篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了DE2-115创建Web Server详细步骤（Quartus 13.1）相关的知识，希望对你有一定的参考价值。
这里综合了Altera提供的各种文献和实例，在最新的Quartus 13.1构建。
1. New Project
2.Create New System
Ctrl+R，将时钟Name更改为clk_50，频率为50MHz
加入altpll组件，c0->100MHz，作为系统时钟；c1->100MHz，相位延迟-2ns，作为SDRAM时钟；C2->10MHz，作为其他LCD，LED等时钟；可选C3->65MHz，作为VGA像素时钟。（图就不改了）
在View菜单中，打开Clocks视图，修改时钟名字提高易读性。分别是altpll_sys, altpll_sdram, altpll_io, altpll_vga。
altpll.inclk_interface设置为clk_50，双击altpll的export，导出areset，locked，phasedone。这个locked信号可以做nios的reset
加入NIOS Processor，JTAG UART（IRQ 0）
加入SDRAM controller，导出wire，地址锁定为0x0
各component的clk均为altpll_sys，sdram的Avalon Memory Mapped Slave连接到cpu.data_master和instruction_master。
添加Generic Tri-State Controller，作为Common Flash Interface，名字为ext_flash（和web server app模版名字相同）
添加Tri-State Conduit Bridge作为Flash的端口，连接ext_flash.uas->cpu.data_master，ext_flash.tcm->tristate_conduit_bridge_flash.tcs，导出tristate_conduit_bridge_flash.out
add Triple-Speed Ethernet，名字为tse_mac（web sever模板中的名字），Core Variations: 10/10/100Mb Ethernet MAC，Interface RGMII，Include MDIO Module (MDC/MDIO)
terASIC提供的DE2_115_Web_Server.qsys中Triple-Speed Ethernet的名字有错（13改了名？）。可用文本编辑器修改此qsys文件，查找triple_speed_ethernet，修改module为：
<module kind="altera_eth_tse" version="13.1" enabled="1" name="tse_mac">
添加On-Chip Memory作为 Descriptor Memory
add scatter-gatter dma controller，Memory To Stream，Source error width为1，作为发送DMA
再次add scatter gather dma controller，Stream To Memory，Sink error width为6
tse, descriptor memory, dma时钟都是alt_sys。
tse.control_port->cpu.data_master
tse.receive_clock->altpll_sys
tse.transmit_clock->altpll_sys
接收链路：tse.receive->sgdma_rx.in, sgdma_rx.m_write->sdram.s1
发送链路：sgdma_tx.m_read->sdram.s1, sgdma_tx.out->tse.trnsmit
sgdma_rx, sgdma_tx两者的descriptor read 和descriptor write，都连接到descriptor_memory.s1，->cpu.data_master
sgdma_rx设置irq 2，sgdma_tx设置irq 3
根据提示导出tse的conduits
以上时钟都适用系统时钟，mapped slave都连接到cpu.data_master上，包括altpll.pll_slave
添加Avalon-MM Clock Crossing Bridge，设置适当深度
clock_crossing_bridge.m0_clk->altpll_io，clock_crossing_bridge.s0_clk->altpll_sys，clock_crossing_bridge.s0->cpu.data_master。
除非特别说明，以下系统的低速设备都使用altpll_io和clock_crossing_bridge.m0连接到clk和mapped slave (s1)。
add Interval Timer (IRQ 1), System ID, LCD 16027, LED pio （led_pio）, SWITCH pio, Seven Segment Display pio, KEY pio (可将KEY[0]留作全局reset)
这里强调一点：System ID是很重要的一个设备，设定一个常数，和timestamp配合判断NIOS和你的BSP是否匹配，不要在Run Configuration 中采取 Ignore mismatched system timestamp，我常常因为这个 mismatch 的提示才知道bsp不匹配。
修改cpu，reset vector memory 和 exception vector memory 都设置为 sdram.s1
菜单System -> Create Global Reset Network
System -> assign base address
FIle -> Save
应当只有一个警告
Warning: System.flash: Properties (isFlash,isMemoryDevice,isNonVolatileStorage) have been set on interface uas - in composed mode these are ignored
终于可以：Generate -> Generating...
Generate -> HDL example, copy
3. Create a new DDIO_OUT megafunction variation
width 设置为 1bit，Neither asynchronous clear nor asynchronous set ports options.
4. Create a new altpll megafunction variation
输入时钟为以太网的接收时钟，c0:125MHz; c1: 125MHz, 90deg; c2:125MHz, 180deg
5. New systemverilog file
paste HDL example
从terasic提供的例子中copy端口描述部分
修改nios的实例化部分
`define NET0
