DSP Blockset Release Notes |
Known Software Problems
The following sections describe some of the known DSP Blockset problems and limitations:
Real-Time Workshop C Code Generation Limitations
C code generated from DSP Blockset blocks using Real-Time Workshop has the following limitations:
dsp_rt.lib
does not always rebuild when you change compiler or linker options. Thus, before changing compiler and linker options, you should delete dsp_rt.lib
and all associated object files. You can change compiler and linker options in the Simulink Simulation Parameters dialog's Real-Time Workshop tab by setting make
command arguments such as OPTS
or OPT_OPTS
in the Make command parameter (for example, make_rtw OPTS="-DMYDEFINE=1"
).
Nonzero Simulation Start Times Not Supported
The DSP Blockset does not support nonzero simulation start times. When running a simulation with DSP Blockset blocks, you must set the Start time option in the Simulink Simulation Parameters dialog's Solver tab to 0
.
Triggered and Enabled Subsystem Support
Triggered or enabled subsystems currently do not support the following blocks:
|
Digital Filter Design Block Limitations
The Digital Filter Design block has the following limitations:
For details about the Digital Filter Design block, see the previous section, New Digital Filter Design Block.
Magnitude FFT Block Limitations
The Magnitude FFT block currently does not support 2-D sample-based 1-by-N row vector inputs.
