I think the following thread might help you.
$readmemh("mem_init_vlog.mif", mem, 0, 255); is not the synthesizable statement while .coe is Wow, cherry pick statements and claim I'm suggesting the above? So why did you point this out like I was suggesting to use this?. FYI, In some instances readmemh is synthesizable just look at both xilinx's and Altera's synthe
I think what you are looking for is happens to point to the old version but you can find the newer version of the document on Xil
I have to initialize multiple instances of same BRAM using different .coe files. But i havent find a way to do that yet as xilinx initialize all the instances with the sane .coe file. How do I solve this issue
i am working on image processing using xilinx 14.2. i have used IP core, block ROM to store .coe file of images. i have added two i want to convert the obtained result into image. i have used Isim simulator. please guide me.... which file i need to use so that i can convert it in image? do anyone have the matlab code for conversion? p
If you look in the xilinx documentation it very clearly explains the format of the coe file. It should be something like this: memory_initialization_radix=16; memory_initialization_vector =0000, 0003, 0006, 0009, 000C, 000F, 0012, 0015, 0019, 001C, 001F;
hi. please tell me how to convert image to .coe file . am using it for xilinx. is this using matlab or any direct procedure is there using xilinx ise.
No I will not. I will however suggest googling on something like "xilinx read .coe file format vhdl" because the information on how to do that is absolutely trivial to find on this here fine internet.
Use the RAM to load your program. Some mapping has to be done. I haven't tried this in xilinx, only Altera.
hii buddies., recently i started working with FPGA and VHDL coding. Im using .coe file and initializing Block single port ROM ip-core generator in xilinx 12.4 and 13.4 xilinx Fpga prototype tool. Taken Top module code and copied that core gen component and your instance device names, and wrote test bench, and my .coe (...)
Platform : xilinx Virtex II Pro Board Software : xilinx ISE I generated a BRAM (Width : 4; Depth : 16) using IP Core Generator and initialised it using a .coe file. 4-bit address mapped to 4 switches on board. 4-bit data mapped to 4 LEDs on board. When I input the binary values (0000 to 1111) in a sequence(ascending/descending) (...)
hi friends I have tried a lot for syntesizing verilog code obtained using fdatool, pls anyone can tell me how we can syntesize the code in xilinx or altera
hi every one I generated coefficients in matlab for low pass filter and then i use it in xilinx core 5. after I generate the code and pass it to FPGA it doesn`t work!!!!!!!!!!!!!!! input is 16 bit and output must be 16 bit because my DAC is 16 bit. please help me. I attached core pictures. regards
Hi all, I'm using the xilinx BRAM CORE GEN to develop project on LDPC DECODER... I would like to ask if anyone knows how i can store external files(.coe file) so that my Verilog program can access the content of the file during run time. i need to access the content of the memory one by one, such as reading data line by line from the memory. P
xilinx -coe file specifies the contents for a block Post added at 14:35 ---------- Previous post was at 14:28 ---------- real is not synthesizable
how to initialise real values (eg:3.456) in blockram using core generator......
what does this file extension actually mean? '.coe'
Is there any solution to convert .bit to .coe file ? I have to initialise a single port RAM (create with Block Memory Generator) with a bitstream in a FPGA virtex5 (xilinx) So, I'm looking for any soft to convert my .bit file. I try to convert it to .hex file with BIN2HEX.EXE available here : File
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
Dear Hoda, I assume you want to store an image in a BRAM...first you can use matlab to obtain the pixels value of the pictures as 0's and 1's. Then you have to write a .coe file, thats a normal text file and you write the values in a certain way to be able to feed it to the BRAM later and save the txt file as .coe. Please check [URL="www.
Hello guys... Im dng my engineering final year project on Real time Cellular Interference Suppression using FPGA...For this i have generated a code for band reject filter and the transfer function co-efficients .... I need to save these co-efficients into a .coe file so that i can make use of these in xilinx for implementation in FPGA....w
The easiest way for you to generate a ROM would be to use xilinx's Coregen tool, which is a part of the ISE design suite. It will create the VHDL code for you. xilinx uses .coe files to indicate the initial value of a memory. Examples of coe files can be found in the $xilinx/coregen/data directory, (...)

How to simple convert a .hex or .mif file from Altera to xilinx .coe file? Because I need to load a initial file into ROM (From IP Core Generate of ISE). Do you know any little software? Please help me! Thanks so much. :cry:
In fact, to generate xilinx coe file is to transform decade to binary of hex data. Matlab is very helpful. When using xilinx IP Core to generate RAM with initialization file or ROM with .coe file, the top two line is: MEMORY_INITIALIZATION_RADIX=2; MEMORY_INITIALIZATION_VECTOR=; // The radix here can 16 or 10 but if 10 (...)
Now i'm developing com-1000 board, i want to realize a FIR FILTER ad hoc. I'm using matlab for create a .coe file and xilinx ip core generator filter compiler v3.2 for implementing filter. I have write vhdl code for communicate with connectors J1,J2 etc, actmel micro controller and other componensts in the board, now i'm adding filter.xco created f
The rom is generated by core generator xilinx.
