Lately I did some brief overview of high-level hardware modeling
libraries (frameworks) for programming language Haskell (see
http://haskell.org).
While all of the available tools are either too low-level or
semi-functional (Hawk - http://www.cse.ogi.edu/PacSoft/projects/Hawk/ -
I failed to compile examples) I succeed to reconstruct some essentials
that allows high-level models to be implemented quick enough.
Although i see the sense behind using haskell or hawk for high level
modeling/simulation, i advice against using it. Learning an additional
language to get going is a lot of work and might produce unneccesary
delays and problems. Also having all simmulation from highlevel to
low level in the same language has the advantage that we can use
the same simulation enviroment to verify everything.
But with Haskell you can simulate very high level properties of
architectures much faster than with System C++.
I know what I am saying. I actually speak from experience.
If there is a need to use a different language than a HDL,
we should use C or C++ as with those we have at least a chance
to integrate it into a simulator.
Why should we use them? They are sooo XX-century... ;)
After initial turnaround of simulations and agreeing on some
architecture we could use SystemC.
