- When you say multiword, are you looking for an explicit structure/array construct in the generated code that represents a 64-bit number with two 32-bit entries?
- Or are you looking for 64-bit numbers to just be used in the generated code because your compiler is able to accept 64-bit numbers?
- Do you not have access to the Fixed-Point Designer product? Is that why you are trying to avoid the use of fixed-point?
- Stateflow does not support the uint64 and int64 data types, so to use 64-bit numbers in Stateflow, the only option is the double data type for a 64-bit data type, and there is no multi-word for that as best I can tell.
- The Configuration Parameters Hardware Implentation pane is where you start introducing the multiword behavior
- I do not believe any multi-word structures as mentioned above are generated without the Fixed-Point Designer
