Currently a Simulink and Stateflow front-end and a C-language back-end are included. |
- | + | Some of the strengths of UCGN: | |
+ | * Clearly readable source-code | ||
+ | * Separation of functionality and parameters ("tunable parameters") | ||
+ | * Robust data storage (compile-time static structures in favor of pointer run-time constructs) | ||
+ | * Clear software architecture, direct correspondence to the model architecture | ||
+ | * Separation of reusable library code | ||
+ | * Simplicity and uniformity of software interfaces (for testing etc.) | ||
+ | The following features are supported by the Simulink/UCGN | ||
+ | * Discrete single-rate Simulink models and libraries | ||
+ | * Block library with 50+ standard Simulink blocks | ||
+ | * Periodic, condition-driven Stateflow charts (including flowgraphs, loops) | ||
+ | * Structured data types through bus objects | ||
+ | * Simulink native enumerations | ||

+ | |||
+ | June 28, 2010: Released SimulinkUcgnDistribution_1.0.2.zip, fixing two bugs (expression precedence and array copy indexing) | ||
+ | |||
+ | July 7, 2010: Released 1.0.3 which contains some minor bug fixes and robustness additions. Also, environment variables (with the syntax %VAR%) can now be used in the working directory property of the project xml files. | ||
+ | |||
+ | February 1, 2011: Released 1.0.4, enabling the use of Simulink enumerated types in Simulink and Stateflow models. This release also contains several bug fixes. | ||
+ | |||
+ | February 17, 2011: Released 1.1.0, the use of flowgraph loops in Stateflow is now enabled. | ||
+ | |||
+ | May 27, 2011: Released 1.1.1, bundling some smaller bugfixes. | ||
+ | |||
+ | August 30, 2011: Released 1.1.2, just some smaller bugfixes | ||
+ | |||
+ | March 29, 2012: Released 1.1.3, bugfixes and stability; also, updated to Simulink's new way of handling of Lookup/Interpolation, added sizeof operation to Stateflow | ||
