Avalon-MM with DMA txs signal_tap
Interface type is Avalon-MM
Avalon-MM txs signal_tap
Why is txs_waitrequest_o l pulled down 160 clocks apart when Interface type setting Avalon-MM with DMA?
This question has puzzled me for several days.
I want to know if the signal is correct.
I need someone who can help me, thanks a lot.
