你好,
当我想在内部将TEMAC连接到1000BASE-X时,我有一些关于tx_elastic_buffer,gmii_tx_clk和gmii_rx_clk的问题。 关于IODELAY和OBUFT以及IBUF我知道我应该删除它们因为内部连接不需要IODELAY。 Abouttx_elastic_buffer,基于pg047它仅用于数据来自Input PAD时的数据同步。 关于内部MAC连接可以将其删除吗? 现在关于gmii_tx_clk,这是1000BASE-X的输入。 在1000BASE-X中,gmii_tx_clk只是连接到IODELAYs和TX_elastic_buffer的相关信号。 因为我不需要它们(我也不确定tx_elastic_buffer)我想我可以忽略或删除它。 我对吗? 关于gmii_rx_clk,它刚刚连接到OPAD。 我想我也可以删除它。 你能指导一下这些信号。 问候 以上来自于谷歌翻译 以下为原文 Hello, I've some question about tx_elastic_buffer,gmii_tx_clk and gmii_rx_clk when I want to coonect a TEMAC internally to 1000BASE-X. About IODELAY and OBUFT and IBUF I know that I should remove them because internal connection doesn't need IODELAY. About tx_elastic_buffer, based on pg047 It's just for data synchronization when data comes from Input PAD. About Internal MAC connection Can I remove it? Now about gmii_tx_clk,That is input to 1000BASE-X. In 1000BASE-X, gmii_tx_clk just connected to related signals to IODELAYs and TX_elastic_buffer. So because I don't need them (also I'm not sure about tx_elastic_buffer) I think I can ignore or remove it. AM I right? And about gmii_rx_clk, that just connected to OPAD. I think I can remove it, too. Could you please guide me about these signals. Regards |

嗨Huppa,
当内部连接到TEMAC时,以下链接中讨论的内容也适用于1000Base_X内核。 http://forums.xilinx.com/t5/General-Technical-Discussion/Tri-mode-Ethernet-MAC-with-Internal-PHY-interface/m-p/486850#M19280 不需要IODELAY,IOB或弹性缓冲区,两个核心应直接通过GMII接口连接,如下图所示。 问候,萨蒂什----------------------------------------------- --- --------------------------------------------请注意 - 如果提供的信息有用,请将答案标记为“接受为解决方案”。给予您认为有用的帖子。感谢.-- ---------------------------- --------------------- ---------------------- 在原帖中查看解决方案 以上来自于谷歌翻译 以下为原文 Hi Huppa, The same things as discussed in the below link apply to 1000Base_X core as well when internally connected to TEMAC. http://forums.xilinx.com/t5/General-Technical-Discussion/Tri-mode-Ethernet-MAC-with-Internal-PHY-interface/m-p/486850#M19280 There is no need of IODELAY,IOB's or the elastic buffer and the two cores should be connected directly through the GMII interface as shown in below snapshot.
