收发器接收pin作为收发器的参考钟

1SM21BEU2F55E2VG，quartus pro 19.3 根据收发器的user guide说明，GXT的数据管脚可以作为别的收发器的参考钟 我们的需求是这样，在一个 H tile中，24个收发器，8个输入参考钟 现在8个输入参考钟已经都占用了，还需要额外的4个参考钟，根据手册看到GXT的RX Pin0.. RX Pin 5可以作为输入参考钟，但是我们编译的时候 发现编译无法通过

HI,

I have tried with duplex design, reduce data rate and also disable GCB but still failed with fitter error.

I will file an investigation report to Intel Engineering team to look into this issue.

Thanks.

Regards,

Deshi
