Let me add my input as a professional (does-it-for-a-living) EE with nearly 30 years of experience. (Holy moly! How did that happen?) Regarding integrating any kind of simulation tool into the mainline PCB design package, I suggest the following: DON’T BOTHER. Why? Because board design and circuit simulation are two different processes with different goals. Altium offers it, nobody uses it. The problem is that the things that you need to do a proper simulation are not relevant to layout. Assuming a SPICE engine, you need the simulation control cards, you need models for everything, and you need the stimulus. And then there are the things that you need to make a functioning circuit board that you can’t simulate. So you have to work out how to make things like connectors and such vanish from the simulation netlist, and you need to do the same for the stimulus sources and such from the layout netlist. Perhaps someone can explain how to use SPICE to simulate only the DAC output reconstruction filter or a mic preamp that is integrated in a design with the converters and a processor and other stuff, then maybe we can have this discussion. And further: the world really doesn’t need another SPICE simulator. Every professional I know uses the free (as in beer) LTSpice. It runs on Windows, Macs and Linux. You can add third-party models. It really just does work. Is it Open Source? No. Does that matter? Only if you’re Richard Stallman. The rest of us have work to do. (There’s another free alternative for OS X users in MacSpice, which doesn’t have its own schematic editor.) What do I want? A robust PCB design package that can handle designs of any complexity and specialist design rules. Integrating a VHDL or SPICE simulator gets in the way of that. (Again, Altium: it has all of that extra crap that nobody uses and the users complain about bugs that go unfixed for years while Altium adds an 8051 compiler.) Regarding usability: Yes, of course usability is important. But who should determine how the user interface should be implemented? My vote is that people who’ve spent years in the trenches of board design are those whose ideas you want to capture. Sorry, newbies to PCB layout don’t get to tell the vets how the program should work. Harsh? Sure. My pals in the live sound business call it the Anvil Of Reality. There’s always some kid who thinks he can step up to a rig in a theatre and mix a show without having the experience of working the clubs. They always get told “no,” because the kids don’t know what they don’t know. The other topics have been covered by Wayne and others. -a _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
