how to convert .txt to .coe file

Hai all;

I try to do some tutorial about create a ram using coregen in xilinx. I follow the steps listed in the pdf file (I get from google). However, I didn't have the .coe file and I try to create my own .coe file. My question is how to create .coe file? And if possible, how to convert a .txt file to .coe file? Maybe this is a simple question, but I have try to search and try simple tutorial,but I not get the right way. Need helps from expert. Thanks in advance.

A .coe file is just a list of the memory contents with a simple header.

For example:


If you data is decimal , make the radix 10, and if it is hex, use a radix of 16.

If the amount of data is small, just hand edit your text file. If if is large, you would usually write a Perl script or similar to modify the text file.

Code:

 memory_initialization_radix = 2;
 memory_initialization_vector = 
 1111111111111111100000000000001000,
 1111111111111111100000000000011001,
 1111111111111111100000000000101010,
 1111111111111111100000000000111011,

Hai rberek,

Can I write the list of memory contents with a simple header in notepad? How to save it by .coe? Or there is any free software to create .coe file? Thanks for reply

The special free software you need is a text editor ;-). Just save it as a .coe file. Or rename it to a .coe file after you save it. Either way will work.
