Hi,

  • Byte (8-bit), halfword (16-bit), word (32-bit), doubleword (64-bit) or quadword (128-bit)

those are transfer type, there is no option to change width.


i want to know on which version you did those changes?

Hi,

I used to use 21.3 to generate 128width.

"there is no option to change width" ---- I think it is not reasonable since the performance is too much low with 8 bit width.
