大家好
我正在构建一个基于Spartan6 LX45T的SDI视频系统。
我想知道我可以在一个GTP磁贴中实现每个通道的分离外部参考时钟。
我在一个GTP
tiLE中成功获得了lane0和lane1之间的案例共享参考时钟。
但我想让lane0和lane1根据自己的参考时钟单独工作。
结果，我在地图过程中遇到错误。
ISE显示BUFIO2是一个专用路由，只有一个选择。
据我所知，单通道SDI通道将刷新2个BUFIO2单元，因此一个GTP TILE与两个通道单独工作将需要总共4个BUFIO2。
不是吗？
到目前为止，虽然我启动了一个GTP TILE或两个GTP TILE，但我不能放置超过2个BUFIO2单元。
我怎样才能让四个通道作为自己的参考时钟。
需要很快帮助，非常感谢！

Hi, all
I am building a SDI video system base on Spartan6 LX45T. I want to know can i implement seperated external reference clock with each lane in one GTP tile. I have succeed for the case share reference clock between lane0 and lane1 within one one GTP TILE. But I want to let the lane0 and lane1 can be work seperatedly according their own reference clock. As a result, I am encountering error in map process. ISE show the BUFIO2 is a dedicated routing and have only one choice for its placement. As i know one lane SDI channel will comsum 2 BUFIO2 units, so one GTP TILE with two lane working seperately will need total 4 pcs BUFIO2. isn't it? By now, I can not place more than 2 BUFIO2 units although i initiate one GTP TILE or two GTP TILE. How can I let the four lanes act as their own reference clock. need soonly help, Thanks a lot!.
