5.10.2.1. Bufferable

Platform Designer interconnect treats AXI transactions as non-bufferable. All responses must come from the terminal slave.

When connecting to Avalon® memory mapped slaves, since they do not have write responses, the following exceptions apply:

  • For Avalon® memory mapped slaves, the write response are generated by the slave agent once the write transaction is accepted by the slave. The following limitation exists for an Avalon® bridge:
  • For an Avalon® bridge, the response is generated before the write reaches the endpoint; users must be aware of this limitation and avoid multiple paths past the bridge to any endpoint slave, or only perform bufferable transactions to an Avalon® bridge.
