5.10.2.1. Bufferable

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

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

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