Known Software and Documentation Problems

The Real-Time Workshop 3.0

Rapid Simulation Target

The Rapid Simulation Target is used for accelerating simulations and for batch simulations. Its usage is slightly different from what is documented in the Real-Time Workshop User's Guide.

The Rapid Simulation Target supports all built-in data types for Simulink parameters. The Real-Time Workshop User's Guide incorrectly states that the Rapid Simulation Target only supports block diagrams with double parameters.
You change the values of From Workspace blocks the same way that you change parameters (i.e., use the rsimgetrtp command, save the parameter vector to a .mat file, which will include the From Workspace data, and use the -p switch on the generated executable). Ignore the sections of the manual that discuss using the -w switch.

DSP Processor Support

Real-Time Workshop 3.0 now supports target processors that have only one register size (e.g., 32-bit). This supports data type emulation of 8 and 16 bits on the TCI_C30/C40 DSP and similar processors.

To do this, add -DDSP32=1 to your template makefile and add %assign DSP32=1 to your system target file.

Unsupported Features in Version 3.0

Real-Time Workshop 3.0 does not currently support:

Nonreal-time simulation of variable-step solvers
The Simulink Accelerator

The Fuzzy Logic Toolbox is compatible with the Real-Time Workshop simulation targets only. It is not compatible with hardware targets. The generated fuzzy code is not optimized and will not run on fixed-point embedded microcontrollers (floating-point only). In addition, the generated code may not run on single precision processors such as the Texas Instruments C30/C40 class of DSPs.
