Data Store Rescope Tool

Version 2.6 (1.8 MB) by McSCert
The Data Store Rescope Tool (formerly the Data Store Push-Down Tool) rescopes Simulink data stores.
Updated 22 Jul 2020

Data stores in Simulink are analogous to variables in traditional programming languages. Therefore, they should be restricted in scope to avoid inadvertent/unwanted access, hide low-level details, and reduce the number of inputs for testing. The Data Store Rescope Tool (formerly known as the Data Store Push-Down Tool) identifies the data stores that have scopes larger than necessary. Then, the declaration (Data Store Memory block) of each identified data store is pushed down the model hierarchy to the lowest level possible, such that all the references to the data store memory are still within its scope. Also, if references to a data store are outside of its scope, the Data Store Rescope Tool can be used for auto-correction: the data store’s declaration is first moved to the model's top level, and then pushed-down to minimize data store's scope as previously described.

Fixed several bugs.

Fixed several bugs.

Fixed a big pertaining to the rescoping of Data Store Memory blocks into the top-level of the model.

– The tool now offers the option of pushing down to linked subsystems
Changed the cover image and made minor changes to the description.
Formatted description text.

– Added scope repair transformation when data store's references are outside its scope
– Now properly handles cases where multiple Data Store Memory blocks exist with the same name and overlapping scopes
- Robustness, user guide improved

Made a change to Required Products (a tool was previously listed by mistake).
