<The Mot processor guys I know no longer work there so I can't confirm the problem side but it seems likely to me that they most likely have problems with the design.Isn't it true that Mot is having good success with SRAM chips on the same process? If so, I would be hesitant to conclude that they are having process problems, especially when AMD is also confirming the good yields on that process.> You certainly may be right on the design issue. I really didn't understand the complexity involved in ALTIVEC. Maybe, that's why IBM didn't embrace it. A bad decision??? However let me play devil's advocate. I think Motorola's stand alone Cu BEOL SRAMS are in .25um technology (Can anyone confirm/deny this?) If so, .25um is a lot easier than .18um. Also SRAMs require only 3 levels of metal while Athlon will likely require seven. Also, most SRAM designs I've seen don't fully test the BEOL groundrules as the processor will. Also, AMD said equal yields as Al SRAMs in .25um. They said they yielded K7 in .25um Cu BEOL. Did they say they yielded equally as well as .25um Al K7s. NO Why not? Because, maybe they didn't. Now extrapolate that to .18um. I caution this thread not to take the processing issues lightly. THE WATSONYOUTH
