Hello people.
Does someone here has a link for downloading the SIMetrix Intro 4.5 circuit
simulator?
I need to open some schematics created with it, and the version 5.0 only runs

Out of interest I tried simulating the original (symmetrical) circuit

with CircuitMaker. But after an hour or so I'm darned if I can get it
working. Typical error messages include:

Howdy folks
I am studying electronics engineering at college, although I have had many
years experience in point to point wiring.
I am new to pcb design etc, I want to design my own pcbs and either make or

I know they are in the purchased topspice:-)
They for my own use, e.g. at ft=300Mhz, 250V, 7W, 3pf makes for a good

I need to build inexpensive 20V 3A DC regulated power supply

Can someone email me a parts list and schematic and   parts layout.  I do

I know various iteration of this question have been asked before but
it's still a good thread to follow.
I personally have been using Protel for a few years and have been
quite happy with it. As much as I have read about it's instability

I've been looking hard.  I need a decent schematic and PCB package under
$1000.  Don't need autorouter or a zillion layers.  Do want back
annotation and ease of use.  I've downloaded a dozen demo packages.  The
software all seems to be written by people with exceptional eyesight, no

accents.......
I have occasionaly done contract schematic capture and PCB designs over the
years, but now I am seeing some  opportunities for even  more work, which I

Hi sci.electronics.cad!
I'm looking for a cheap/free VHDL-AMS simulator to help me educate myself
about the language.
Any pointers?

What do you think about the compatibility of Cadsoft Eagle when using
outside layouters who use other non-Cadsoft layout programs? Can you
share experiences?

Hi,
I don't know if this is the right place for this question but
does anybody knows a program (freeware & linux) which calculates
high frequency fields generated by metal electrodes and

In case anyone here is thinking of dealing with

bad news.

Does anyone out there have any experience with both protel and dxdesigner?
Any reason to use DsDesigner ( and PADS) rather then Protel?

I am trying to identify a component on a board , its identifier is ISR1 ,
unfortunately its had its part number scraped off
Its function is to convert 24vdc to 12vdc @ 2A also there is a similar
device that converts to 5vdc @ 2A , so i suspect its a dc - dc convertor

Hello Group,
Could someone please advise me on creating a spice3 output file
(through the unix format) which prints a given output with no spaces
or page breaks.  For example, I'm trying to determine the real and
