What's the possible formats for initializing a memory core.I s there any scripts to generate some random binary data for an arbitrary Memory size
 

Sure, you can write script in MATLAB to do that.

Format for Xilinx coefficient file looks something like this:

memory_initialization_radix=2;

memory_initialization_vector=

00000000,
00000000,
00000000,
00000000,
00000000,
00000000,
00000000,
00000000;

Hope this helps

I have written a simple script to generate some random binary vectors for an arbitrary size memory.

The command Window output in matlab is perfect .but the coe file generated has some problem

any way can generate some random binary vectors to load as .coe file

Code: 
%Script to generate a .coe file for memory initialisation 
clc
fid=fopen('mem2.coe','wt');
x=0;
fprintf(fid,' %b',x);
d=input('Please enter depth of memory ');
w=input('Please enter the width of memory ');
range=power(2,w);
r=randint(1,d,range);
temp=dec2hex(r',(w/4));
fprintf(fid,';The data memory generated is \n ');
fprintf(fid,'MEMORY_INITIALIZATION_RADIX=16;\n ');
fprintf(fid,'MEMORY_INITIALIZATION_VECTOR= ');
d=d-2;
display('temporary-Assignment')
size(temp)
temp
for i=1:d-1
    fprintf(fid,'%d,\n',temp(i,:));
end 
fprintf(fid,';');
fclose(fid);
 

corrected code for .coe file generator script in matlab

Code: 
%Script to generate a .coe file for memory initialisation 
clc
fid=fopen('mem2.coe','wt');
x=0;
fprintf(fid,' %b',x);
d=input('Please enter depth of memory ');
w=input('Please enter the width of memory ');
range=power(2,w);
r=randint(1,d,range);
temp=dec2hex(r',(w/4));
fprintf(fid,';The data memory generated is \n ');
fprintf(fid,'MEMORY_INITIALIZATION_RADIX=16;\n ');
fprintf(fid,'MEMORY_INITIALIZATION_VECTOR= ');
d=d-2;
for i=1:d+1
    fprintf(fid,'%s,\n',temp(i,:));
end 
i=d+2;
fprintf(fid,'%s;',temp(i,:));
temp
fclose(fid);
