Its your design, learn to read code :)

Its likely that the component nios2_tb.nios2_inst.onchip_memory.the_altsyncram is dual-ported RAM, and you are generating addresses that are "out of bound!". Search the source code using a "find in files" tool (Textpad has one), and chances are you'll find it in the altsyncram component. Either way, you can probably probe the port A address of the altsyncram and see what addresses are being generated to cause the warning.
