Inferring a True Dual Port RAM with Byte enable for MAX10 FPGA

I'm trying to implement a True Dual Port RAM with byteenable for MAX10 FPGA. When I try synthesizing the code it gets inferred as an SYNC_RAM (RTL Viewer) but without byte enable as one of its ports....

    Hi,


    The reason why there are 4 M9K blocks is because of mem_byte0, mem_byte1, mem_byte2 and mem_byte3 you declared.

    May go to Edit -> Insert Template -> Verilog HDL -> Full Designs ->RAMs and ROMs and refer to True Dual Port RAM (dual clocks).

    May also go to Edit -> Insert Template -> VHDL -> Full Designs ->RAMs and ROMs and refer to Byte-enabled True Dual Port RAM for byte enable. (VHDL)


    Thanks,

    Best regards,

    Sheng

Hi Sheng,

Thanks for your remark. I was able to manage it with a single memory block after referring to the templates.
