Is it possible to use $writememb in Quartus II?

[Altera_Forum]

Hi all. 

 I have a question about $writememb command in Verilog coding.  I can run $readmemb command without problem, but I can't get any output from $writememb command.  I have my code compilation passed without error, but the target file doesn't get anything written in it after run.   There are very few references on google and I am rather confused whether $writememb is a valid command in Quartus II. If it is, can anyone share the experience on how to use the command correctly?  Thanks.

$readmemb() works in a verilog initial block to set the initial contents of a block ram. This is valid in QuartusII to fill a register array (eg, block rams) with data at FPGA configuration time. It will work either in QuartusII (implementation) or modelsim (simulation). 

 However, $writememb() makes no sense in an FPGA implementation itself. Write the memory contents where? $writememb() would only be valid and useful in a test bench, not the FPGA itself. It does work in modelsim (simulation) as in a test bench context.

I see! Thank you ak6dn!  

Now I see what has gone wrong in my concept.  Thank you very much for the explanation. :)
