In Arria 10 , I use PCIE + mSGDMA ，when PCIE_HIP setting the interface type is Avalon-MM with DMA，the txs_waitrequest_o There will be the following performance.
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.
