From: rohit.nadig@gmail.com on 2 Oct 2006 14:44 Am I the only one that feels that this thread is in the fringe of what most of us understand as computer architecture? I plead the individuals of concern here, to not be offended. I see that you are having an interesting conversation. But, can you spare us geeks the burden of the information, and perhaps engage in this conversation in a more suitable news group (alt.*).

No, and I apologise for having inadvertently started it :-( Regards, Nick Maclaren.

Are those tasks inherently single-threaded, or is that just the way your tools vendor coded them? I would have expected synthesis to have about the same opportunities for parallelism as other compilers: essentially what parallel make can give you. Place and route might be parallelisable, if they operate in an iterative try-multiple options minimisation style. Don't know about timing analysis. There's lots of independent stuff going on in most FPGAs, though, so I'd think that there's ample opportunity to do that in parallel too. Multi-processors have been available in the higher-end CAD workstation arena for a long time. I would have thought that the code would be using them, by now. Cheers, -- Andrew |
