Read from a register that does not have all 0s as a default to verify that
the interface is functional. Output
when the read address is valid, and output
asserts when the read data/response is valid. If the interface is unresponsive, ensure that
the following conditions are met:
S_AXI_ACLKinput is connected and toggling.
- The interface is not being held in reset, and
S_AXI_ARESETNis an active-Low reset
- If the simulation has been run, verify in simulation and/or a debug feature capture that the waveform is correct for accessing the AXI4-Lite interface.
