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 KTan9,

In the qsys file uploaded above, the SRAM memory size is 16384 bytes which I can compile too but when you increase the SRAM it fails.

In general, when the SRAM is set to a 2^n values larger than 64 (64, 128, 256,...) , it generates HDL code successfuly but it fails otherwise. For example if I set it to 20,480, it fails but if I set it to 32,768 (2^15) it succeeds
