It should have "simulation models"  not "spice models".  Spice 
models are one kind of simulation model.  We should not restrict 
it to only one, especially when other kinds are already 
supported by geda-related tools.

For example, there are Verilog models, VHDL models, IBIS models, 
Spectre models, and many others.  They need to be all handled on 
an equal basis.

Also, there aren't really "spice models".  There are Hspice 
models, Pspice models, LTspice models, ...  and for spice-
derivative simulators under different names, .. Eldo, multi-sim.

There are often several different models available for a device.  
The database needs to accomodate multiple models that a user can 
choose from.

You don't need to explicitly support anything in particular, 
just general models, and more than one choice.

Also ..  Do not make the types of electronic components (diodes, 
resistors) inherent in the data base.  They are just parts, and 
all parts have schematic symbols, layout footprints, and 
simulation models.  Don't even try to make any specific device 
types inherent to the database.
