3D RAM memory support

Hello. We are currently using Intel Arria 10 FPGA for our projects. For designing and programming it we have Quartus Prime Pro v21.1.0 Build 169. Does it support 3D memory technology and >=64GB ...

Hi Mark,

Yes. 3D RAM is supported. In Text Editor, you may go to Insert Template -> SystemVerilog -> Full Designs -> RAMs and ROMS to check on 3D RAM template. Below attached one of the ram template (check pic).

The maximum memory bits supported is not larger than 2**31 (2147483648) bits. Also, the largest device memory bits only until 271810560 bits. >=64GB RAM memories I think you mean external memory.

Error(22123): Netlist error at mixed_width_ram.sv(27): ram 'ram' with size larger than 2**31 bits is not supported for blasting

Thanks,

Best Regards,

Sheng

Hello Sheng,

I am newbie in developing systems using FPGA and Quartus Prime software. Therefore, it would be nice to have an example project with included 3D RAM as EMIF.

Could you also explain a bit more the limitation of RAM by 2**31 bits?

Best regards,

Mark
