* there are 7 simulation files .asc :

  - frequency sweep : showing the impedance for a sweep of frequency for a series of capacitors values
  - 4 x DC voltage sweep :
  - temperature sweep  : in these files, the simulation results are visualized by opening the LTspice error log file
    "view" in principal menu, then right click "plot stepped meas. data"
    these simulations show the ratio variations Capacitance/C(Temp=25 C) or Capacitance/C(Voltage =0V) in function of the temperature and DC voltage.
  - leakage current :showing the increase of leakage current for a sweep of the DC voltage.

* tolerances according to Monte Carlo : the tolerances on capacitance value at 25 C are parameters named tolCmin (negative) and tolCmax (positive).
  The values of these parameters are fixed by the specifications.They can be changed by the user though

   examples:
   ========
   In component attribute editor, fill value 2 as follows. (empty) means left completely blank.

   example 1
   =========
   value 1  VY1100K31U2J
   value 2   (empty)                 : tolerances are fixed by the library at +/-10 %

   example 2
   =========
   value 1  AY2152M31Y5U
   value 2  (empty)                  : tolerances are fixed by the library at +/-20 %

   example 3
   =========
   value 1    VY2472M49Y5U
   value 2    tolCmin=-20 tolCmax=-20   : the value is defined at -20%

   example 4
   =========
   value 1    VY2472M49Y5U
   value 2    tolCmin=-20 tolCmax=-20   : the value is defined at -20%

  example 5
  =========
   value 1    VY2472M49Y5U
   value 2    tolCmin=0 tolCmax=0   : the value is defined at nominal
