What is the meaning of the following critical warning?
How do I resolve it?
This warning states that the external reset used in the block design has not been related to the clock of an interface that is using it.
In other words, the block design must be told which clocks a reset is synchronous to.
To relate a reset to the clock, the ASSOCIATED_RESET parameter of a clock interface should be set to the external reset name.
This can be performed in the GUI by double-clicking on the clock interface port, and setting the Associated Reset parameter.
Additional resets can be delimited by colons.
For example, to perform the change via TCL for a reset interface ARESETN to be related to clock interface M_AXI_GP0_ACLK , the following command can be used:
set_property CONFIG.ASSOCIATED_RESET ARESETN [get_bd_ports M_AXI_GP0_ACLK]
