Modern high-speed I/O equalization schemes typically include both fixed (programmable) and adaptive components to ensure signal integrity even in adverse system conditions. What tools are available to ensure that these equalization techniques are working properly on a given system?
Whatโs cheaper, faster, and more powerful than an oscilloscope, when it comes to validating high-speed signal integrity? Why, a software application using embedded instruments, of course. How is this possible?
In my last few blogs, Iโve talked about the challenges of testing QPI, PCI Express, SATA 3, and DDR3 memory. These buses are common to many Intel Sandy Bridge and Ivy Bridge motherboard designs. Should test engineers take chances and just not test them?
Serial ATA 3 (SATA 3, or SATA III) is a differential bus running at 6Gbps. Itโs commonly used on computer motherboards, such as notebooks, to connect to mass storage devices. How do you know if your hard disk or flash drive is running at full speed?
Brian Bailey, editor of EETimesโ EDA Designline, recently penned a blog questioning the ubiquity and value of embedded instrumentation within chips. Itโs a fascinating and timely read, and Iโd like to put my two cents worth inโฆ
