Generator for CRC HDL code

This code generator creates HDL code (Verilog) for any CRC algorithm.
The HDL code is synthesizable and combinatorial. That means the calculation runs in one clock cycle on an FPGA.

Please select the CRC parameters and the output language settings below.
Then press "generate" to generate the code.

Select CRC algorithm:
Bits:
Polynomial:

Select output language:

Algorithm optimization:

Names:
Function/module:
Data parameter:
CRC input parameter:
CRC output parameter:
