Tips and tricks for using 64 bit integer types in Simulink. Tools and information for easily specifying 64 bit integer types and parameter values in Simulink. Tools include utilities for specifying parameters and a Simulink Library that simplifies modelling with 64 bit integers.

As of R2020a, the tools presented here are no longer necessary. In R2020a or earlier, the Simulink limitations these tools solved were eliminated.

The tools will still work in R2020a, but they are no longer necessary.
If your organization still needs a model to work with R2020a and older releases,
then leave the use of these tools in place.
If your organization has permanently moved to R2020a and later, then you can remove the use of these tools if and when it benefits your work.
