Critical Issue
Description
User logic must hold the 50G Interlaken IP core itx_chan
signal
steady for the duration of the packet on the TX user data transfer
interface, from the time user logic asserts the itx_sop
signal
through the cycle in which it asserts the itx_eop
signal.
Resolution
This issue has no workaround. User logic must ensure that
the itx_chan
signal behaves as described.
This issue is fixed in version 13.1 of the 50G Interlaken MegaCore function.
