10 Gigabit Ethernet MAC v13.0 - Additional XDC constraints for the MDIO signal inputs to ease timing closure

描述

Additional false path constraints can be added to the MDIO logic to ease timing closure.

解决方案

Add this constraint:
# ignore the timing on the MDIO_IN signal as it is only sampled in the middle of a very large
# window.
set_false_path -to [get_cells core_name_core/xgmac_inst/G_MANAGEMENT.managen/mdio_master_i/mdio_in_reg_reg]

These have been added to the core XDC file in 2014.1.
