Any time there is more than one transaction ID (issued by one or more master devices) on which multiple outstanding transactions can be issued, and there is more than one connected slave device that can queue multiple transactions, and any of the slave devices can respond out-of-order on either the R or B channel, there is a potential cyclic dependency (deadlock) risk. Because the AXI Crossbar core is fully AXI-compliant, the AXI Crossbar core is equipped to handle slave devices that support out-of-order response.
