Altera Corporation Software Version 7.1 SP1 9
DSP Builder Release Notes
Upgrading Your Existing Models
4. Enter the following command at the MATLAB prompt:
alt_upgradeModel <model name> option1 option2 ...
Any number of the available options can be used in any order.
Table 2 describes the available options.
5. Save your design and close it (including any libraries that may have
changed).
The design is reloaded and all libraries are correctly initialized when
it is reopened.
A copy of the model is backed up to a backup subdirectory and all
blocks in the model updated to use the new v7.1 Altera DSP Builder
Blockset. If a backup subdirectory already exists, a new subdirectory
is created by appending an integer (for example backup1).
1 You cannot revert a design model to a previous version after you
have updated it to v7.1. If you want to use an older version of
DSP Builder, you should use the version saved in the backup
subdirectory.
Limitations of the Upgrade Model Utility
The blocks in your model are upgraded to use the corresponding block in
the new v7.1 blockset. However some blocks may be obsolete or require
manual intervention to complete the conversion process.
Table 1. Options to the altUpgradeModel Command
Option Description
UnlockLibraries Causes libraries to be recursively unlocked and modified if referenced from
the upgraded design. Already-unlocked libraries are always upgraded.
RemoveSubsystemAltBusBlocks Upgrades the model and also deletes any unnecessary AltBus input blocks
connected to subsystem inputs and AltBus blocks connected to subsystem
outputs. In general, it is no longer necessary to have AltBus blocks connected
to every subsystem input or output and removing them means that bit widths
can be propagated into subsystems. However, the bit width specified on an
AltBus block may be used to reshape the inputs and outputs from the system
and removing these blocks may cause the behavior to change and in some
cases may cause unresolvable propagation loops.
Verbose Displays information about each block as it is upgraded or removed.
