摘　　要：基于网口的仿真器,提出了一种以NIOSII软核为核心,利用以太网控制器LAN91C111的设计方案,并给出了硬件电路、固件程序的设计。利用本仿真器通过第三方软件可以实现目标机的在线调试和在线编程。该方案具有很好的扩展性和灵活性,降低了软件的开发成本和硬件的实现风险。In this article,a new design of emulator is proposed which is based on Ethernet interface,choosing NIOS II soft-core and Ethernet controller chip LAN91C111 as the MCU. The hardware circuit and the Firmware is described in detail. The third-party software can interact with the emulator for in-system debug and programming. The design has a strong expansibility and agility. It also reduces the cost that used to develop software and the risk in the course of the hardware development.
