The avionics system of new generation aircraft uses fibre channel as the main communication network,FC switch is the core e-quipment among the network topology. So the importance of building avionics FC network is developing a FC switch chip. With develo-ping of the chip,the core circuit of the switch chip—sufficiently virtual platform for validation of switch ports can effectively shorten the error correction time in the design of whole chip. It also can lower risks and speed up the chip design and verification. Combined with the characteristics of multiple FC switch ports chip in this paper,the switch port core circuit verification planning,platform building and im-plementation of verification,and other key technology are studied,and described by the validation strategy is verified. The results show that the function and performance of the switch ports can meet the design requirements.
