* Trying to simulate the StopToCurrent going to mean value
* Simulation time is very very long... probably not a good idea

* Correction output is integrated and dumped every 1024 values
* when corrector is disabled, switch output to averaged value

* Also I had a nasty GHDL error that was solved by this, not sure why...

* align memory access
* adapt to new rounding in filter

* add round of 8 bits on mult A
* Add a pipeline stage

* increase coeff +2 bits
* add saturation and proper rounding on result (sat 7 bits, round
  15 bits)
* In scale with Libera implementation of MatMult

* Add constant for number of BPM
* Change the register addresses

* Not sure, but maybe there was a sign issue there

* for debug purpose

* Allow ID up to 255
* This changes dimension of memories, registers

* X and Y corrector controls are split
* Signed representation of coefficients

* The memory length depends on the serializer counter

* Matrix lines are numbered from 0 to 99
* X from 0 to 49 included, Y from 50 to 99 included

* Use DESYRDL specific property

* Two different register for enable and reset
* Duplicate coeffs
* Based on PSCID **table index**. > 50 is Y

* Threshold autostop is kept on both plane.
  Control moved to a dedicated register.
  When reached, stop both planes.

feat(average): Add orbit error and correction command moving average

fix(sim): Fiw simulation to match two correctors, add traces for moving
average

* Cast to signed

* No auto check !

* Update register address
* Configure second register as unitary

* Same generic bloc for operations
* Capture the stream of data and retains accumulator in memory
* Mirror memory for CPU readout

wip: initial commit

wip: Now a more generic bloc

wip: Add average tables to RDL

wip: integrate ma for oe in toplevel

wip: first corrections for simulation, alpha declared in package

wip: fixes for simulation

wip: fixes, secondary memory is smaller, no decimal part

wip: true rounding before wrinting to secondary memory

wip: Add average for PSC command

wip: fix sign extension on average orbit read

* Effective number of bit did not get over, but it is better to protect.

* typo: Enable bit also drove reset...
* use a NOR rather than a OR -> real thresh

* 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.

*  Allows second order correction

* Add SUMSAT saturation
* Add first iteration with 0 in registers

* 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

* PSCID memory read require one clock tick, so add a pipeline stage
* To limit complexity, remove tready. Throttling will be done outside

* Change address with the new layout
* Add PSCID filling and checking

* This reads the memory in the proper order.

* This is handled better by DESYRDL

*  Instead of deriving ID field width
