I have just spent a few hours playing around with the ngspice Simulator in KiCad 7. I am already a fan. Some very initial impressions... Positive The UI, starting from the same schematic entry tool as KiCad uses, is a winner. There is no comparison at all with LTSpice's UI, which is frankly awful. Fairly short learning curve if you come (as I do) from an LTSpice background Much easier process to integrate third-party models (again, in comparison to LTSpice). I had some potentially show-stopping questions that I was able to resolve by experimenting with the UI and finding how it worked SPICE_LIB_DIR - thank goodness for this Was able to import models from Texas Instruments, Infineon, ONSEMI... and have them actually work in simulations without a fight. Winner. Simulation UI is pretty simple and straightforward for this stage of development. And it does work! Things generally 'do what you expect' - a plus. 'Workbook' concept is nice 'Tune' tool, using a slider to manipulate a simulation component's value, is an absolute winner. What a great tool. Lots and lots of potential here. I went in cold, but will be using this a lot more. Great work KiCad team! Negative A few niggles with the UI; some small fonts that cannot be read easily Wishes So many, but I fully understand this tool is a work-in-progress (and as I said, great work so far) Would like the ability to place Operating Point labels on the schematic (LTSpice .op directive) Rename/label 'signals'? Cursors, measurement tools etc. Again, a huge amount of potential, great tool, I am a fan thanks just to a short time experimenting.

Hi, I'm Alessandro, new member of the group. I come from Italy, and to write this message I was helped by the automatic Google translator. I have been using KiCad for some years both for personal purposes and for work. I have a question: I'm finishing making a medium-sized pcb, in the shape of a circular crown of about 30cm in diameter, for a led lamp. The problem is to arrange the thermal connection vias (about 1000) between the two layers of copper (top and bottom). I created a circular array of vias (arranged on three circumferences), but I had to edit (almost) individually the parameters (in particular the connection NET). Is there a faster (automatic) way to create arrays of vias in cases like this? And possibly there is also a way to create circular shaped copper zones? At the moment I have solved it by inserting circumferences in the "margin layer", keepout zones and using different priorities for the various copper zones (a job that took me several hours). I hope there are more efficient methods than the one I've used, especially since I may have to do similar jobs in the future... and I don't want to go crazy like this time. Is there anyone who can give me advice please? Thanks in advance with hope, in turn, that i can be of help to someone. Alessandro

Why not just try it?

I am still using Kicad 3, I build many small pcb’s that are small (less than 1 square inch) that have no components just two holes. I panelize them the hard way, by placing each on the grid, since I either cut them out by punching or have the shop rout to the OD line around each part. I don’t want to use V score or break apart since I need a vary clean edge. Is there a spell and repeat command in a newer version of Kicad? I used to work in a pcb shop in the 1970’s and did panelization on a light table and grid! Thanks, Greg On May 21, 2023, at 5:06 AM, John Woodgate <jmw@...> wrote: ? I found out how to do it.

As in topic, I did a fresh install of 7.02 on a win10 fresh install. I can import my old board designs fine. Schematic crashes every time. CPU load goes way high, need to kill with task manager, red "X" doesn't work, get a "not responding", the "wait" circle stays on screen. Anyone have any idea what I need to look for that is making kicad unhappy? GeorgeC

I've used KiCad before, but it was a few years ago and I never got that familiar with it. I have a new project, so I'm looking for a fresh start. I thought I should update to the latest revision, which seems to be 7.0.2, running under Windows 10. I guess I'm used to software that knows how to check the rev number and update itself. But it appears KiCad doesn't do this? Or am I simply not finding the button to tell it to check for updates? So I need to download the 7.0.2 revision and install it over 7.0.0? Also, my vision has taken a turn for the worse since I last used the tool. Like many Windows programs, they aren't very good at letting you specify the size of various text. I don't expect the schematic or layout to be a problem because you can zoom in on what you want to see. But the text in dialog boxes and menus is very hard for me to read. I don't see any settings to help with this. Any suggestions? I've already zoomed using the Windows controls as much as practical. I'd prefer not to have to muck with that further. -- Rick Collins - Get 1,000 miles of free Supercharging - Tesla referral code - https://ts.la/richard11209

The following pertains to KiCad availability on Fedora Linux. Please note that none of what follows affects the official builds hosted by Fedora in any way. Everything below pertains only to the Copr repositories hosted by the KiCad team itself. Previously, there was only one Copr repository for KiCad [1]. It contained both nightly builds of the development branch of KiCad and released builds of the stable branch of KiCad. That arrangement turned out to be too limiting, because one might want to enable the repo to get nightly development builds, but might not want to get released builds from it. Additionally, the team wanted to make testing builds of the stable branch available, and adding a third thing to the repository would compound the problem. Thus, the stable builds have been split off into a separate repository [2]. *IMPORTANT:* If you were previously getting your stable builds from [1], you *must* switch to [2], because no further stable builds will be added to [1]. To enable the new repository, simply issue the following command: dnf copr enable @kicad/kicad-stable The new testing builds of the stable branch are available in [3] and can be enabled by the following command: dnf copr enable @kicad/kicad-testing A few things to be aware of: The builds in [2] and [3] share a namespace. If both repositories are enabled at the same time, they will effectively be combined; the build you get will always be the newest one available in either of the two repositories. In other words, if you enable both [2] and [3], a newer stable build will replace an older testing build, and a newer testing build will replace an older stable build. The nightly development builds in [1] are completely independent of [2] and [3]. They live in a separate namespace, meaning that you can have both a nightly development build and a stable (or testing) build installed at the same time.

Is it possible to capture a Spice schematic (perhaps in the form of an .ASC, .JPG or .BMP) as a Kicad schematic?

I have a design which is essentially two separate circuits (a motherboard and daughter card) with two 3.3V rails (+3V3 and +3.3VP) and two separate grounds (GND and GND1). They do, however, use two instances of an ATMEGA808. The ATMEGA has Vdd and Vss power pints. When I update the symbol of the ATMEGA808 The schematic editor will alternately merge +3V3 and +3.3VP or GND and GND1. I do not know if this is a bug or if I am doing something wrong. Thanks

Selecting of a locked part does not work in 6.0.10. So how can I unlock it ? Thanks, Axel --- PGP-Key: CDE74120 ? mobile: +49 160 7568212 computing @ chaos claudius

Hi all, I have 2 boards with 2 pin headers and pin aockets, which should plug together. How can I transfer the position of the connectors from one layout to the other one? Last ressort would be to manually place them with the measure tool. Any help welcome, Axel --- PGP-Key: CDE74120 ? mobile: +49 160 7568212 computing @ chaos claudius
