"MARTHA" RF/Microwave CAD Using APL -- Free!
I suspect a lot of these old and free PCB CAD packages are not taking
full advantage of the current PC hardware. PC's have bags of memory now so the old pin limited packages are out of date. Things like vast processing power can be done to do things like auto placing of components. In my software I also added right click context menus which are very user friendly. www.murtonpikesystems.co.uk |

... I suspect a lot of these old and free PCB CAD packages are not taking full advantage of the current PC hardware. Possibly true, although I can comment that "PCB Artist" which is the free PCB package Advanced Circuits has wouldn't fall into that category: It's really a version of EasyPC (from Number One Systems / WestDev) in disguise, and quite sophisticated. PC's have bags of memory now so the old pin limited packages are out of date. Pin limiting has, in the past decade or so, always been a means of artificially restricting users based on how much they were willing to pay for a license and has nothing to do with not taking advantage of the hardware. Things like vast processing power can be done to do things like auto placing of components. I've yet to see an auto-placer that's worth using, but I'd admit that I haven't used yours. In my software I also added right click context menus which are very user friendly. Most Windows software did this around 1995-2000... (Of course, there's still overpriced stuff like PADS out there that TO THIS VERY DAY cannot be installed in a directory that has a space in its names... like, oh, say, c:\program files...) ---Joel |

PC's have bags of memory now so the old pin limited packages are out of date. Some of the free packages are based around DOS or early windows where a megabyte of memory was the limiting factor. Anyone who has put the effort into writing a "full" PCB software package is not going to give it away. It just doesnt make sense, they would be better off pulling pints at the local pub to make money. The pin limitation was used to offer cheaper packages to people but even some of the larger packages I have seen have limitations on them. I think my software tops out at 32000 pins per package which is an IC I am eager to see ! In fact you run out of room on the 50 inches by 50 inches layour before you run out of memory ! |

This is true, but from an *end user* perspective something like what ExpressPCB and Advanced Circuits does might as well be the next best thing to free: They create or license reasonably full PCB software (especially in the case of Advanced Circuits) and presumably pay for it off of profits made from fabricating the boards... which ends up being much cheaper (really, probably no more than a few dollars per design) for a hobbyist who isn't cranking out dozens of PCB designs every year and doesn't have particularly high-end requirements. |
