so what you really want to know is what hammer is best suited to work
with diffent types
of screws, nuts and bolts because screwdrivers and wrenches take up to
much space in
the toolbox ... ;)

pick an fpga that matches you needs, get and use the tools the
manufactures made for it,
you'll need their backend anyway. Program in verilog or vhdl thats
languages made for that
specific purpose

Not sure what you want to do. Describe a function in HDL and have it
spit out unit logic? I don't know of anything that does that. Some
tools have a logic viewer that might do it. I think Actel's is
included in the free tools, but I haven't used it yet (trying not to
use Actel, right now).

Jon,
Ok, thought about this a bit. Part of the problem is that the EDA
companies basically just provide a front end for the FPGA company's
tools. They don't try and duplicate that back end effort, it isn't
worth it for them. So, if you want to do more than just preliminary
designs for each vendor, you will still have to install X number of
starter editions for each vendor you want to try.

For the price, Altium at $3999 is probably the cheapest major company.
When paired with their nanoboards, you can get a decent development
platform to really try things out. Their latest nanoboard is only
$399 and comes with a years subscription to the front end software.

There may be other small players, like Proteus, but I am unfamiliar
with the tools.

Clearly I'm not a digital guy... at least beyond pure combinational
reduction, which I actually used to teach about 40 years ago.

What I'd like is some tool that took in a truth table, each line
representing states at that clock tick, spitting out gates, flops,
etc., to implement that ;-)

I know. I know. Hire you ?:-)

I like the analogy.

Unless, for some reason, you're pushing the envelop, this is the only
way to go. Third party tools are very good, but incredibly costly. If
the performance, or device size, isn't needed the manufacturer's tools
work very well now. The only possible exception is simulation where
the manufacturer's tools are limited (crippleware versions of
ModelSim, usually). ModelSim is expensive too, though.
