1.3.1.1.2. Extended Multiblock Alignment (EMBA)

Table 2.  EMBA Test Cases
Test Case Objective Description Passing Criteria
EMBA.1 Check if 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_int
  • The j204c_rx_emb_lock is asserted after assertion of j204c_rx_sh_lock.
  • The j204c_rx_int signal should stay low if there is no error.
EMBA.2 Check if extended multiblock lock status is 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

The rxlink_clk is used as the sampling clock for the Signal Tap.

  • The j204c_rx_emb_lock should remain asserted. 3
  • The j204c_rx_int signal should stay low 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

The rxlink_clk is used as the sampling clock for the Signal Tap.

  • 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 should stay low if there is no error.
3 The j204c_rx_emb_lock signal should remain asserted after 12 hours.
