Documentation AXI and AXI lite slave part did not work for me

[kuriousd]

Hi,

I implemented an AXI Slave based on the documentation:

from cocotbext.axi import AxiBus, AxiSlave, MemoryRegion

axi_slave = AxiSlave(AxiBus.from_prefix(dut, "m_axi"), dut.clk, dut.rst)
region = MemoryRegion(2**axi_slave.read_if.address_width)
axi_slave.target = region

However it did not work for me, the axi_slave target was None. I invoked AxiSlave function inside a class and I did:

from cocotbext.axi import AxiBus, AxiSlave, MemoryRegion

class Test():
   ....
   self.region = MemoryRegion(2**32)
   self.axi_slave = AxiSlave(AxiBus.from_prefix(dut, "m_axi"), dut.clk, dut.rst, target=self.region)

Maybe you want to consider this issue on the documentation.
