Yes, they have a lot of symbols for many CAD editors,
but the problem is that they only have footprints for
two CAD aplications, and OrCAD isn't one of them :(.
Nonetheless, you can always use the footprint editor,
as other said :). You can also import/convert
symbols/footprints from other editors, but I did not
stopped to see how this works.

I use Protel 99SE and it works great for me. The footprint and
schematic libraries are limitted but there are wizards for creating
footprints.

Some people also like Eagle and it looks like it has a good library base.

I use Eagle mostly and Cadstar or Pulsonix occasionally, personally I 
have grown to like Eagle, its a memory hog (most cad stuff are), it 
has bad graphics rendering or screen update, desptie these quirks, it 
is simple to use, creating componets/libraries are quite good, the 
auto router isnt that bad at all. It seems to be getting popular 
amongst the hobbyists mostly, I have not seen any big company 
providing their reference design schematics in Eagle but I see that 
TI's asking on its component footprint download page a survey on 
should TI provide Eagle format libraries. I guess its a matter of 
time ;)

Cheers

I start to use a free software call CIRCAD, I play very little with EAGLE last
year but I really start do something just now with CIRCAD.

any suggestion to  a free package with a good library for free?
There is http://www.geda.seul.org/ and pcb.sourceforge.net and
opencollector.org.

The library issue is always a problem. As I understood there's a movement
at 
IPC.org to create a free standard based on xml to provide components, footprints

etc. But this will last a bit until it hits the road, I guess. Meanwhile 
everybody and every company seems to write and maintain their own libs. Strange,

  work is duplicated very often. Why for e.g. component producers or 
distributors didn't cope with that earlier. Imagine a lib containing all 
components offered by farnell (index with their order numbers). Press the BOM 
(Bill of materials) button and send it off. That really would save a lot of 
time, wouldn't it?

Greets,

	Georg

Hi group.
I'm a hobbist user and I don't want to spend money for a package. I
start to use a free software call CIRCAD, I play very little with EAGLE last
year but I really start do something just now with CIRCAD.
Before getting too far with Circad (very poor library in the free version) any
suggestion to  a free package with a good library for free?
 
Regards Paolo.

Hi

I have  made good experience   with target  PCB and ASIC Layout-CAD/CAE
Software.
They have a great lib and also you can download a useful demo version.

http://www.ibfriedrich.com/english/index.htm

The software can import Eagle Lib files.

Maybe interesting  !

To all a nice day

You probably mean already released IPC-2581, successor of ODB++ and
GenCAM. If yes, then it is only for PCB CAD and CAM data exchange
(footprint libraries and manufacturing data). Not for schematic symbols.

See more here:
http://webstds.ipc.org/2581/2581.htm

Just because there are many different possibilities of using same
component. I often have several footprints for same component calculated
dependent on reliability and density classification of circuit component
is used in. Some clarification is brought to matters with upcoming
IPC-7351, successor of IPC-SM-782A.

Not much. For every bit larger project, every component used needs time
for verification which makes time spent on finding out order number
quite marginal. Usually places like Farnell, Digikey and ELFA are used
for prototype runs where purchasing whole reel of components is not
sensible, there are no components in stock and lead times for samples
from manufacturers are too long over regular distributors (AvNet,
Insight-Memec, Arrow).

Hi Paolo,

Through my uni days I used Proteus by Labcenter 
(www.labcenter.co.uk). This was ok for schematic capture and PCB 
layout (autoroute). It had a fair but not impresive library 
although creating parts was easy as most share a common 
footprint. One nice feature was the simulation facility. This was
based on a Spice engine but was not hugely accurate. Things have 
now changed!

You can now download Proteus VSM which enables you to do all of 
the original things but also simulate with a processor and 
peripherals. It can run C code in-line and spice analysis on the 
analogue parts with a good scope facility. One bad side is that 
the free version will not allow you to go from schematic to auto-
route. You must pay for this but you can input the parts 
straight into the layout package long hand (all the parts have 
definable footprints). 

You can pay for the aditional features as shown on their website 
with the full package only costing a few hundred pounds. This is 
great for hobby applications and ok for commercial prototyping 
however more detailed functions are not supported as with OrCAD.

I really like the microprocessor functionality in this package 
alhough it is not much use for MSP430 development. They 
currently support PIC's, AVR, 8051 and the Basic stamp.

Hope this is of some help,



Colin Bowdery.

RE: Eagle

There is a beta version of Eagle for the Mac (OS X, using X11 which is
now
supported by OS X). Note the warnings, but I have been playing with it a
bit and it hasn't crashed or done anything strange yet:

	http://www.cadsoftusa.com/betatest.htm

I am learning Eagle and it will be nice to have a choice of platforms
when the OS X version is officially available. Another reason is that
I have a 23" LCD on the Mac which is very nice for CAD.

I have a look to the site. First impression is quite good, Informations are
clear and funtionality seems more then I'm loking for. I downloaded all
files and in a week time I will experiment it.
Many Thanks, Paolo.
