The generate process/procedure can be passed the ID of the FIFO and then the information pushed into the FIFO.

The ID of the FIFO is much like a constant. It is being used as a reference into the data structure. The information is then pushed into the data structure. No pesky driver issues at all.

Looking forward the long term…[Read more]

I am using the AXI memory model. I think it is all working as it should. I actually tried using the ‘-‘ in the scoreboard data for the inactive bytes. I then used check() and it worked well.
Thanks
Jon

Which OSVVM VC are you using?

For AXI4 Manager, it writes a U to memory in locations when WSTRB is 0. The U will not be stored in memory. For reading, there is no indication the data is valid or not. Hence, if your burst FIFO is organized as words, you will need to exclude those bits from comparing to X”020100–“. The ‘-‘ is…[Read more]
