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


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


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.
