common Cyclic Redundancy Check standards are CRC-8, CRC-12, CRC-16, CRC-32, and CRC-CCIT. This application note discusses the implementation of an IEEE 802.3 CRC in a Virtex device. The reference design provided with this application note provides Verilog point solutions for CRC-8, CRC-12, CRC-16, and CRC-32. The Perl script (crcgen.pl) used to generate this code is also included. The script generates Verilog source for CRC circuitry of any width (8, 12, 16, 32), any polynomial
