LogiCORE IP Ten Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) v2.4, 7 Series - Block lock FSM requires one extra good/bad code
Description
The IEEE block lock state machine requires 64 good blocks before block lock is set, and 16 bad blocks before it resets.
The Ten Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) v2.4 currently requires 65 good blocks before block lock is set, and 17 bad blocks before it is reset.
Solution
In the Ten Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) v2.5, the core has been updated to follow the specification and require 64 good blocks before block lock is set, and 16 bad blocks before it resets.
