Opis

Efficient Test Methodologies for High-Speed Serial Links describes in detail several new and promising techniques for cost-effectively testing high-speed interfaces with a high test coverage. One primary focus of Efficient Test Methodologies for High-Speed Serial Links is on efficient testing methods for jitter and bit-error-rate (BER), which are widely used for quantifying the quality of a communication system. Various analysis as well as experimental results are presented to demonstrate the validity of the presented techniques.

With the increasing demand for higher data bandwidth, communication systems’ data rates have reached the multi-gigahertz range and even beyond. Advances in semiconductor technologies have accelerated the adoption of high-speed serial interfaces, such as PCI-Express, Serial-ATA, and XAUI, in order to mitigate the high pin-count and the data-channel skewing problems. However, with the increasing number of I/O pins and greater data rates, significant challenges arise for testing high-speed interfaces in terms of test cost and quality, especially in high volume manufacturing (HVM) environments. Efficient Test Methodologies for High-Speed Serial Links describes in detail several new and promising techniques for cost-effectively testing high-speed interfaces with a high test coverage. One primary focus of Efficient Test Methodologies for High-Speed Serial Links is on efficient testing methods for jitter and bit-error-rate (BER), which are widely used for quantifying the quality of a communication system. Various analysis as well as experimental results are presented to demonstrate the validity of the presented techniques.
