Known Software Problems

•When you install the Filter Design Toolbox, FDATool, opened from the
MATLAB command line, gets a new tab,
Set Quantization Parameters.
However, the Digital Filter Design block’s FDATool does not currently
support the
Set Quantization Parameters tab.
•The Digital Filter Design block currently allows you to edit nontunable
FDATool filter specification parameters. When you edit nontunable
parameters during a simulation, the filter still updates in FDATool to reflect
your changes. However, during simulation, FDATool only updates the block
icon (which displays the frequency response of the updated filter). FDATool
sends the new filter coefficients to the block only after the simulation stops
running.
For details about the Digital Filter Design block, see the previous section, “New
Digital Filter Design Block” on page 13-2.
Magnitude FFT Block Limitations
The Magnitude FFT block currently does not support 2-D sample-based 1-by-N
row vector inputs.
