set_false_path -from [get_clocks {rx_clkout_enh}] -to
[get_registers <Core Logic A>]
Based on how the clocks are connected in the design, you may have to include
additional constraints to set false paths from the registers in the core logic to the
clocks.
•
set_false_path -from [get_clocks {tx_clkout}] -to
[get_registers <Core Logic B>]
Based on how the clocks are connected in the design, you may have to include
additional constraints to set false paths from the registers in the core logic to the
clocks.
•
set_false_path -from [get_clocks {rx_clkout}] -to
[get_registers <Core Logic B>]
Based on how the clocks are connected in the design, you may have to include
additional constraints to set false paths from the registers in the core logic to the
clocks.
Note: If any of the profile or configuration switch involves switching from FIFO to
For example, if the base configuration of the above case is configured for the TX and
RX FIFOs in the Register Mode, the following constraint needs to be created:

6.18. Unsupported Features

The following features are not supported by either the Transceiver Native PHY IP core
or the PLL IP reconfiguration interface:
Send Feedback
the register mode, then the false paths should be set between the PCS-PMA
interface register and the core logic because the common clock point is
within the PCS-PMA interface.
