info in the footer. If you'd like more system info, please let me know. I don't want to throw a gig of info into this mail on a whim. :-)
Now, Kicad starts fine and I can browse projects and everything. However, when I actually open a project (even a demo project), I get a brief flash of the editor (at best) and a rather short error message:
fish: Job 4, 'kicad' terminated by signal SIGTRAP (Trace or breakpoint trap)
I have not found any way to make Kicad be a little more verbose about this (-vv or such is interpreted as a filename). There is no other output to the shell from Kicad.
This only applies to Kicad started remotely. When I start Kicad locally, everything seems to work fine. I haven't used it extensively locally, because the machine in question only has a rather old and crappy monitor connected that is good enough for testing stuff, but not really anything else.
We have run into a similar looking problem with different software before. This software tried to access the graphics hardware directly and had to be told not to do that explicitly before remote access worked (again). I don't know if these issues are actually related, but I thought, I'd just throw the idea out there.
Does anyone have an idea, what I can do about this?
Thanks for reading!
