Axi4Demo Design

This example (axi4Demo directory) performs a write and read test for the internal BRAM that is attached to an AXI interface. First, the software writes to the internal BRAM through the AXI interface. Next, it reads back the data and compares it to the expected value. If the data is correct, the software writes Passed to a UART terminal

The AXI bus interrupt pin triggers a software interrupt when write data to the AXI bus is 0xABCD. The design displays these messages in a UART terminal:

axi4 master demo !
Passed!
axi4 master interrupt demo !
Entered AXI Interrupt Routine, Passed!
