Avnet is sole disti for Xilinx, now lets see what
Avnet says:

searching for Spartan-6
all items are no stock, with notice factory leadtime 16 weeks
but some items have extra note, "stock in asia"
good this means there is stock?
but what does the "stock in asia" link do?

it opens a popup window saying: no stock,
factory leadtime 143 weeks!

143 weeks leadtime on spartan-6?

should we all smile or cry?

It's even better when that 143 week lead time
comes through as a
formal quote. I have a number of Jan2013 delivery quotations. I'm sure
it's not as bad as that but the people on the ground at Avnet think
but they do go by their system quoted leadtimes.

Meanwhile I will announce a new Spartan-6 board later this week. We
have a limited supply of silicon sold to me by Nuho when they were
still franchaise but after that I guess it's maybe a wait until 2013.

Switch to Altera. I've never heard of delivery problems for the Cyclone 2,
which a customer is still using for a product which I helped to program.
Even for the latest Cyclone 4 there are already some chips available in the
Altera online shop. For the Cyclone 3 device there are hundreds of each
type in stock. Digikey, Farnell and other distributors have it in stock,
too.

16 weeks should be enough time for changing a design from one vendor to the
other, if you didn't use special features which are not available in the
other FPGA. And in the end you'll have a more FPGA independant design, if
you need to change it again :-)

Digikey now also  has 251 XC6SLX items. All not on stock, but must parts
scheduled around mid of august .

On some these they will come back and say order
book isn't open.
That's what happened to me. I placed a pile of orders this way when
this list appeared mid-week as a emergency way to get silicon and an
alternative to Avnet. However I suspect, given what I have seen, that
they will meet these dates but you never know/

What's the lead time for Spartan 5 parts?  Or how about Altera or
Lattice parts?  Why look for trouble?

I believe the lead time for Spartan 5, as with Spartan 4, is
much longer, likely approaching infinity.

Spartan 6 does have some interesting new features previously
only in Virtex devices.

I think the problem is that if people want the
very latest and greatesttech they need to put up with long lead times and bugs in the developmentsoftware. Personally I would wait until these things are resolved and justuse a slightly older techology.

Don't you mean Spartan 3E?

Don't know about Lattice.

As to Altera, Spartan 6 has many features not available in Cyclone2/3.
Lead time for Cyclone IV is probably not much shorter than for Spartan
6. Also, Spartan 6 is both build on more modern silicon process and
has more advanced LUT architecture than even Cyclone IV, so, in
theory, it should be faster.
Of course, there is Arria II GX that easily matches (and beats)
Spartan 6 feature4feature and MHz4Mhz. It is even sort of available,
at least some parts. However, Arria II GX is more like mid-cost device
rather than low-cost.

Around 10/2009 we were forced by our customer to work with Stratix IV
GX. What a nightmare! Until Quartus9.1 SP1 pretty much nothing worked
as expected. Were we starting the same project around 03/2010 it would
be walk in the park.
