Chip simulation seems like it would be a pretty difficult problem to multithread, since everything depends on everything else - can you run those simulation tools on clusters (or even GPGPU)? Apparently Bulldozer, AMD's latest chip, is their first to start using automated design tools; one ex engineer claims that it resulted in 20% bigger and 20% slower designs: http://www.xbitlabs.com/news/cpu/display/20111013232215_Ex_AMD_Engineer_Explains_Bulldozer_Fiasco.html http://www.xbitlabs.com/news/cpu/display/20111013232215_Ex_A...
