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:

.. 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
