Hi,

The Qucs project was a project to link Qucs, a GPL circuit solver with a 
nice graphical interface, and many advanced features to Octave. Qucs is 
a circuit simulator, but also has many ideal elements such as 
differentiators, step functions, interpolation routines etc.

Regarding the interface to Qucs, the m-code link to Qucs works, most 
Qucs functionality is now in a shared library, and it can be called from 
m-code quite easily. The only missing piece for Octave is that the 
interface is based on classdef, and requires you to be able to call 
parent class function using the @ syntax, which last time I checked had 
not been implemented.

What this means, is that Qucs is not very far from being a free version 
of The Mathworks Smulink(TM) product (although not compatible in any 
way). I could therefore imagine some projects around this, if the 
classdef was ready in time (I'm not demanding this or anything, just 
saying this is required before this can be used with Octave).

In terms of circuit simulation, such a system would be far in advance of 
Simulink and its SimPowerSystems add-on.

Regards,
Richard
