LogiCORE IP Ten Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) v2.6, 7 Series, Vivado - Slack Violations sometimes occur on short paths

描述

Timing errors sometimes occur on short paths between GT and the core in the Vivado 2012.4 tools with the 10GBASE-R/KR core.

解决方案

When slack violations are reported during implementation on paths which should normally meet timing (i.e., comprising only a few levels of logic), enter the command below in the Tcl console and re-run implementation.
