Rapid Simulation Target Limitations

The RSim target is subject to the following limitations:

• The RSim target does not support algebraic loops.

• The RSim target does not support MATLAB Fcn blocks.

• The RSim target does not support noninlined M-file, Fortran, or Ada S-functions.

• If an RSim build includes referenced models (by using Model blocks), these models must be set up to use fixed-step solvers for code to be generated for them. The top model, however, can use a variable-step solver as long as all blocks in the referenced models are discrete.

• In certain cases, changing block parameters can result in structural changes to your model that change the model checksum. An example of such a change would be changing the number of delays in a DSP simulation. In such cases, you must regenerate the code for the model.

• Variable-step solver support for RSim is not available on Microsoft^® Windows^® platforms when you use the Watcom C/C++ compiler.
