For guidelines on BUFGCTRL locations for USRCLKs generated via Fabric PLLs/MMCMs, refer to the attached Microsoft Word and Excel documents.
For BUFG_LB locations for TXUSRCLK/TXOUTCLKs and RXUSRCLK/RXOUTCLKs, refer to the tables below.
Please ensure in the Vivado tools that the correct BUFG_LB locations are used as per these tables.
This information will be added to the 7 Series GTZ Advance Specification User Guide (UG478).
