Description

Known Issue: v1.2 

When I am in x8 Gen 2 mode, I occasionally see a trn_reof_n assertion without an associated trn_rsof_n assertion.

Solution

The issue occurs when the block receives back-to-back TLPs and a packet is being written into the FIFO at the same time.

Further, you would have to deassert trn_rdst_rdy_n during this time. 

It is recommended that you ignore trn_reof_n assertions that do not have an associated trn_rsof_n assertion. 

A solution is being investigated for this problem.
