Part of it.

Most of that document talks about the behavioral side, appropriately
because that's where the complexity is.

Parsing is the easy part.  I have not found parsers that we can just
plug in to be very useful.

But since you asked .....

Gnucap has a parser and writer for the structural part, the part needed
for this, and a means to translate to and from some other simulation
formats such as spice and spectre.  There is work in progress
interfacing to geda schematics and the qucs simulator format.

Icarus Verilog and Verilator have parsers for the digital subset, as
part of their simulators.

ADMS implements the analog behavioral subset, and generates C or C++
code which can be used by a simulator.  It is used by NGspice, Qucs,
Xyce, and Gnucap.
