DSP Builder Release Notes
Update the MegaCore Functions in your Design
After you have upgraded designs containing MegaCores functions, the
MegaCore blocks should be regenerated to ensure they are up-to-date.
This can be done either by individually double-clicking on each block,
(changing the parameters, if required) and clicking the Generate option,
or by entering the following command at the MATLAB prompt:
alt_dspbuilder_refresh_megacore
This command automatically regenerates all the MegaCore functions in
the upgraded design, using the existing parameterizations.
Non-synthesizable Simulink components
In pre-v7.1 releases, it was possible to connect non-synthesizable blocks
within a DSP builder system which would be automatically ignored by
Signal Compiler. For example, a design may have included Simulink
assertion blocks that halted the simulation if the output on a particular
pin changed. It is now not possible to connect to blocks that accept
doubles only; therefore it may be necessary to add non-synthesizable
output blocks before such blocks.
Using a Simulink Library Forwarding Table
You can use a Simulink library forwarding table to update models with
changes in the names or locations of the library blocks that they reference.
Using this feature, all of the links in the upgraded version of the old file
can be quickly and easily changed to point to a different library.
f For more information, refer to Making Backward-Compatible Changes to
Libraries in the MATLAB Simulink help.
