I think the key for you will be to determine the layout of your internal memory array. For reference I use an Intel i7 K 3. The following is the initial few lines from the MEM file I used: My recommendation at this time, is that if you can tolerate the performance degradation that occurs when LUT-based multiplexers are used to select the correct x 8 RAM, then use a x8 bit lane assignment. Approaching the Finish Line I am getting close to finishing my part of the project, and only have a week and a half left for this internship period. I have also used the SmartXplorer tool to find ways to keep project speeds maintained MHz in the past. In other words, the block RAMs in my current project can only be arranged in one form to provide the x 12 arrangement that I require, and I haven't determined if this arrangement is dictated by the synthesizer, or implemented by the placer.

With this MEM file, I could edit the baud rate field, data2mrm Bitgen, and download to my heart's content. I see why it is crashing now.

Bug in data2mem… | GPJtag

After several fruitless attempts. Initially I had left the tools to pick where to put it. I dtaa2mem seen enso's code in another thread on how 'lock-in' the location within dsta2mem Verilog Module for the 'ROM'. With this contortion made, I changed the baud rate constant and used Data2MEM to patch the bitstream by running Data2Mem from the command line: Rather than running Data2MEM from a command line, it is possible to set an option in BitGenand get BitGen to automatically run Data2Mem prior to the generation of its output bitstream file.

11- Initializing Block RAMs using DATA2MEM

In my case, the three block RAMs actually provide 6kB of storage. Data2MEM work in bytes. Another point I had overlooked: If I were Xilinx, I would have the placer perform this function instead of the synthesizer; too much FPGA-specific knowledge in the synthesizer probably has a negative impact on its portability across multiple FPGA families.

Users browsing this forum: For reference I use an Intel i7 K 3. If it is implemented in the placer, then the arrangement specified in the BMM file would likely be the mapping that the placer will use to set the geometry and arrangement of the block RAMs in the FPGA.

I think the key for you will be to determine the layout of your internal memory array. I did not understand how the blockRAM was organized. If you run into any difficulties, or find issues with the procedure I outlined, I'll be glad to give a hand. I am also working an odd schedule these days, but I'll try and respond to any questions or issues as quickly as I can. This site uses Akismet to reduce spam. The bytes are output in little endian form. Xilinx 7 series, Read more….

AR# i Data2MEM - How do I generate a ".mem" file from an ELF in data2mem?

Then insert some code into the ROM module? I don't think this code is causing the errors I currently see. Once that's done, you can hardware the bmm file and not worry about it again. Make sure to produce. Following the memory type declaration you have to define the address range in bytes represented by your block RAM memory. So when I truncate each line in the MEM file daat2mem three characters to represent each instruction wordthey represent only 1.

I am sure it will work for you.

Here is the command for this process data2mem -bm file. So I am again interested in trying to build the bridge to use data2mem for my project to cut down development times.

I have not found any information on this issue. Sat Jul 20, It is simply a name, or tag, that has no relation to the netlist. Page 1 of 3. If later on you changed your software without changing your design you can use the last command to update the bit stream without having to repeat this long process.
