XC4VFX12 -- availability?

I just made the mistake of spending a month designing a board for the Virtex-4 FX without first checking availability. Xilinx has been talking about the part for nearly a year, there are dev boards all over the place, surely there must be silicon available, right? Now both Avnet and NuHo are telling me that Xilinx is having "yield problems" and it could be as late as June of 06 before they're shipping silicon. Has anyone had any luck finding these parts? I'm just looking for a couple samples to finish my thesis project, and it would be nice to not have to spend another month redesigning this hardware...

Thanks, ...Eric

scary business we are shipping products with FX12 on board and we are just about to re-order parts, I know that all FX MGT production silicon is not be expected before Q3, but I did not assume any issues with FX12 part, as it was available looong time ago.

it could be that disties dont wanna have ES silicon in stock and they are using standard worst case lead time, so thats why it looks so bad for you. I bet FX12-ES in sample quantity should be obtainable.

there isnothing muchonline, but the FX12 based modules are actually shipping now, so knowing that the FX12 supply is ok is quite a bit important

Yeah,

If there's no issues with FX12, meaning no important design errors (apart from the system manager which was cancelled..), yield problems etc, then if sample quantity is all that's available, it can only be because all devices are being sold to big customers. I guess the 80 nm factories in the world are being overloaded with work on producing new 80 nm chips from different companies and I can think of one company that is having a lot of new chip revisions done these days...

FX12 parts are available. If your distributor does not stock them, it might be because he does not want to stock ES-type parts that he cannot return. Just ask for "FX12 CES" or ask for "FX12 Production SCD0965". The latter is the same die, but it has gone through production qualification. There are some minor errata that you can get from your distributor.
