Re: gEDA-user: spice libs ( a little puzzled)

[asomers@xxxxxxxxx]

Spicelib (http://www.h-renrew.de/h/spicelib/doc/index.html) is an
attempt to provide a library of spice models for gnucap and ngspice
users that skirts licensing problems.  Much like how Gentoo's Portage
deals with non-redistributable but free-to-download software, spicelib
downloads models directly from the vendors, then patches them to work
with the open-source simulators. Patching is the real service that it
provides; due to incompatibilities between simulators, most vendors'
models won't work in the open-source simulators.

It's still a little rough around the edges, but you can use it to
quickly get about 1,500 spice models.  It does not, however, make any
gschem symbols for you.  You will still have to draw your own symbols
and then associate them with a model.

I have his permission to collect and publish the models under the GPL, but haven't gotten "a round tuit".
