Hi,

You better use a program to write the mif files as copy/paste is suitable for small size data.

Here is an example

Using Matlab to write 256 signed data to 16 bit 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);
