Fixed-Point Blockset Release Notes

Installation and Licensing

To support the sharing of models in a large organization, Version 4.0 of the Fixed-Point Blockset is automatically installed whenever Simulink is installed. You can configure models to either take full advantage of all fixed-point features, or to run without a Fixed-Point Blockset license. Therefore all Simulink users in your organization can run and work on the same model, regardless of whether they have a Fixed-Point Blockset license.

You must have a Fixed-Point Blockset license to run a model if it is configured to log minimums, maximums, or overflows. You control logging with the system-level setting Logging mode. If you turn logging off at the top-level system in a model, then no data is logged for any block in any subsystem of the model, and a Fixed-Point Blockset license is not required. You also need a Fixed-Point Blockset license to run a model that uses any nonbuilt-in, fixed-point data types. However, you can use the system-level setting Data type override to force blocks to use doubles or singles instead of fixed-point data types. Therefore, by turning the Data type override parameter on and the Logging mode parameter off at the top level of a model, a Simulink user without a Fixed-Point Blockset license can run a model with fixed-point enabled blocks. See Global Data Type Override and Logging Modes for more information on these settings.

If you have a Fixed-Point Blockset license, you can run bit-true simulations with your models that contain fixed-point enabled blocks. If a Fixed-Point Blockset license is not available or desired, you can turn logging off and data type override on at the top level of your model and perform idealized floating point-based simulations.

If you have both a Fixed-Point Blockset license and a Real-Time Workshop license, you can generate bit-true integer code from your models with fixed-point enabled blocks. If you do not have a Fixed-Point Blockset license but you do have a Real-Time Workshop license, you can generate idealized floating-point code from your models with fixed-point enabled blocks.
