Hello!

There is a problem with this IP which is asynchronous :
for example

"always @(state or rx_valid or rx_active or rx_err or pid_ACK or pid_TOKEN
or pid_DATA)
begin .....
"

I think it's possible to change this part of the code by testing these
conditions on a falling edge of the clock...
Maybe I'm totally wrong...

Thanks for your help.
Best regards

David Bennetot
