-- 2016/05/22   v0.01.0010  [JD]    started development. design of blocks and port interfaces.
-- 2016/06/05   v0.01.0090  [JD]    all modules integrated. testbench for basic test vectors verification.
-- 2016/06/05   v0.01.0095  [JD]    verification failed. misalignment of words in the datapath. 
-- 2016/06/06   v0.01.0100  [JD]    first simulation verification against NIST-FIPS-180-4 test vectors passed.
