## Introduction

Fully parametrizable combinatorial parallel LFSR/CRC module.  Implements an unrolled LFSR next state computation.  Includes full cocotb testbenches.

## Documentation

### lfsr_crc module

Wrapper for lfsr module for standard CRC computation.

### lfsr_descramble module

Wrapper for lfsr module for self-synchronizing descrambler.

### lfsr_prbs_check module

Wrapper for lfsr module for standard PRBS check.

### lfsr_prbs_gen module

Wrapper for lfsr module for standard PRBS computation.

### lfsr_scramble module

## Testing

Running the included testbenches requires [cocotb](https://github.com/cocotb/cocotb) and [Icarus Verilog](http://iverilog.icarus.com/).  The testbenches can be run with pytest directly (requires [cocotb-test](https://github.com/themperek/cocotb-test)), pytest via tox, or via cocotb makefiles.
