Antonio, Terry, Steve Connor, Ken Herrick for before...
much thanks for your resposes to my questions.
My idea to stay with Microsim/OrCAD was indeed beeing able to share
simulation files with other coilers, as mentioned by Steve. I've
tried installing OrCad 10.0 demo. It would support a perhaps nice
new feature for coilers, by supporting real, nonlinear magnetics
iron cored transformers. But I met a serious problem: the
installation has a problem with the "Norton Internet Security
Firewall". If the firewall is active, you cannot use capture (=the
schematics editor), while on the other hand, the software seems
resorting to internet resources, if i.e. you try "help". This was
confirmed yesterday, when I met the Swiss OrCad representative at
electronic fair INELTEC. There might be a workaround for it, which
the representative affirmed to seek for. In addition, there is also
a considerable learning effort, to master the new surface of OrCad.
As is, in my view, the internet problem seems inacceptable, and I
resorted to old Microsim 8, in order to be able using my former
simulations. BTW: it can be installed on Win XP, without having
compatibility problems, despite it's age...
Microsim 8, as Terry confirmed, is yet good for most coiler needs.
I'm just a little unhappy about the rudimentary printout
possibilities, and about not beeing able to display useful grids in
the probe diagrams. Anybody having a better experience?
Of course. if doing sim's just for youself, as a "lone wolf", other
sim packages might be better or easier:
I've not yet tried Antonio's preferred, fast SwitcherCad, but
consider to do. Thanks Antonio.
Another nice tool was favoured by Ken Herrick, September 11th 2002 ,
titled "MicroSim's Pspice Student vs. SiMetrix Intro":
SiMetrix Intro, a free version, at http://www.newburytech.co.uk
which indeed seems easy to learn for "old dogs", I belong to (66).
Downloded it and tried today by doing the short tutorials - indeed
exciting! A drawback may be the limited componets library of only
170 elements in the intro version (don't yet know, if including
company supplied pspice models are supported by the intro version).
Considering the time effort setting up a schematic, net simulation
speed may be a little less predominant, if not performing strong
parametric studies. I "think" the exchange of simulations among
coilers would also be easy, by just sending schematics files with
extension *.sxsch, instead of microsim's *.sch. There may be another
problem with the program, not featuring PCB designs, which may make
it unattractive for the recent trend in DRSSTC design.
I'm sure, there are other alternative simulators.

SwitcherCad works just like ordinary SPICE. It has
models for standard op-amps, transistors, diodes etc.
as well as the Linear Tech proprietary chips, and you
can edit/define your own models.
We use it at work because we're too tight fisted to
buy a commercial SPICE package, and it meets our
simulation needs fine. IIRC, right clicking (or double
clicking) on the component opens a dialog that lets
you type in whatever L,C,R you want.
I have also tried it for Tesla coil simulations but I
tend to keep coming back to the Orcad (ex Microsim)
PSpice Student version. The reason being that most
coilers use it, which makes it easier to share
Another handy feature of SWCad is that it runs on
Linux under Wine. So it's a good choice if you have
opted out of Windows.
