Re: Great Movie Line from an Old Bob Hope Movie

I agree entirely. And the free and generous support of the head developer on this group - thought it can't of course be taken for granted - is another bloody good reason to look no further.

I can't help you with the crack, but if you want to use a free, open-source schematic capture and layout package, why not use gEDA:

One of its main features is that *all* file formats are cleartext ASCII. That way, you're never locked in to any vendor's proprietary format. Later, if you want to use a different tool, conversion would be a piece of cake.

FWIW: you can create layout netlists for Protel & other commercial tools from a gEDA/gschem schematic using currently-implemted functions, so you are already afforded a lot of options with the gEDA suite.

Happily, (as you will know!) One can simply use exponents instead, for the avoidance of doubt.

This is not really an accurate description. XSpice *is* already the combined Berkeley spice with Xtensions that add digital capabilities. That is, there is not a separate Georgia Tech digital engine that was combined with a separate Berkeley spice. XSpice is not a "digital simulator". It is a mixed mode simulater.

As can any generic spice, so its not.

This is not specific to Sabre at all. *Any* and all spices have behavial modelling, e.g. B sources that allows pretty much any function to be implemented. In fact, spices like isspice have full scripting with constructs such as if else.

?

What aspects are you refering to here? Obviously, I will take this opertunity to point out that SuperSpice has quite a few i.c. specific hooks directly built in, such as mosfet binning, and automatic worst case reruns. I am not aware of any in the "cheap" simulaters that do this.

SS is also set up that it can automatically drive any engine if it can run in standard spice batch mode.

Indeed. Mine is that SuperSpice has the best GUI in the known 3 universes.

Hi My daughter would like to use "Stripboard Magic" for some upcoming course work but I have lost my copy. I have tried searching on the net but to no avail so if anyone could tell me where I can get a copy I would be obliged.

Thanks S.T.

Hi,

Does anyone know how to import a Protel schematic into OrCAD?

Thanks!

Thanks for the link Geo. Its a shame the company went down the program is a god send to hobbiest people.

Thanks everyone S.T.

If it could only read netlists from other programs. It would be nice to have, say, parts of a larger project quickly placed on a veroboard to do some testing on the labtop before sending the stuff to production.

And there are many different types of veroboards out there, would be nice to be able to autoplace and autoroute a couple of those.

SBM is also a bit tricky to work with, specially when you are used to other EDA programs.

Vutrax has a procedure for laying out PCBs on Stripboard (Veroboard) on circuits derived from schematics or netlist. Available for Windows 95 through XP and Linux as an about 10MB download. It includes an interactive tutorial & practice system and is free up to 256 pins (surely enough for Stripboard), with many options thereafter.

There is a supplementary Software Advice Note (SAN 206) obtainable from the support section of the web sites, that outlines methods available for handling Stripboard with or without schematic entry.

Visit either of these for a look

Hello people

Is there any circuit simulator that can use dual processors, or is optimized for Pentium 4 with Hyper-Threading?

OK folks... This is probably a RYFM question, but...

I'm trying to use Multisim after about 4 years of not having done any circuit simulation.

I can't get a 555 relaxation oscillator to work, and I can't even simulate the charging of a capacitor. (Hook up a 12-volt source with negative side grounded, 1k resistor, 1uF capacitor, all in series... put the virtual oscilloscope on the high side of the capacitor... flip the switch... and it's at V+ all the time; we don't get to see it charge.)

I seem to recall something about having to tell it that the capacitors start out with zero charge. Is that right? What am I doing wrong?

Many thanks!

Got the answer (even though a quick look at the manual did not reveal it)...

You have to double-click on a wire and choose "Use IC [initial condition] for transient analysis" and set the wire to 0 volts, or whatever. Then Multisim will know the capacitor is supposed to charge. Otherwise it will find a dc equilibrium point and stay there, perfectly balanced, forever...

Now can someone tell me why Multisim 6.11 is giving so many "Memory error" pop-ups under Windows XP? Admittedly this is not the latest release of Multisim...

Useful suggestion. Thanks!

In Win98/Me mode, it can't see its dongle. In Win2000 mode, it runs, and time will tell whether this helps with the memory problem. There is also an NT4 compatibility mode.

I do wonder how much difference there could be between Win2000 and WinXP!

Try using it in Windows 95/98 compatibility mode.

Windows XP, AFAIK, is just the nice graphical themes, over Win 2000, and some networking utilities removed. Since I rarely use XP (I am a Win 98 user for mantaining old hardware)...
