Sorry about that!  "circuit board" would have been too long.

It might be summarized like this.  We aimed to build something small
and simple, using a small fixed API, enabling straightforward
composition of part models (and their optional GUIs) based on a
hardware assembly metaphor.  It is suitable for consideration as an
integration platform for other simulators (interconnecting models from
different simulators, as has been done with BOCHS, and also with a
live Verilog system).  Its "plugin" mechanism allows separate
compilation and packaging of simulation components.  Most of its
library of models have *not* been particularly tuned for performance,
and the architecture generally considers this an internal matter for
each component model.

As far as project dynamics goes, its improvements in recent years have
been customer-funded, and most or all of them are being released into
the GPL free software pool.

Do you need elaboration on any of these or other points?
