Current Status

• This module mainly build for learning purpose. Some bugs might exist but should not affect functional simulation. (and yes, please report them if you find ones).

  • viterbi_testbench.v
• Main Modules :
  • viterbi.v
    Top Level Module for VDK3R1/2.
  • viterbi_distances.v
    This module is used to find the hamming distance of received input to all branch output.
  • compute_metric.v
    This module is used to accumulate the error metric.
  • compare_select.v
    This module is used to find the smaller accumulated error metric entering a state.
  • reduce.v
    This module is used to limit the size of error metric.
  • metric.v
    This module is used as memory for the accumulated error metric.
  • path_memory.v
    This module saves the survival predecessor state to survivor memory and doing traceback process to determine output bit.
• Additional Modules :
  • acs_enable.v
  • back.v
  • dff.v
