You are designing a low-power IoT peripheral using AXI4-Lite. To save area, you decide to remove the WSTRB (Write Strobe) signal. What is the functional impact of this decision?
Per the AMBA AXI4 specification, WSTRB is a mandatory signal even in AXI4-Lite. It allows the master to signal which byte lanes contain valid data. Removing it would make the interface non-compliant and prevent the slave from distinguishing between valid data and bus noise on partial-word writes.
