Agilex E-tile模块能否使用QSPFDD 400G光模块进行数据传输?如果可以的话,有没有相应的Demo进行参考。

Hi wang5,


May I know you are using which Agilex E-tile boards and QSPFDD 400G ? Please share the OPN number of the board and the information of QSPFDD 400G that you use if possible.


Best regards,

您好,我用的开发板是intel Agilex 7 FPGA F系列设备,OPN:DK-DEV-AGF014EA。其详细信息可以在这个链接查看英特尔® Agilex™ 7 FPGA F 系列开发套件(P-Tile 和 E-Tile) (intel.cn)。

QSPFDD 400G光模块使用的是思科的QDD-400G-FR4-S,如下图所示:

Hi wang5,

 

Intel Agilex® 7 FPGA F-Series Development Kit has 2x Standard QSFPDD supports both optical and electrical cable interfaces. So you can use the optical module to transfer the data.

 

Currently we don't have the demo about Agilex E-tile and QSFPDD 400G in our FPGA design store.

 

For further information, you may refer to website below:

您的意思是说,我这个开发板上的E-tile模块可以使用QSFPDD 400G光模块传输是吗?但我在使用 Agile E-tile Transceiver Native PHY IP进行外部回环测试时,接收端一直没有接收到数据。是我哪里配置有问题还是这个开发板上的E-tile模块不可以使用QSFPDD 400G光模块传输?

Hi wang5,

 

Please use e-tile channel placement tool to check whether your placement is correct anot.

您好,我这个开发板上的每个QSFPDD模块只有8个通道,而这个E-tile-channel-placement-tool好像是以12个通道进行设计的。我的通道的放置好像和工具的不太一样,我的通道放置应该在表格的6个通道基础上加入通道6与通道7。我帮我的代码发给您,麻烦您帮忙给看一下

Hi wang5,

 

May I know that is there any issue when you doing the testing on internal loopback?

在执行内循环测试的时候,接收端可以正常接收到数据,接收到的数据看起来也是正常的;有问题的地方在于,刚下载程序后,没有内循环,外部也没有接入信号,但是接收端也会是不是的出现数据,不知道因为什么原因?

Hi wang5,

 

It seems not the board issue. I would suggest you to do the testing on the optical module.

光模块已经测试过了,可以正常使用。测试方法是:使用另一个带有F-tile的开发板,然后用F-tile Ethernet intel FPGA hard IP搭建出一套400G传输网络进行测试。一开始测试没有成功,因为外部采用的是环回测试。然后更改了一下IP的配置,可以进行正常的信号传输。

Hi wang5,


Is there any update from your side?

还是不行,我感觉是IP核的某些配置没有设置好或者是这个开发板不支持这个400G的光模块。导致其无法进行信号传输。
