# 2.光纤通信

|
||
## 2.1 章节导读
|
||
|
||
在现代高速通信系统中，光纤通信作为一种重要的信息传输手段，广泛应用于数据中心、城域网、广域网以及各种嵌入式高速数据传输场景中。相比传统电缆传输，光纤具有带宽高、传输距离远、抗电磁干扰能力强、保密性好等显著优势，是实现高速、高可靠性通信的关键技术。
|
||
|
||
随着FPGA在通信领域的深入应用，基于FPGA的光纤通信系统设计成为一项非常实用的技能。在本实验中，我们将基于开发板配套的光纤接口模块，设计并实现一个基础的光纤通信收发系统。通过本实验，同学们将掌握光纤收发器（SFP模块）的基本使用方法，了解高速串行通信，8b10b编码等概念，并学会如何通过FPGA完成数据的高速发送与接收。

### 2.2.1 8B10B编码
|
||
|
||
8b/10b 编码常用于光纤通信和 LVDS 信号中，其主要目的是解决信号传输过程中的直流不平衡问题。由于串行电路通常采用交流耦合的方式（串接电容）我们知道理想电容的[阻抗](https://so.csdn.net/so/search?q=阻抗&spm=1001.2101.3001.7020)公式 ，通过这个公式可以知道，频率f越高，阻抗越低，反之，频率越低，阻抗越高。

如上图所示，当码型是高频的时候，基本可以不损耗的传输过去，但是当码型为连续的0或者1的时候，电容的损耗就很大，导致幅度不断降低，最严重的后果就是无法识别到底是0还是1，因此8b/10b编码就是为了尽量把低频的码型优化成较高频率的码型，从而降低阻抗带来的损耗。以光模块为例，它只能传输“亮”或“不亮”两种状态，即二进制的 1 和 0。当传输数据中出现长时间连续的 1 或 0（如 111111100000000)时，线路中电容的损耗就会很大，从而无法准确采样，进而造成误判。
|
||
|
||
同样，在 LVDS 高速传输中也存在类似问题。如果传输的 0 和 1 数量长期不均衡，线路上的基准电压会发生偏移，影响信号的正确识别。
|
||
|
||
因此，8b/10b 编码通过对每 8 位数据编码成 10 位信号，实现传输数据的直流平衡和足够的码流转换，也就是保证串行数据不会连续出现1和0，从而提升系统的可靠性和抗干扰能力。
|
||
|
||
那么8b10b编码是如何将8bit数据编码成10bit数据的呢？假设原始8位数据从高到低用HGFEDCBA表示，将8位数据分成高3位HGF和低5位EDCBA两个子组。经过5B/6B编码，将低5位EDCBA映射成abcdei；高3位经过3B/4B编码，映射成fghj，最后合成abcdeifghj发送。

可见8b10b编码是基于5b/6b和3b/4b之上的。

上述两张表格就是5b/6b和3b/4b编码表，那我们先来看懂这两张表格。
|
||
|
||
首先是D.x.y，将低5位EDCBA按其十进制数值记为x，将高3位按其十进制数值记为y，将原始8bit数据记为D.x.y。例如8bit数据最大为255，也就是111_11111，低五位是11111，也就是十进制31，高三位111，是十进制7，所对应的8b10b就是D.31.7。这也说明了上述5b/6b编码最大为D.31，3b/4b编码最大为D.x.7。
|
||
|
||
至于RD = - 1和RD = + 1。+ -分别表示0比1多，1比0多，多的个数是一样的，而且最多多两个。当0和1一样多时便没有+1-1之分。编码的初始化状态是-1。
|
||
|
||
对于D.x.7† ，当和5B/6B组合时D.x.P7和D.x.A7编码必须选择一个来避免连续的5个0或1。D.x.A7用在：x=17 x=18 x=20当RD=-1时； x=11 x=13 x=14 当RD=+1时。 其他情况下x.A7码不能被使用。
|
||
|
||
表里面D.23，D.27，D.29，D.30后面带 †，它有自己的特殊配对规则，当x=23 x=27 x=29 x=30时，3b/4b这边使用K.x.7进行编码。

8B/10B标准中使用了12个特殊的控制代码，他们能在数据中被发送，利用这些控制字符，可以组成各种控制语句，其中K.28.1 K.28.5 K.28.7被称为逗号字符，利用序列检测状态机检测逗号字符，以保证在串行数据接收过程中接收到数据的唯一性。如果没有逗号字符，串行接收设备将不知道数据是从哪一位开始，当序列检测器检测到逗号字符时就确定了字符的开始。

### 2.2.2 hsstlp ip核
|
||
|
||
实验板小眼睛盘古pg2l100h有2个hsst硬核，共8路全双工高速串行收发接口，每个接口最高支持6.6Gbps的速度，其中4路用于PCIE，2路用于SMA接口，2路用于sfp光纤接口。有关hsstlp的内容可以参考官方手册。

## 2.3 实战演练
|
||
|
||
### 2.3.1实验目标
|
||
|
||
利用板载一路sfp光纤通道接收来自ctrlFPGA的数据实现光纤通信。
|
||
|
||
### 2.3.2硬件资源
|
||
|
||
实验板上有2路sfp接口全部与ctrl-FPGA相连。

### 2.3.3程序设计
|
||
|
||
首先我们应该学会配置并使用hsst ip核。
|
||
|
||
在ip核的配置界面可以看到可以配置4个通道的状态，分别是全双工，仅接收，仅发送和不使能。同时还可以给每路通道选择不同的标准协议例如GE，XAUI等，勾选Protocol Default Setting后可以使用该协议的默认配置。也可以自定义协议传输。
|
||
|
||
在本次实验中，我们将通道3设置成全双工，自定义协议，线速率5Gbps，编码选择8b10b，传输和接收的数据长度选择32位，PLL的参考时钟为125M。配置图如下：

|
||
图5.hsst ip核 <!--标题-->
|
||
</center>
|
||
</div>
|
||
|
||
在Alignment界面，可以配置对齐（word alignment）的模式，对齐所用的K码，多通道绑定（channel bonding）的模式，以及高速传输时出现的时钟偏差补偿（Clock Tolerance Compensation），具体使用可以参考hsst手册。

本次实验配置字节对齐模式为用户自定义，K码选择K28.5，不使用通道对齐和时钟偏差补偿。配置如下图所示：

在Misc界面选择使用官方复位程序，参考时钟27M（板载时钟），复位时钟个数为32767，接收模式（RX Termination Mode）选择外部AC，内部DC。配置如下图所示：

生成ip核后，我们将ip核例化在顶层文件中，目前配置的ip核包括复位所需要的信号，重要的状态信号，传输时钟i_p_tx3_clk_fr_core，传输的32位数据i_txd_3，传输的数据类型i_txk_3，接收时钟i_p_rx3_clk_fr_core，接收的32位数据o_rxd_3，接收的数据类型o_rxk_3。这里解释一下txk和rxk，这个信号是4位的，每一位对应txd和rxd信号的8位数据，1表示该8位数据是k码，0表示改8位数据是普通数据。参考代码如下：

到现在为止，我们已经可以接收和发送数据了，但使用的时候会发现一个问题，如下图所示，我们发送的数据是0xc5bcc5bc,但接收到的数据却是0xbcc5bc5，数据出现了移位，这是为什么呢？这是因为发送编码是8b10b，是以8位数据为一个基本单位进行发送的，虽然发送数据是0xc5bcc5bc，但是在串行通信中，他并不知道你发送的32位数据是以c5开头还是以bc开头，前面在ip核中设置的word alignment正确的对齐了BC（k28.5）这个字符，正确的接收了字节数据，但32位数据中字节顺序需要我们自己去调整。（因为设置ip时用的自定义模式）。

为了解决这一问题，我们也要给他设计一个模块，使他自动实现接收数据与发送数据一致，不会出现错位。在本实验中空闲时发送逗号字符K28.5 （BC），有数据要发送时发送32位数据。根据此格式设计对齐模块参考代码如下：
|
||
|
||
```Verilog
|
||
module Word_Alignment_32bit (
|
||
input wire clk ,
|
||
input wire rstn ,
|
||
input wire [31:0] data_bf_align /* synthesis PAP_MARK_DEBUG="1" */,
|
||
input wire [ 3:0] rxk /* synthesis PAP_MARK_DEBUG="1" */,
|
||
output reg data_valid /* synthesis PAP_MARK_DEBUG="1" */,
|
||
output reg [31:0] data_af_align /* synthesis PAP_MARK_DEBUG="1" */,
|
||
output reg data_done/* synthesis PAP_MARK_DEBUG="1" */
|
||
);

### 2.3.4仿真验证
|
||
|
||
本实验不进行仿真，可以点击工程目录下ipcore文件夹下，hsst参考设计中sim文件夹的sim.bat文件进行仿真。
|
||
|
||
### 2.3.5上板验证
|
||
|
||
上板前要先进行管脚约束。端口除了板载时钟，复位以及led，还需要添加以下约束：
|
||
|
||
```fdc
|
||
define_attribute {p:i_p_refckn_0} {PAP_IO_DIRECTION} {INPUT}
|
||
define_attribute {p:i_p_refckn_0} {PAP_IO_LOC} {AB11}
|
||
define_attribute {p:i_p_refckn_0} {PAP_IO_UNUSED} {TRUE}
|
||
define_attribute {p:i_p_refckp_0} {PAP_IO_DIRECTION} {INPUT}
|
||
define_attribute {p:i_p_refckp_0} {PAP_IO_LOC} {AA11}
|
||
define_attribute {p:i_p_refckp_0} {PAP_IO_UNUSED} {TRUE}
|
||
|
||
define_attribute {i:hsst_inst.U_GTP_HSSTLP_WRAPPER.CHANNEL3_ENABLE.U_GTP_HSSTLP_LANE3} {PAP_LOC} {HSSTLP_364_0:U3_HSSTLP_LANE}
|
||
define_attribute {i:hsst_inst.U_GTP_HSSTLP_WRAPPER.PLL0_ENABLE.U_GTP_HSSTLP_PLL0} {PAP_LOC} {HSSTLP_364_0:U0_HSSTLP_PLL}
|
||
```
|
||
|
||
该语句主要约束hsst参考时钟管脚，hsst所使用PLL（PLL0），以及hsst使用的通道。其他约束可以参考工程目录下ipcore文件夹中hsst内的参考例程。
|
||
|
||
完成管脚分配之后就可以生成sbit文件，将文件提交到网站后点击烧录，即可将sbit下载到实验板中，在摄像头页面即可观察到8个led中前四个亮，后四个分别为不亮，不亮，亮，不亮的状态。前四个亮表示hsst中pll和rx，tx通道初始化成功，最后两个led，led1亮表示接收的与发送的数据相同，led0不亮表示未经32位对齐模块处理的接收数据与发送数据不同。
|
||
|
||
## 2.4 章末总结
|
||
|
||
本次实验主要学习了高速串行通信的相关知识，初步学会使用hsst ip核。 |
