AXI WRITE DATA CHANNEL

Muthu_venkatesh

Hi All,

                       I am doing single write operation to AXI slave from avalon BFM. The data and address signals

are reached into the axi slave.But if i am try to read back the data which i have written in the same location,the data is  not matched.

It means the data is not written.

Below i attached one image.In that  Valid Data;66 ,Valid Address:0. In Data channel  the WLAST  signal is low when i am sending the valid

data.Is it correct or wrong.

                    Please anyone help me to solve this issue.

                    I

Thanks

    Hi ,

                          Thanks for your guidance. Sry for late reply.I fixed that issue.

    The reason for the issue is byte enable signal in avalon bfm. I need to enable all 256 bit  in master side .

    I enabled 128 bit because of that the altera interconnect is not properly generate the axi signal (avalon to axi signal conversion error).

    Thanks
