Manufacturers that put more than, say, 0.001% "broken" parts out onto the market should immediately be forced out of business. come on, that would be too costly, (testing costs will be passed on to the customer) I'd say I'd agree with you if it was 0,1% (one in thousand) So, it wouldn't bother you that one out of every thousand boards that you built had a processor that didn't execute, say, CJNE properly? If you use a part that works only under the circumstances under which you require it to function, aren't you concerned that the "broken" features are an indication that the device itself is defective?
I see absolutotally no reason to be concerned with whether a part can do something I do not need. I use the SILabs f12x parts becuse of their speed, they have tons of analog functions, why would I worry about (testing) those - I do not use them. So it wouldn't cause you any heartburn if that 1 in 1000 processors that didn't execute CJNE properly was in use in a system that didn't happen to use CJNE? Wouldn't you worry that this failure was, perhaps indicative of a greater flaw in that part? I have had, when working at the bleeding edge, to work with defective parts known defective where the defect was "workaroundable" (sorry bad word/grammar) and also parts with known defects that did not affect my project. (just look at final errata for first spin parts). They're kind enough to tell you in advance, that these parts are not "firing on all cylinders" and what to expect. If one in every 1000 parts is defective, and you happen to buy that one, they haven't told you it's defective, and they haven't told you which functions work and which don't, and, in fact, you don't know it's defective at all, so you assume it works. That can lead to the waste of a lot of time. That's why I don't buy cars made by FORD, GM, or Chrysler
If you bought one of the above and the gas gauge did not work, would that keep you from driving? Erik I'd never, Never, NEVER, find myself in that situation, because I don't even consider their products, thanks to their business ethics, or lack thereof. I've been bitten by that problem, back in '71, and wouldn't like to repeat it. It wasn't fun. Other car makers check their products out before delivering them to their customers. U.S. makers simply let the customer find the flaws, if they can. RE |
