Dear Fahad,
I only read now you mail(s) on mems-talk archive. Actually, it seems
that we could have been developing a software which is what you were
looking for.  It is a C simulator, which runs both under linux and
Windows, that simulates current conduction into a (arbitrarily) doped
silicon layer, and shows the evolution over time of the crystalline
silicon/porous silicon interface under different biasing conditions.
Results do not perfectly match real profiles, mainly because of the lack
of experimental data from literature to tune the simulator.  We plan to
put the simulator executable publicly available, but still lacked the
time to write a short user's manual.  As this is experimental code, it
is definitely user-UNfriendly, and so a manual is mandatory.  I will
(hopefully soon) inform you about any news concerning this aspect.
Meanwhile, if you have a specific problem you could describe me the
geometry and current conditions and we could run a few simulations for
you.
I also send you a proof of a work we presented at the European Material
Research Society in Strasbourg last year, and you could maybe have a
better idea of wether this simulator fits your needs.
