1. GTX IP核的創建

此選項根據你所用的FPGA型號確定GT類型，我所用的是7k325t系列，故GT類型為GTX

接下來，開始配置IP

首先，這里的時鐘頻率是連接FPGA高速bank上的差分時鐘，根據自己項目實際需求進行配置即可

再者，強調一下，因為我的項目中對應的是光纖收發，線速率根據實際光口的不同進行適配選擇即可！

還有，估計有和我當時一樣的初學者看本篇文章，所以我就本著我當時初學時復雜且全是問號？的心情補充一下。開始廢話（高手跳過）：我這里是兩個高速收發器，亦就是兩路光纖收發，怎么來的呢，當然是選的，怎么選的呢，好問題，用你的鼠標選中左側灰色的收發器框圖，然后點擊選擇我用小紅框標記的選項“Use GTX X0Y6”，然后框圖從灰色變成黃色了，這個時候神奇的事情就發生了，艾~突然就又增加了一個，聰明的你就以此類推了，哈哈哈哈，這個框圖你得對照你項目中實際原理圖看仔細，你用的高速收發器是在哪個FPGAbank上的哪個坐標就行，不過也沒關系，就算這里你選錯了，到時候你約束引腳約束對了就可以了，不影響的。

好了，接著選

這里就開始配置收發器了，外部數據寬度，也就是咱們邏輯里面最終要用到的數據位寬，這里我用的是32位，根據你項目需求用就行了，就算其他位寬的，你用異步fifo轉不就行了，這能難倒咱們邏輯工程師嗎？開玩笑呢！好，編碼一般8B/10B，內部數據位寬就得注意了，這個地方還與最終咱們使用的userclk有關，在ug476手冊里面第100頁有具體講解（廣子：上xianyu搜麻醬就燒餅，獲取xilinx全系列文檔手冊），可以自己查查，我就簡單贅述兩句: TXUSRCLK Rate=Line Rate/Internal Datapath Width,如果這里你的內部位寬是20的時候，你最終的TXUSERCLK2=TXUSERCLK/2，具體細節深耕數據手冊！

然后就是本頁其他配置都是默認的，不用管（如果有特殊需求除外）

接著選，Comma Value我用的K28.5（BC碼），具體看我源碼中如何使用，其他配置默認！

接著來，不用管，繼續默認

繼續來，勾選USE CLOCK CORRECTION，其余默認

最后檢查所配置結束的IP參數，強調：最后我們在邏輯里面發送用的時鐘域是TXUSRCLK2，以此類推，接收用RXUSRCLK2！！！

2. 搭建工程且編碼

好了，咱們開始爆改啊啊啊啊啊啊啊！

生成例程，完了只需修改例程頂層模塊gtx_aurora_x2_exdes.v文件即可

工程結構：

我在編碼模塊中用到了狀態機，而在解碼模塊中沒有用到，原則是：怎么簡明怎么來

頂層：

描述：頂層當中的sys_on_sim在實際使用時換成sys_on即可！

打包編碼：

編碼選用8b/10b，comma值用k28.5（BC碼），有同學就好奇，k28.5為啥就是BC碼，好吧，我當時也不懂艾，好在去取經了，現在就給你道來：0XBC=0B1011 1100，好，重點來了，0D28=0B11100,0D5=0B101,聰明的你已經發現了，BC=5和28相結合，K28.5分別把28和5換成二進制，然后放一起，再重新組合，低三位101放前面，高五位放后面，那不就成8‘b10111100即8’hBC了嗎，以此類推，其他的k碼怎么算你就知道了。關于k碼換算，你得去看文章，我這里只是讓你簡單了解一下，別迷糊了，BC是怎么來的不知道！！！

我的編碼順序：

1.等待有效數據的到來，這個過程一直向鏈路發送空閑碼，訓練鏈路

2.等有效數據來了發送幀頭，進行編碼

3.開始發送有效數據（此項目我發送的是順序數據，但是我在代碼中預留了關鍵握手信號vld和rdy，有需要的同學后期自己在我的代碼上面改就行了）

4.有效數據發送完成，進行編碼

5.發送幀尾進行編碼

6.接著發送空閑碼進行編碼

解包解碼：

心善的我再提示一下：解碼出來的時鐘域最后你得換成你自己的系統時鐘域，不太明白的同學就又問了，怎么換時鐘域啊啊啊啊啊，還能怎么換，異步fifo，用爆FPGA芯片資源，用就行了。此項目我沒轉換紅紅火火恍恍惚惚

解碼思路：

根據自己定制的編碼協議進行解碼

1.先解數據幀頭

2.得到有效數據

3. 在線調試

調試思路：如果沒有多余的板卡，你就用ip核進行回環調試，具體看ug476手冊第88頁進行配置（廣子：上xianyu搜麻醬就燒餅，獲取xilinx全系列文檔手冊），近端pcs和近端pma，如果這樣調試通了，那基本沒問題了。

TX鏈路：

可以很清晰的看到，當我的sys_on拉高的時候，經過編碼后的數據包已經有效的發送出去了

RX鏈路：

可以看到，當我的vld有效的時候，接收到的正好是發送過來的順序數，和發送的有效數據包一致！

vio調試：

說明：

1.sys_on_sim是總的系統啟動信號

2.soft_vld是控制剩余的復位GT鏈路信號和回環測試的信號
