* for debug purpose

* The corrector contains 4 coefficients that are enought to make a
  lag-compensator or lead-compensator
* Change the name of the block to erase "pi"
* Update the simulation data

!! Still error on simulation, to be fixed

* This is handled better by DESYRDL

* Fix delay on matmul valid signal
* Fix length of validity for correction output

All x then all y coefs

* There are always a couple of bits more on the address bus.
* Use a constant for data serializer ram

* Also change the package constant declaration, add a few. All
  mathematic will be done outside of the package.
