Alliance only implements a subset of VHDL. Migration
from RTL written for FPGAs to Alliance subset will not be easy.
Although Alliance does come with a tool (vasy) that can translate
between the two u still have to do a lot of work yourself which can
be quite time consuming.

The software packages u r talking about are not for EDA design. The EDA
tools that are availabe today for free still have to go a long way before
they
come at par with their commercial counter parts.

I mean u can't compare Alliance with Cadence's BuildGates for ASIC synthesis
or for that matter Synopsys DC!

The list to vcd covesion utility will not be able to convet 'enumerated
states' used in VHDL
for state machines other than that it should work fine with gtkwave.

The command line vesion does not come with an integrated waveform
display but otherwise it's quite fast and has no limits on speed vs
design size.
In this case u can only debug using texio

The script Visiblt is ok but if the .lst file is large (which in most
cases is)
it be comes very slow & will take a long time for the display to load
up.

There is another utility for converting .lst files to .vcd files but
that has some limitations as well

>>> Which limitations ? If .lst could be cleanly converted to .vcd, can
we use gtkwave to read the vcd file ?

The end line is u can't get the best of every thing for FREE!

>>> ? Have you heard about free software ? Gimp, Apache, Perl, Gnome,
Kde, Python, Php, Gcc, Mosix, Linux, *BSD, Mozilla, Savannah, Wikipedia,
openOffice.org, Transcode, OggVorbis, openssh, gpg, Mysql, PostgreSQL,
aren't good enought ? It's free in a sense of "libre". And there mostly
much better than there proprietary counter part !
Alliance is not finish but it's first goal was to design a complete
suite of EDA tools.

What the problem with simili ?

Does Visibly work well ?
