i_seed is the starting value for the LFSR, the seed

Any other tips for using this for a CRC?
Also can you please share the tb.

Cheers,
Joe

yes, if the zero is a singularity for the LSFR, I mean the it gets stuck

Is it normal ?

w_mask implement the generator polynomial

And the purpose of the AND with r_lfsr(1). I understand the polynomial but not why we create w_mask by anding with only the last value in r_lfsr
