CRC algorithm code generator

Project description

CRC algorithm code generator

This tool generates synthesizable Verilog, VHDL or MyHDL code for use in FPGAs to calculate CRC (Cyclic Redundancy Check) checksums.

Example usage

Display all options:

crcgen -h

Generate Verilog code for CRC-32:

crcgen -a CRC-32 -v

Generate VHDL code for CRC-32:

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:

crcgen -P "x^8 + x^7 + x^5 + x^4 + x^2 + x + 1" -B16 -R -v
