The index of the first output signal in the type array. type can be any of BOOL, INT and REAL.
Each of the arrays (one for each of the basic types boolean, integer and real) is partitioned into input signals, output signals, local signals and state variables. This key provides the index of the first output signal in the array. Hence, the index of the n:th boolean output signal in the boolean array is %OFFSET_BOOLEAN_OUTPUT% + n.
An output signal in the code generation context is an output signal of the top-level node. Outputs of subnodes count as local signals.
