Efficiently Populating .mif File

Altera_Forum · ‎06-11-2010

Hi, this is my first post so I hope it is in the right section. I want to populate a .mif file with samples corresponding to one complete cycle of a sine wave. I generate the samples in matlab. At the moment I have 256 samples and I initially just wrote them into the .mif manually. Clearly this is rather tedious and will become more so since I want to include many more samples. Does anyone know of a more efficient means of achieving this?

Use Matlab to wite mif:

fid = fopen('filename.mif','w');

fprintf(fid,'--MIF data generated by MATLAB\n');

fprintf(fid,'--Date: %s \n\n', date);

fprintf(fid,'WIDTH=16;\n');

fprintf(fid,'DEPTH=256;\n');

fprintf(fid,'ADDRESS_RADIX=UNS;\n');

fprintf(fid,'DATA_RADIX=DEC;\n');

fprintf(fid,'CONTENT BEGIN\n');

for k = 1:256

fprintf(fid,'%i : %i;\n',k-1,data(k));

end

fprintf(fid,'END;');

fclose(fid);

*****************

you can also copy a column and paste to MIF in Quartus
