- sim
A list containing two elements. The first element is
a string containing the name of the computational function
(C, Fortran,or Scilab). The second element is an integer
specifying the type of the computational function. Currently
type 4 and 5 are used, but older types continue to work to
ensure backward compatibility.
For some older case, sim can be a single string and that
means that the type is supposed to be 0.

- blocktype
Character that can be set to 'c' or 'd'
indifferently for standard blocks. 'x' is used
if we want to force the computational function to

the block does not contribute to computation of
the state derivative.
'l', 'm' and 's' are reserved. Not to be used.

- dep_ut
Boolean vector [dep_u, dep_t].
- dep_u
true if block is always active.
(output depends continuously of the time)
- dep_t
true if block has direct feed-through,
i.e., at least one of the outputs depends
directly (not through the states) on one
of the inputs.
In other words, when the computational
function is called with flag 1, the value
of an input is used to compute the output.

- nmode
Length of the mode register. Note that this gives the size of
the vector mode and not the total number of modes
in which a block can operate in. Suppose a block
has 3 modes and each mode can take two values, then
the block can have up to 2^3=8 modes.
Size : Number of modes.
Type : column vector of integer numbers.
- equations
Used in case of implicit blocks.
Data structure of type modelica which contains modelica
code description if any. That list contains four entries :
- model
a string given the name of the file that contains
the modelica function.
- inputs
a colunm vector of strings that contains the names of
the modelica variables used as inputs.
- outputs
a colunm vector of strings that contains the names of
the modelica variables used as outputs.
- parameters
a list with two entries. The first is a vector of strings
for the name of modelica variable names used as parameters
and the second entries is a list that contains the value of
parameters.
Names of modelica states can also be informed with
parameters. In that case a third entry is used to do the
difference between parameters and states.
For i,e :
mo.parameters=list(['C','v'],list(C,v),[0,1])
means that 'C' is a parameter(0) of value C, and 'v'
is a state(1) with initial value v.
