这几天Intel Sandy Bridge 所用芯片组的缺陷的事情闹得沸沸扬扬,其比较早的说法如下:

The flaw, which is found in the comany’s recently released Intel 6-series “Cougar Point” chipset, could cause the Serial-ATA(SATA) ports within the chipset to degrade over time, according to Intel. This could potentially affect the performance or functionality of any hard drive, DVD drive, and other device connected to the SATA port.

上文的大概意思是Intel确认了其6系列(学名“Cougar Point”?)的芯片组存在缺陷。会导致SATA接口老化,会影响所有的SATA设备,如硬盘,DVD等。


在现代的芯片设计中,质量保证(Qualification assurance,QA)的两个重要环节是验证和测试,验证一般和设计同步进行,并且一般是硅前的。而测试,往往是硅后的,是工程样片回来后进行的,是芯片投入市场-量产前的最后一道QA程序。
