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.

The size can be negative, equal to zero or positive :
If a size is less than zero, the compiler will try to find the appropriate size.
If a size is equal to zero, the compiler will affect this dimension by added all positive size found in that vector
If a size is greater than zero, then the size is explicitly given.

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 be called during the simulation phase even if the block does not contribute to computation of the state derivative.
'l', 'm' and 's' are reserved. Not to be used.

firing
Vector of initial event firing times of size equal to the number of activation output ports (see evout). It contains output initial event dates (Events generated before any input event arises). Negative values stands for no initial event on the corresponding port.

dep_ut
Boolean vector [dep_u, dep_t] where values are :
dep_t%tif block is always active. Output depends continuously of the time.For instance, the GENSIN_f block computes
y=sin(t)sodep_ut=[%f %t].dep_u%tif 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 flag1, the value of an input is used to compute the output.For instance, the SUM_f block computes
y=u1+u2sodep_ut=[%t %f].

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, inputs, outputs and parameters.
model
a string given the name of the file that contains the modelica function.
inputs
a column vector of strings that contains the names of the modelica variables used as inputs.
outputs
a column 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.

Type : scilab list.
uid
Unique identifier string of the block (2^16 per host)
This identifier will be only set using the Xcos GUI. To set a specific value at bloc allocation, use the following code:
jimport("java.rmi.server.UID"); juid = jnewInstance("java.rmi.server.UID"); uid = juid.toString()
Size : 1x1.
Type : String.
