Reusable Verification Environment for Verification of Ethernet Packet in Ethernet IP Core, a Verification Strategy-an Analysis

Design reuse and verification reuse are important to satisfy time-to-market requirements. Designer must be able to reuse Intellectual Property in the design as golden model. Reuse of verification environment across different designs of the domain saves time to market further and improves total design verification quality. The Physical Layer is a fundamental layer upon which all higher level functions in a network are based. However, due to the plethora of available hardware technologies with widely varying characteristics, this is perhaps the most complex layer in the OSI architecture. The implementation of this layer is often termed PHYsical layer device (PHY). The Physical Layer defines the means of transmitting raw bits rather than logical data packets over a physical link connecting network nodes.
