generate coe file

For what purpose are you using the code...? I'm not sure about others,but I used it as the co-efficient file for storing the BRAM contents with specific addr. Instead of loading memory editor each time,I loaded the contents addr and data myself accordingly,but never got any error....It's just a coe file.No idea about .mif anyway.Someone else might have a better vision,let's see

how to generate a .coe file

hai,
is it possible to load directly the .mif file?..
the .coe file is also the same as .mif file, just loading the memory with some values initially.
in the xilinx core gen, while generating the BRAM in the final stage we have an option to load the .coe file,
if we can load .mif file, plz explain how we can do it?

Description

Keywords: FIR filters, memory, RAM, ROM, distributed, block

Urgency: Standard

General Description:
What is the role of COE and MIF files for memory cores?
Solution
For all new cores released in the 3.1i design tools, as well as in all new IP going forward, the following restrictions apply to COE and MIF files:

1. Only COE files may be used as inputs to cores for the purpose of specifying initialization values for memory cores and for specifying coefficient values for filters.

2. MIF files can only be generated as output files for use in HDL behavioral simulations. They cannot be used to specify initial values when a core is generated.

MIF files will always be written out for memory and filter cores (in binary format only), based on values specified in any input COE files (or default values, as the case may be).

- For an example COE file, please see the data sheet provided with the core.

- If you need to add a comment line in the ".coe" file, use ";" at the beginning of the line.

.coe file comments

Hi,
Its correct that you can only upload ".coe file" for RAM/ROM in core generator. If you have ".mif file" or hex file you can convert it to ".coe file" and then use it.
