Re: [pci] why the address are grey coded?

Hi!

 

Do you have an idea what the testcase should be for the bug you found in the fifo?

I would like to add a testcase for every bug that is found in the design, so it doesn't happen again!

 

Regards,

Miha Dolenc

The addresses are grey coded because it's an asynchronous fifo design.
Normal binary counter comparison is only good for synchronous fifo designs.

Actually this async fifo isn't quite correct in your open core.  We are fixing now and will update you in a day or so.
