LogiCORE 10-Gigabit Ethernet MAC - Vivado - In WAN mode, marginal timing has been seen when targeting Artix-7 devices

Description

If using 10-Gigabit Ethernet MAC core generated with WAN mode, marginal timing has been seen when targeting Artix-7 devices.

Solution

If small timing failures occur, changing some Vivado Synthesis and Implementation tool options has been seen to result in the timing passing. 

Some possible options are:

  • In Implementation Settings, under Place Design, set the directive to "ExtraPostPlacementOpt".
  • In Implementation Settings, enable "phys_opt_design".
  • In Synthesis Settings, change the "control_set_opt_threshold" to 60.
