I've got an OLD copy of Electronic Workbench that jams up Windows 7
every time I use it. Is there a (preferably free or cheap) circuit
simulator that is somewhat similar to EWB that doesn't cob up the OS?

Yeah, I know SPICE does everything but it is a royal pain in the ass
to use and doesn't let me do quick and dirty simulations that don't
have to be down to the gnat's eyebrow.

Suggestions?

No surprise there. IMHO the last-known-good OS from MS is XP. Which is
why I am sticking to that.

LTSpice. Take the plunge, I did over 20 years ago. Before that I used
ECA224 which is (AFAIR) the predecessor of EWB. SPICE makes things so
much easier. For example, if you get stuck you can post the whole thing
here, someone could take a look, massage it a bit, and post a corrected
version back. With EWB you'd be on your own.

I'll third Joergs suggestion that you go for LTspice. I used EWB and
made the switch to LTspice a year or two ago. It's not that hard, and
as quick as EWB once you're up to speed. As a side benefit you can
post your schematic on SED if you do get stuck. (Also plenty of help
here when you run into the inevitable 'bump' on the learning curve.)

VMware is another option. Those options will even allow you to run
16-bit stuff from before 1990-- I have an assembler from 1986 that
runs fine under 64-bit Win 7.. it's about old enough to be a grandpa.
VMWare runs rather snappily even on a netbook-like computer (mobile
core 2 duo). You can even install DOS 6.22 if you really want.

Just for laughs I'm going to have to load up DOS and run Z80MU (it
doesn't run under XP-32- gives a stack overflow. Z80 CPM emulation
running under DOS in turn under a 64-bit modern O/S. Glorious. Three
hundred years ago you could have been burned at the stake for running
such code.

But runs _all_ my old stuff. Which is important to me since some SW is

That is no problem in LTSpice either. I just had a gizmo here with a
resistor where the value depended on a node voltage. Which depended on a
voltage source. Which depended on a formula in its value line. You can
even make stuff dance to the tunes of Led Zeppelin.

Run it in a VM. Either from within Windows or under Linux. Hell, at
that point you could run the Linux version.

It would be interesting as to why WB is causing that problem in the
first place?

I am not defending W7 however, It's very possible there is something
happening in W7 that is causing that app to be put on hold, like a
process priority setting for that app.

Some apps do not meter very well and could get in a dead lock, which
isn't really a locked up app but one that got caught up in a
unpredictable timing snag. The change on the OS also can make scheduling
items behave differently.. If there is some kind of kink in the way the
software was written when processing multiple threads? Then I think the
only recourse would be to play with the APP settings from W7.

If memory serves me, W7 has a capability setting you may want to play
with for WB. Also, work bench could be attempting to access some
hardware that may have gotten ported over from an old machine or OS?

I perhaps should have been more specific as to my application.

I have exactly 60 minutes the first day of class (which is coming up a
week from this coming Monday) to get 24 freshman students up to speed
on the simulation program. If I had a whole semester to teach Spice,
that would be an entirely different matter.

But it isn't the case. After that first hour, we are off to the races
and the kids need to have at LEAST a nodding acquaintance with the
software. AND some of the student machines (and the instructor
station) are running XP and some of them are running Win7. To boot,
ALL the student machines are loaded up with Deep Freeze which removes
ANYTHING that the students load onto their machines during class.
Don't ask me to take DF off; I fought IT all the way to mahogany row
and got shot down.

So, let me try again. Anybody got a suggestion for a simple, cheap,
easy to learn simulation program that doesn't need to be accurate to a
RCH, but a simple first-cut freshman oriented program that is an
INTRODUCTION to simulation.

THanks,

Jim

LTSpice is pretty much the only game in town if you want something
free that isn't too difficult to use. I've run it under Windows XP and
now run it under Windows 7. Stuff that I ran under Windows XP still
seems to run under Windows 7.

I'm going to stay with LTspice. You can set up some simple circits
for the kids to probe. (square wave into R/C's or something like
that.) Then they can muck about changing amplitudes, frequencies,
adding more R/C's. Have you tried it?

There's Falstad's circuit program online. Java applet. Schematic capture
and basic simulation. Crude, but works for resistors and LEDs. Sometimes
works for diodes, transistors and op-amps; simple simulators like these are
real easy to freak out. (As unstable as SPICE is, it makes one wonder that
anything works at all, and that SPICE works as well as it does, when it
does!)

There's also another online environment but I forget what it's called.

You have my sympathy. Herding cats and freshmen is difficult.

Try one of these. I haven't tried them, but they appear to be
something like what you want. I included some that only cover some
aspects of electronics, as it may be easier to divide and conquer with
a component simulator, instead of trying to teach with a duz-it-all
application. If these don't play, I still would suggest you use
LTSpice despite the learning curve:

LT Spice. 60 minutes should be enough to get people running sims of
simple R-L-C-transistor-opamp circuits, assuming they understand some
about electricity.

I can Spice a simple circuit, and get DC voltages and waveforms, in a
couple of minutes. I often use it for stuff like voltage dividers,
instead of a calculator.

What if the student's don't install it? can you get the admin to
install it?

ltspice is free of DRM (unless you count some of the bundled models)
installs fast and is relatively easy to use. the only thing I've seen
EWB do that ltspice doesn't is realtime simulation, with Ltspice the
only user input is the 'run' button.

else one of those java thingies, but they seem easy to crash.

Since you have to teach what is available (really, get them to install
LTSpice if you can), start with how to input a circuit. If EW has a
graphical interface teach the kids just enough to use it and save to
student provided medium (hope for a flash stick). That is about all there
is time for.

There is an XP mode download for Win7, get IT to install that on the Win7
machines. It should help the the win7 machines.

A virtualized application such as LTSPICE running from a USB drive
might do the trick. I've seen them, but have not attempted to
virtualize a new app.

This is one path:**
http://en.wikipedia.org/wiki/VMware_ThinApp

Would the school spring for a $5 flash drive per student? I imagine
you could get at least 4G at that price point.

You could set up examples etc. that would be available. AFAIUI, you
take a (preferably virgin) PC and install the app, and capture a
snapshot of everthing including registry etc. that is

** ouch- looks like they want $5K + for this!
Maybe the 60 day demo would work?



Of course this is the age of the cloud..

MIT worked up a kind of online SPICE that works fairly well despite
the limitations of an unnecessarily ugly GUI.

Hey, what about something like this if it would suit your needs:

http://www.falstad.com/circuit/e-index.html

Pretty slick! eg http://www.falstad.com/circuit/e-555saw.html

I have EWB 5.12 running on Win7 (x64)

The way to go:

- install EWB 5.12 on a Win98-system
- get it registered with your registration-details (name + sn)
- copy the complete program-directory including sub-directories from the
Win98-machine into "C:\Program Files (x86)" of your Win7-machine.
- create a shortcut to your newly created "WEWB32.EXE" on your desktop
- configure this shortcut to run im compatibility mode with win98
- the first time you start EWB it requires the original installation-CD in
your CD-drive.

I've tried a little circuit, ran it with function-generator and
oscilloscope, and it looks like everything works just fine.

To use the help-function you may need to download the legacy windows-help
wich is available from MS for download for activated Win7-installations.

Old thread I know, but just in case anyone else runs into this, I've gotten Electronic Workbench (5.1) working natively under Windows 7 64-bit. The program itself is 32-bit, but the installer is 16-bit, hence you can't install it in 64-bit Windows.

The trick was to first install it under Windows XP mode, on the virtual C drive in the same directory you want to put it on the real C drive. Once it's installed, copy the contents of that directory to the corresponding location on the real drive. Finally, open the registry editor in XP mode, export the key HKLM\SOFTWARE\Classes\Software\InteractiveImageTechnologiesLtd.\ElectronicsWorkbench\EEW01\installation, and then import that into the registry in Windows 7.

In hindsight, before doing the registry hack, EWB popped up a dialog box that the EWB CD had to be in the drive. Perhaps if I'd put it in the drive, it would have registered itself?

Another one dreging up old threads.

But really, you know what the solution really is ? Keep your old hardware and old software until the smoke comes out. I still got XP on one PC and it runs great. And even then I instyalled old programs on it, like Offfice 97 Pro, that runs like lightning on it. All the software does.

Only thing you need is AV software and to be careful. Use it fro what you need it for. buy newer PCs for the junk they got now, almost none of which I use.

now they are bitching about Tektronix scopes that run XP. First of all, there should not be an OS on a scope, and second of all, so it runs XP. Keep it offline and nobody will know except you. Perhaps the bean counteers who, in corporatre America will insist all this stuff go in to the trash for tax purposes (which means it cannot be sold it must be destroyed because of US tax code), but in most cases, just run it until it drops dead.

That reinds me to put my main backup on one of the SATA drives in me server for when it drops dead. Its EOL was in 200_, ummm, whatever.

Don't let them pull you along with a nose ring to get every update. you wouldn't believe how old some of my software is and it serves me well. And I have to learn enough new shit just to fix the junk that I really have no time nor inclination to learn new software.

Sorry Bill Gates.

And Windows 10 is free ? I'll pass. I own't even take if you pay me enougy money to buy the best hardware in the world to run it, know why ? Because I know what I got and it works.

You won't be doing any of those freshmen any favors by introducing them to any other simulator besides LTSpice. If they can't grok the basics in 60 minutes they are in the wrong classroom.
