- CRC algorithm HDL code generator (VHDL, Verilog, MyHDL)
- =======================================================
- `Homepage <https://bues.ch/h/crcgen>`_
- `Git repository <https://bues.ch/cgit/crcgen.git>`_
- `Github repository <https://github.com/mbuesch/crcgen>`_
- This tool generates VHDL, Verilog or MyHDL code for use in FPGAs to calculate CRC (Cyclic Redundancy Check) checksums.
- The generated HDL code is synthesizable and combinatorial. That means the calculation runs in one clock cycle on an FPGA.
- Any combination of CRC algorithm parameters and polynomial coefficients can be selected.
- Example usage
- =============
- Display all options:
- .. code:: sh
- crcgen -h
- Generate Verilog code for CRC-32:
- .. code:: sh
- crcgen -a CRC-32 -v
- Generate VHDL code for CRC-32:
- .. code:: sh
- crcgen -a CRC-32 -V
- Generate Verilog code for a custom non-standard CRC or any standard algorithm that's not included in crcgen's -a list:
- .. code:: sh
- crcgen -P "x^8 + x^7 + x^5 + x^4 + x^2 + x + 1" -B16 -R -v
- Online crcgen
- =============
- An easy to use online version of crcgen that can be used without installing or downloading anything to your machine is available here:
