Schematic/PCB Design for Linux? 132

Posted by Cliff from the for-future-hardware-manufacturers dept.
VanessaDannenberg asks: "Occasionally, I have been known to design the occasional circuit board. I've been using Eagle, but with the board size limit of 3x4 inches in the free version, and a $400 price tag to exceed this limit, it is time to consider a Free Open Source Software alternative. Not being a Linux programmer myself, I have checked into and ruled out gEDA, KiCAD, Electric, XCircuit, and a host of others as being too incomplete to replace Eagle. My requirements are pretty basic: Draw a schematic, make a board out of it, edit and autoroute it, export to Gerber, and do it all natively within Linux. So, with this in mind, what suggestions do you folks have?"

      I second that.

      If Eagle does what the submitter needs then $400 is not that bad.
      Professional packages can run in the $10s of thousands per seat.

      IMHO you need programmers that are also board designers to be able to support an OSS project that can come close to the level of functionality of a commercial package.

      This is a specialized product after all and I don't think much can be borrowed from elsewhere. Are there any fields that overlap with auto-router theory?

      • Are there any fields that overlap with auto-router theory?

        Seems to me it would fall under the general heading of Graph Theory, in which case yes, there are plenty of related fields, and anyone with even an AS in Comp Sci should understand the basic principles.

    • Scratch that. I don't think you can draw a schematic and PCB would autoroute it. But someone more knowledgeable might check this and make sure.
    • It looks like the poster is looking for a full schematic capture > PCB layout program similar to Orcad or Protel. PCB only does layout editing.

      As far as I know, nothing exists that isn't seriously buggy/lacking features. It's really the one application I use at work that keeps me on Windows (we use Protel SE).
      • As I recall, PCB could try to autoroute, but it never worked well for me.

        The poster's requirements suggest that he/she should just shell out the $400 for a real Eagle license.

        An alternative would be to get the PCP source code and start adding the needed functionality. That effort would reveal Eagle' price to be a real bargain.

    I'd try to feel sorry for you, but having just spent $775 to get the full-on Professional version of Eagle (with Linux and OS X licenses), I just can't muster any pity. I earn money by using Eagle. You can get a 100mm x 160mm, 4 layer version of Eagle for $125, as long as you aren't making a profit using it. If you are making a profit with it, either you can afford to upgrade to a for-profit version, or else you aren't charging enough for your work. You can also upgrade at any time with full credit for previous versions.

Consider either a) using the non-profit version or b) getting the for-profit version but not the autorouter - Eagle's is very good indeed (FAR better than Protel's, IMHO), but you'll almost always get better results hand-routing anyway.

Sure, nice things such as Mac OS X print drivers, inline spell checkers, common dialog boxes, and pretty widows are nice, but they are not necessary in the least. Installation is a breeze if you follow the steps in the readme. It is still the same "professional grade" as used in Linux and Windows!

    I think the simple answer is that there is no package available that meets the poster's needs. Those that are available at no cost (FOSS) don't have the ease of use and power that's requested. Eagle seems to be the only thing close to the price range. I haven't used it; I have used "pcb" with success. Its interface is a little funky, but not counter-intuitive. And it is under active development, with a user group list that sends me 20+ emails a day. In particular the requirement for autorouting presents a high barrier. It's a high-end feature, but not really necessary for simple boards. A human being will almost always come up with a better layout than a machine, and for analog boards, autorouting is useless, because the design rules cannot be taught to the machine. If, as some have surmised, the person who originated the inquiry is a woman, the sometimes harsh and dismissive tone of some posts on this topic leaves me no doubt as to why there seem to be so few women involved with Linux.

    problems: not for complex/high-speed designs (if u need BGA devices, matched-length traces/impedences, etc. you NEED high end tools like Altium's Protel DXP/Designer or OrCAD)

    What problems did u have with KiCAD? I've done several hobbyist designs in KiCAD and it has met all my needs. It takes a while to get used to its quirky UI,
    • Mod parent up! It took an AC to write one of the only constructive posts in this thread. Although I also actually paid for the full version of Eagle and consider it the best money I've ever spent, at least the above thread tried to give the guy a FOSS solution.

      For what it's worth, though, Eagle rocks! Another poster commented about the difficulty of cad software makers to maintaining parts libraries - I think the better question is the ease of making your own parts libraries in your chosen CAD softwar
  • I do a lot of EDA, mostly under Mentor Graphics PADS. It's quirky, it's buggy, but I find I'm used to it and I actually almost like it.

    But for whatever reason, our department seems to be unable to purchase a seat (license) for it that doesn't expire. Which means that my designs become uneditable unless our department mails Mentor a check every 12 months. It makes me sick.

    I really want there to be a good FOSS solution, and like the initial poster, I've found the existing products to be really inadequate. Som

      Huh?

      1) I don't recall the gEDA project promising anything. Please point
      out a specific instance of this? It has enabled many people to
      use EDA software that would otherwise be completely unobtainable.

    I've used it for some fairly complex multi-layer boards. I prefer to do the schematic on paper and manually route it, but autorouting is supported. One warning: some of the symbols are wrong. In particular, the (default) holes in the pads are too small for most resistors.

  • Express PCB is a decent program, and it auto routes for you. Freeware.
