Quartus 15.1 issue for altsyncram

It's exactly what it says. You can't use that type of ram block in the Arria 10. FPGA development is not like software where you can just bring in any code that will fit. Your FPGA consists of various types of hardware. Other types of FPGA consist of different hardware. They both may be ram blocks but that doesn't mean they can be used in a given FPGA. You can infer memory by carefully writing your HDL code so that Quartus will use the available memory resources. Another way to get a memory block is to use the IP catalog to create a module containing the memory you need.
