Free schematic and pcb design programs

Hello to all of You!

I am planning to sink my teeth into a "electronics CAD suite" in a not so far away future. I have used ulticap and ultiboard back in the days they still were DOS appz, I even bought a 80387 copro for them ;-). Not necessary to say that the version I still own is a bit dated now.

What is important, as it is only a hobby (and I am Dutch ;-), is that it is free. Open source is preferred by me but not a demand. It is highly preferable that the suite can be used both in windows and Linux, though not a demand either. If not cross-platform, I prefer a windows program but it is fairly important that it will run in 98SE as the computer I have in my hobby room is very old, 98SE runs great on it (much faster that Xubuntu) but I expect it to be too old for XP or 2000. This does not mean that Linux-only is out of the question.

I have already done a lot of reading on the web and KiCad, which I have been looking at a couple of years ago (it contained too many bugs back then to be of interest to me) and the gEDA tools are of particular interest to me. Free, open source and KiCad is cross platform. gEDA is officially Linux only and I don't judge myself to have enough knowledge to make it run under windows (at several places I have read that theoretically can be build for windows, perhaps with Cygwin, anyway, I do not feel like doing that). Linux only would do as well though it is not preferable.

Furthermore I have found out that gEDAis much more flexible/powerfull but also more difficult to get into than KiCad. I do not mind having a steep learning curve as long as it is possible with some engagement by me. I will probably be using it for a long time so it is an investment.

I am not going to do very sophisticated things. What is of utmost important to me, and that is my main question, is that the suite is _reliable_. Every program contains bugs but how often do You stumble upon them when using these programs? Very important as well is that there are libraries with many, many parts in them and an easy way to add new components.

I bought the program "Frontdesigner" program from

it was not expensive and is a great tool. This company sells a schematic capture program and a pcb editor as well but they do not cooperate, for me, that is a reason not to buy them (judging from the quality of the Front plate design program, I think they might have suited my demands, this is however too big a short-coming). So that is something else that is important to me: I have to be able to enter the schematic and then use that to design the pcb (check connections a.s.f.). But I also want to able to draw a pcb without being obliged to use a schematic. It does not have to be KiCad or gEDA.

I would be very pleased if You would express Your thoughts/experience concerning the things I have been writing. I am especially curious when it comes to stability/reliability of the different programs, the level of sophistication is less important.

Thank You very much in advance! Yours sincerely, Rene

This is totally wrong and I wish people would stop spreading this lie.

gEDA is fully supported on ALL unix platforms (not just Linux - includes BSDs, Solaris, etc) AND on MacOS/X (via fink). It is partially supported on Windows (it works, there are some glitches we're working on).

I think that's true of any EDA program - more features means more learning. I have recently written some tutorials for PCB at least.

We try to fix bugs as they're encountered. We have a very active set of mailing lists. Plus, the tools have been used for many boards, including some very complex ones. I don't usually encounter any bugs doing my boards, and the ones that others encounter are rare and usually obscure (today's bug was about duplicate traces causing polygon clearance issues - but pcb normally doesn't let you create duplicate traces).

Get used to the idea that you'll need to create your own symbols and footprints. Even on the best EDA tools, you can't guarantee that the library is complete or accurate. My tutorials cover footprint creation (footprint creation is done in the board editor), and symbol creation uses the schematic editor. The user community has also supplied a wide range of tools to automate these.

PCB's library does have most of the standard footprints, though.

gEDA/pcb works both these ways.

Hello DJ Delorie,

First of all, thank You for replying. Apologies for spreading a lie, that was not my intention.

I think You might even leave out the word "EDA" ;-).

I am going to have a thorough look at them later.

That means that practically speaking, it can be considered stable (in my opinion) and that is what is very important to me.

Now that is what is important. If I choose some very modern or some obscure component, You won't hear me complaining that I have to make the footprint myself. But in a review of the program "Sprint editor", by the company I pasted the url of, I read that there were not many footprints in there, even many very common components.

That is good as well. I must admit that the gEDA tools look very attractive. I am curious what others have to say but it does sound like it will be worth the effort to dig deeper into it.

Thanks again! Yours sincerely, Rene

I might not be understanding what you mean here, but certainly most programs like you "route over the top of/slightly to the side of/way off of" existing trace and then have the option of removing the original trace when you finish?

The problem only occurs when one line is EXACTLY on top of the other, though. PCB doesn't allow those by default; you have to do it on purpose, by creating a new line elsewhere and moving it on top of the old one, lining up the end points. At that point, you have two traces that are identical in every way, so why would you do it anyway?

That's why I consider it a rare bug. In normal usage, you won't see it.

What's the status of a (semi-)auto router for the gEDA package??

I'm mostly interested in medium complexity boards. They are big enough that hand routing would be a pain but not so big or complicated that the super fancy/expensive routers would have any troubles.

I'm happy to do a lot of hand holding, but I'm not very good at full on manual routing. It seems as though I fall off some cliff when the board gets too complicated. Maybe I'm just not patient enough.

FreePCB can use LTspice netlists. The former is Free Software and the latter is freeware. Both can be used cross-platform (VM / WINE).

BTW, this group is archived and searchable:

Damn Small Linux? aLinux (nee Peanut Linux)? Feather Linux?

As DJ said, the key word is "supported".

It mostly works (meaning, it works, but doesn't always route to completion). We've got a student working on upgrading it this summer.

DJ Delorie inscribed thus:

I think that there may be a small problem with your tutorials !

I tried to follow "Building from Source" and seemed to keep coming back to the same point without finding out how !

Thanks.

Obviously, I haven't finished that part yet ;-)
