Read from a register that does not have all 0s as a default to verify that the interface is functional. Output s_axi_arready asserts when the read address is valid, and output s_axi_rvalid asserts when the read data/response is valid. If the interface is unresponsive, ensure that the following conditions are met:

  • The s_axi_aclk and aclk inputs are connected and toggling.
  • The interface is not being held in reset, and s_axi_areset is an active-Low reset.
  • The interface is enabled, and s_axi_aclken is active-High (if used).
  • The main subsystem clocks are toggling and that the enables are also asserted.
  • Add AXI4-Lite interface to ILA, and analysis data captured when triggering at s_axi_rvalid.
