freeware circuit simulator for Osx (Mac)

[bichela]

Many talk about a program called psud. Does this have a Mac OSX version? If not. I downloaded some programs that are not GUI. I would like to find a program that I can plop the parts onto the simuboard. (why not call it that it isn't a real board). of known values from the database of parts/ including tubes. and run it through. Some of the things that I would like to simiulate

voltage and current in points of the circuit
Signal gain/loss in amplification

Frequency response curves and audio input filter tweaking.

I don't have the qt librairies on my mac but... I do have them on my linux boxen that are often tied up with another person browsing Ebay.

I use psud2 on my macbook all the time. Just download wine for package and you can run psud.

Wine is definitely the cheapest route since you will not need another operating system...if other operating systems are available try VirtualBox which is free but the OS is not.

If you want to spend more money try VMWare fusion for Mac. It'll cost money but works well. I've used them all.

I've not tried psud w/ wine yet but that sounds promising, will have to give it a whirl.

the problem with any virtualization software, they are memory hogs. Try wine, see if it works, then start shelling out the $

Eagle works on osx CadSoft Online: EAGLE Layout Editor it's free too.

ALso you can download sun's virtual box witch is free and works better than whine.

I dowloaded the Eagle editor. find the tube libraries. and unforuntatly got totally lost figuring out how to set the values that I needed for calculations. Nor could I find a 3 secondary center tapped plate transformer in the library. Nor do I know how to edit symbols to create a transformer that has a 500VCT, 6.3V and 5V secondary windings with a 120 mains primary. Nor did I figure how to connect the objects together! Sure with a ruler and pencil that is easy but.... my pencils don't calculate and my eraser doesn't rock and roll

My Emac has a 1ghz G4 processor so neither Wine or Vmware would be any good under OSX 10.4.11

My Intel Linux boxen are 1.9ghz intel processors. I believe those are P4s but it has been so long since I reallly worked on the Linux hardware other than running aptitutude to update the debian software every few days.

I will be watching this thread for new ideas too. I have Qucs which looks pretty powerful but there are zero tube models for it and it does not use spice as the core so spice models won't work and as of the last update I got its ability to translate spice models is not adequate for anything but the simplest of spice models (no good for tubes).

I too could not figure out how to get Eagle to work with existing spice tube models. I have a power PC architecture so I can't use wine. So as of now I use LTspice and PSD under wine on a separate linux box and use a thumb drive to transfer the results to my iMac.

I haven't really tried virtual box and the like. I think I have a copy of NT around somewhere but I am not sure where it is and haven't had time to mess with it anyway.

Copy of nt ? WHAT, that is useless lol

ATleast use windows xp or 2000.

Eagle is so easy to use.

Use eagle on a windows xp box, connecting the objects is very VERY easy, just select the tool. If you need help just ask.

Eagle is not a circuit simulator.

Yes, I must have been confusing Eagle with another one that I tried. I don't remember what it was but it had about 5 or 6 tube models and they were all oddball radio tubes. There was supposedly a way to make your own symbols and connect them to spice sub circuits but I could never figure it out so I deleted it.

As to NT, on second thought it might have been XP-pro. Will have to look around and see if I can find the CD.

Another one I have is MI-sugar which looks like it might work if I can figure out the documentation on how to create symbols and work with subcircuits.
