How do I initialize buses in Simulink?

I have a model containing a Bus Creator block. The bus is then used in a conditionally executed subsystem. Initialization of Simulink buses is needed, in cases where a Simulink bus is the output of conditionally executed subsystems or unit delay blocks.

The ability to initialize buses is not available in Simulink. Only Simulink buses of the same datatype may be initialized using the following workaround.

To work around this issue, in the output port of the subsystem a vector of the correct number of bus elements may be specified for the "Initial Output" parameter: [1 1 1 1]. This vector can be used regardless of the hierarchical breakdown of the bus.
