Modify Pop Word to handle more than a Byte

[Jeremy]

Hi Jim. Pop word has been a great asset for me while creating test cases. I recently ran into an issue while using it when my data width size was not a byte. I made local updates to fix this and was hoping you could incorporate this in one of the next updates.

In my update I replaced 8 with Data’length and replaced 7 with the constant DataLeft.

Procedure PopWord can be found in the file FifoFillPkg_slv.vhd.

Hi Jeremy
What are you trying to do? I think I am miss understanding something.

The intent of PopWord is to pop a data’length sized word from a byte oriented FIFO and for the first word, adjust the number of bytes assembled in a coordinated fashion with the ByteAddress.

The pop (procedure and function) that is part of the Scoreboard/FIFO API will pop an item from the FIFO that matches the size of the item when it was pushed.

Best Regards,
Jim

Aah I see. Yes what I was doing was overkill. Thank you. The pop procedure is sufficient for what I need to do.
