【Abstract】Link-up Time test is one of the automotive Ethernet physical layer test items. It aims to examine the interface's ability of establishing connection of within a defined period,so as to ensure that the chip can respond to communication request rapidly. This article elaborates the theory,method and process of link-up time test based on a practical project,and provides useful reference to the sector.
