I’m have a major issue with Quartus and their LVDS interface for the Arria 10. I’m trying to use an external PLL to drive both RX and TX LVDS channels and am getting this error message: "error_message" : "matched_atom == 0".

[GZsch]

This happens on standard version 17.1, 18.1.1, and prime version 19.3.

Hi Gregory,

Can you show me the full error message? Also, have you selected to use external PLL in the LVDS IP?

Thank You.

Hi Greg,

Can you send me your design via private message? Its very hard to debug as i am not visible to the design.

Thank You
