To verify that the interface is functional, try reading from a register that does
not have all 0s as its default value. 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
aclkinputs are connected and toggling.
- The interface is not being held in reset, and
s_axi_aresetis an active-Low reset.
- The interface is enabled, and
s_axi_aclkenis active-High (if used).
- The main core clocks are toggling and that the enables are also asserted.
