LogiCORE IP Ten Gigabit Ethernet PCS/PMA (10GBASE-R) v2.1 - Occasional timing errors seen when targeting 7 Series Devices
描述
When I target a Virtex-7 or Kintex-7 device with the LogiCORE IP Ten Gigabit Ethernet PCS/PMA (10GBASE-R) v2.1 Core, timing errors that result in the design not meeting timing occur in TRCE.
解决方案
To work around this problem, re-run MAP with option '-t <n>'; where n > 1 (use a cost table other than the default of 1).
