Hi, gEDA is a fine EDA tool set. PCB is a great stand alone PCB layout tool that includes an autorouter. Agreed. However, if you are going to use the PCB autorouter you must use PCB for your PCB layout. For example, how does one get their PCB layout into PCB to use its autorouter if you uses KiCAD, FreePCB, or Eagle? There is no interchange standard AFAIK. I think we've lost focus on the original topic of this thread so I will repeat it. If you are a software developer with familiarity with EDA and are able to help develop a truly free/open source PCB autorouter this is a great opportunity to help the hobbyist EDA community. This is desperately needed IMO. Hobbyist PCB autorouters are either non-free or lack support of interchange standards. QAutorouter has promise to open up free/open source PCB autorouting to all the hobbyist EDA toolsets that support Specctra DSN export and SES import such as KiCAD, gEDA, FreePCB, and Eagle. Please consider. Thanks and have a nice day! Andrew Lynch -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, I'm working on a project here http://sourceforge.net/projects/qautorouter/ It is an auto-router that is written in C++ on Qt application framework, reads/writes specctra file format and uses a plug-in style of interface for the router engines. It is very alpha at this stage, I have much of the UI, file I/O, and the plug-in API operational. I am working on a "Simple Router" plug-in at the moment that is implementing a simplified version of the expanding box algorithm. The Simple Router will be used as a sort of template for debugging the plugin-api and as a template for developing more sophisticated plug-ins. Toporouter would be a good one. In any case, it would be great to get a few other people on-board, a developer or two that is quite proficient in C++ would be very helpful, some hands-on with Qt would help a lot too. Someone to look after the Windows(tm) and Mac OS-X build and release would be very helpful. Someone to help with packaging; windows installer, Mac OSX installer, and linux .deb, .rpm packages would be helpful as well. If you're interested, please just send me a little about what you can contribute, and your sourceforge id. Kind Regards, Mike Sharkey
