Any request to the bus for PCIe (except for a posted Memory write) requires a completion TLP to complete the associated AXI request. The Slave side of the Bridge checks the received completion TLPs for errors and checks for completion TLPs that are never returned (Completion Timeout). Each of the completion TLP error types are discussed in the subsequent sections.
