3.13.5.1. AMBA* 4 AXI-Lite Slave Requirements

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