Clarification on rx_st_empty Behavior for Unaligned Transfers (1 DWORD Length) in P-TILE :-

Hi thanavignesh,

My apology for the delayed response.

When the valid data is in rx_st_tdata[31:0] and the remaining data [255:32] is empty. The rx_st_empty_o will be 7 as the 7 dwords counted starting from the MSB are ignored.

The rx_st_tdata cannot be valid at rx_st_tdata[63:32] but not rx_st_tdata[31:0]. When the rx_st_empty_o is 6, the rx_st_tdata[63:0] should be valid. This applies for both read and write request.

The address alignment should be handled by user logic.

Thanks.

Best Regards,

Ven
