Research on Key Techniques of Virtual Test on Switch Port of FC Switch Chip

新一代飞机航电系统采用光纤通道为主干通信网络,FC交换机是其网络拓扑中的核心设备。因此,研制FC交换机核心芯片是构建航电FC网络的关键。在芯片研制过程中,对交换机芯片的核心电路—交换端口进行充分虚拟平台仿真验证,能够有效缩短全芯片设计中的查错纠错时间,从而降低风险,加快芯片的设计、验证进度。文中结合多端口FC交换机芯片特点,对其交换端口核心电路的验证策划、验证平台搭建以及验证实施等关键技术进行了研究,并通过文中描述的验证策略对其进行了验证。结果表明,交换端口的功能和性能均满足设计需求。

The avionics system of new generation aircraft uses fibre channel as the main communication network,FC switch is the core equipment among the network topology. So the importance of building avionics FC network is developing a FC switch chip. With developing 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.
