Problem with DMA Controller in Qsys

I am trying to add a DMA Controller in Qsys in Quartus Prime 16.1 but during generating the VHDL code it fails due to the following error: Can anyone advise how to resolve this? Thanks!

Hi KTan,

Thanks for your response. I can try switching to 18.1 and see if it will be fixed.

Before then, I played with different parameters and noticed that when I decrease the size of on-chip-memory to 16384 bytes or lower, qsys generates the VHDL code successfuly. I am attaching a screenshot of the qsys (it is very simple). The device is MAX10: 10M08SAE144C8GES. I switched the device to MAX10: 10M16SAU169C8G and it was the same; QSYS compiles for on-chip memory size of 16384 bytes and fail for larger. The error is same as above. Do you have any insight on why it happens?
