用KC705做jesd204協(xié)議的時(shí)候報(bào)下面的錯(cuò)，該怎么解決呢？?

[Place 30-140] Unroutable Placement! A GTXE_COMMON / GTXE_CHANNEL clock component pair is not placed in a routable site pair. The GTXE_COMMON component can use the dedicated path between the GTXE_COMMON and the GTXE_CHANNEL if both are placed in the same clock region. If this sub optimal condition is acceptable for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING. However, the use of this override is highly discouraged. These examples can be used directly in the .xdc file to override this clock rule.

解決辦法：

卡了好久終于解決，這里只是提供下思路吧，畢竟每個(gè)人都不一樣

1、我是因?yàn)樗膫€(gè)時(shí)鐘共用一個(gè)，參考下面鏈接辦法，沒有解決，最后將時(shí)鐘改成一個(gè)，問題解決，下面鏈接說明了具體的原因。

2、用專用7系列傳輸核來做

7系列開發(fā)板有專用的傳輸核，這里給個(gè)鏈接你自己參考去產(chǎn)生，這里支持很多協(xié)議的傳輸，我用的是jesd204。
