官方的FPGA开发套件提供了与Marvell 88E1111 PHY工作的实例，但俺没有银子，最便宜的DE2开发板也得3000块吧。我用手头的EP2C8Q208C8搭建了一个测试平台：
(1)发送测试：
(2)接收测试：
Id1 = 0x13, Id2 = 0x78e2.
Wait reset.
Reset ok.
config = 0x3100.
MII status = 0x7809.
Reg 4 = 0x1e1.
Wait Auto-nego...OK.
config = 0x3100.
MII status = 0x782d.
MII status2 = 0x4780.
Link OK.

(3) tse 12.1版本已经可以支持IEEE 1588V2精密时间协议(PTP)协议。
IEEE1588的全称是“网络测量和控制系统的精密时钟同步协议标准”，是通用的提升网络系统定时同步能力的规范，在起草过程中主要参考以太网来编制，使分布式通信网络能够具有严格的定时同步，并且应用于工业自动化系统。基本构思是通过硬件和软件将网络设备（客户机）的内时钟与主控机的主时钟实现同步，提供同步建立时间小于10μs的运用，与未执行IEEE1588协议的以太网延迟时间1，000μs相比，整个网络的定时同步指标有显著的改善。
