    Hi YL

    Thanks for the quick reply

    Doing that, we go outside of the address span : Quartus gives the span 0x04000000 and Quartus normally gives 32 bit Word address, so in byte address, the span is 0x10000000 (yes in HEX).

    master_write_32 $mp 0x00ABCDEF 0x20000000 will write OUTSIDE of this span.

    So it wont work.
