6.14.6.1. AMBA* 4 AXI-Lite Subordinate Requirements

For an AMBA* 4 AXI-Lite subordinate side, the host or manager can be any interface type, such as an Avalon® (with bursting), AMBA* 3 AXI, or AMBA* 4 AXI. Platform Designer allows the following connections and inserts adapters, if needed.

  • Burst adapter Avalon® and AMBA* 3 AXI and AMBA* 4 AXI bursting host or manager require a burst adapter to shorten the burst length to 1 before sending a transaction to an AMBA* 4 AXI-Lite subordinate.
  • Platform Designer interconnect uses a width adapter for mismatched data widths.
  • Platform Designer interconnect performs ID reflection inside the subordinate agent.
  • An AMBA* 4 AXI-Lite subordinate must have an address width of at least 12-bits.
  • AMBA* 4 AXI-Lite does not have the AXSIZE parameter. Narrow manager to a wide AMBA* 4 AXI-Lite subordinate is not supported. For managers that support narrow-sized bursts, for example, AMBA* 3 AXI and AMBA* 4 AXI, a burst to an AMBA* 4 AXI-Lite subordinate must have a burst size equal to or greater than the subordinate's burst size.
