Hi-

Tools, Quartus 18.1

In Internal Memory (RAM and ROM) User Guide.pdf, <-FPGA

words is 16bit or 32bit?

Thinks

  • That will be 8-bit words of memory.

    You can see this by opening the RAM IP in the IP catalog. Once the IP parameter editor GUI open, you will see "How many 8-bit words of memory?".

      Hi Richard Tan

      I have changed job

      I received previous project(Quartus 18.1)

      The original engineer retired from the company.

      In following figure,

      It says "262144 words."

      You say words is 8 bit

      So 40 x 8 x 262144 = 83,886,080

      Is this memory 83,886,080 bits?

      Hi Richard Tan

      Arrir 10

      Thanks!

  • Let me rephrase my previous reply. By default , the bit of memory is set as 8 when you open the IP and you can change the number of bits in the 'q' output width.

    Referring to the screenshot that you attached, you are setting 40 bits with 262144 words.

    So the total memory bits will be 40 x 262144 = 10,485,760. You can verify it by checking compilation report. Fitter > Resource Usage Summary.
