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. -- glen
From: maxascent on 5 Jul 2010 06:49 I think the problem is that if people want the very latest and greatest tech they need to put up with long lead times and bugs in the development software. Personally I would wait until these things are resolved and just use a slightly older techology. Jon --------------------------------------- Posted through http://www.FPGARelated.com

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.

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. |
