Question for AXI responce when access error

Jun Usami

HI,

Does anyone know the minimum number of error responce (wready & rvalid) when AxLEN = 15?

Does it need to respond 16th? or we can respond 1 only?

Regards,

    Hi Koumoto-san,

    Thank you so much.

    Let me check the document.

    My slave has been response only once when it was operating both DECERR and SLVERR.

    -write : My slave didn't  check for enough asserted "WVALID" cycles, and it asserted BVALID before AXI master asserted WLAST.

    -read :  My slave asserted both RLAST and RVALID at next cycle of asserted RREADY.

    I should re-design  my AXI slave I/F.

    Regards,

    -GARO
