Hi,
The project was created and compiled on both OS with the same "build.sh" script from generated Tcl. On Windows I used WSL to run the script.

Hello,

I apologize for the late reply. Do you have sample design by any chance?

Thank you.

    Hi,

    In design I have 6 identical LVDS SERDES IPs. Each LVDS SERDES IP drives 10 LVDS pairs. When I added individual external PLL for every LVDS SERDES IP, I could compile without any errors on both Linux Ubuntu 18.04 and Windows 10. Previously I had one common external PLL for all 6 LVDS SERDES IPs.

    Best regards
