Extract text from Xilinx coefficient files (COE)
To convert COE coefficient files to another format, you need Xilinx Vivado or other Developer software.
To convert other file formats to the "Coefficient Data File" file type, you need software like Xilinx Vivado or a similar tool.
A .COE file is a Xilinx Coefficient file. Hardware engineers use it within Xilinx Vivado and older ISE software to initialize Block RAM (BRAM), ROM arrays, or to define tap coefficients for FIR filters in FPGA designs.
The format is highly restrictive and proprietary to the Xilinx ecosystem. It relies on a rigid ASCII text syntax requiring precise radix definitions (binary, decimal, or hexadecimal) and strict punctuation. One missing comma or a forgotten semicolon at the end of the file will crash the IP core generator. Furthermore, standard data analysis tools cannot natively process .COE files without custom text parsing.
Users frequently need to convert .COE files to CSV or TXT to analyze the raw data vectors in Microsoft Excel, Python, or MATLAB scripts. Alternatively, converting them to standard MEM or Intel HEX formats is common for broader hardware compatibility.
Because of its strict proprietary syntax, standard online converters fail to process this niche format.
Convert.Guru analyzes your COE file, detects the exact format, and lets you read the text inside.
Users also converted TLSCAN, JPG, TXT and PNG files.
If you want to convert COE file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Xilinx Vivado or similar software from the "FPGA Memory Initialization" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to COE, try Xilinx Vivado or another comparable tool in the "FPGA Memory Initialization" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our COE converter.
