Query on AVMM protocol

What happens to the Avalon MM transaction initiated by master when slave asserts its waitrequest signal high forever. Will transaction be timed out or any other phenomena will take place?

Hi Nagaraju,


If the waitrequest signal is high(asserted) forever, there will be NO transaction occur. The cycle becomes a wait-state. address, read, write, and byteenable remain constant. The transfers ONLY complete on the rising edge of the first clk after the slave interface (low) deasserts waitrequest signal.


Thanks,

Regards
