* A simple threhshold comparator on data output.
* When Thresh is reached, disable correction (keep value).
* User can unlock the situation via control bits.
* Same threshold for all pscid.

* 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

*  Instead of deriving ID field width

* Tie version register
* Import lib
* Copy data input before simulation

* 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.
