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,

For a start, below AN778 is a good doc to learn about L-tile/H-tile architecture and pin placement guide.

Now, in order for me to help you debug your issue better, pls share with me your Quartus design QAR file

  • So that I can analyze what's the failure error about ? Is it synthesis or fitter error ?
  • Also I need to review your transceiver design pin placement and connection as different IP may has its own pin placement restriction guideline

Thanks.

Regards,
