Wasn't the encoder a shift register, an xor and a D-FF?

A LUT is one approach as well.

Would be another chance to create a component.

I forgot to mention, for a given application, Verilog the optimal

   

approach, in a specific fabric and application. Of course Verilog

   

has to be up to snuff.

Hi

   

Thanx Bob and is the .jpg file you sent a part of a project that can be useful for me to look at. If so, is it possible to get to look at the whole project. Can you upload it. I'm also working on the decoding and will post it too.

   

Regards

I'm sorry, that picture I created just on-the-fly with my limited knowledge of NRZI. No Project, no component (yet).
