1.4.1.2. Extended Multiblock Alignment

Table 2.  Extended Multiblock Alignment Test Cases
Test Case Objective Description Passing Criteria
EMBA.1 Check if the Extended Multiblock Lock is asserted only after the assertion of Sync Header Lock. The following signals in <ip_variant_name> _base.v are tapped:
  • j204c_rx_emb_lock
  • j204c_rx_sh_lock
  • j204c_rx_int 2
  • The j204c_rx_emb_lock is asserted after assertion of j204c_rx_sh_lock
  • The j204c_rx_int signal is deasserted if there is no error.
EMBA.2 Check if the Extended Multiblock Lock status being stable (after extended multiblock lock or until elastic buffer is released) along with no invalid multiblock. The following signals in <ip_variant_name> _base.v are tapped:
  • j204c_rx_emb_lock
  • j204c_rx_int 2
  • The j204c_rx_emb_lock should remain asserted.
  • The j204c_rx_int signal is deasserted if there is no error.
EMBA.3 Check the lane alignment. The following signals in <ip_variant_name> _base.v are tapped:
  • j204c_rx_dev_lane_align
  • j204c_rx_int 2
  • The j204c_rx_dev_lane_align is asserted after the assertion of j204c_rx_emb_lock and next LEMC event.
  • The j204c_rx_int signal is deasserted if there is no error.
2 The error interrupts that are enabled by default is sufficient for passing criteria.
