URGENT: Need A Schematic Drawing tool

[Superman]

Hi all,

I have an urgent need for a transistor level (BJT, MOSFET, passive +
active element) schematic drawing tool ?? Anything free out there ??
BTW, an exisiting Visio template will also do the job.


Thanks for your input in advance,
Pete.

Pete:

Why not use Linear Technology's LT Spice to draw schematics, it's FREE.

You can export the schematics drawn in the "free" LT Spice program
[Thanks Linear Technology http://www.linear.com!] as bit maps to the
Windows clipboard and then paste the bitmaps into documents, etc...
with any Window's applications that support cut and paste.

Windraft is a limited pin count package.

True.
It's advantage is that the demo version does not limit the board area.
This makes it useful for large layouts
which have few pins (e.g. high-voltage layouts).

2 mistakes, however, Mark:
While Cadsoft EAGLE does have a free demo version,
its limit is not by pin count;
its limit is 100mm x 80mm layout with 2 sides,
1 sheet (untabbed) schematics.
EAGLE's big advantage is its modularity of upgrade possibilities:
if your only advanced need is to lay out bigger boards,
you can licence only the layout editor
(not the autorouter or multi-page schematic editor).

Your 2nd mistake is that anything below your double-hyphen-only line
is considered a sig (RFC-1855).
In most newsreaders, when someone replies,
that portion doesn't carry over into the blockquoted text.

You're correct about Eagle; I just meant that a freeware version was
available. Also, my sig line was gone (rebuilt the computer awhile
ago). Sorry...
