3.4 Configuring ARMulator to use a new model
ARMulator determines which models to use by reading the .ami and .dsc configuration
files. See ARMulator configuration files on page 4-63.
Before a new model can be used by ARMulator, you must add a
.dsc file for your model,
and references to it must be added to the configuration files
default.ami and
peripherals.ami .
The procedures are described in the following subsections:
• Adding a .dsc file
• Editing default.ami and peripherals.ami on page 3-9.
3.4.1 Adding a .dsc file
Create a file called
MyModel.dsc and place it in install_directory\Bin . It must contain
the following:
;; ARMulator configuration file type 3
{ Peripherals
{MyModel
MODEL_DLLfilename=MyModel
}
{
No_MyModel=Nothing
}
}
where the name of your model is one of:
•
MyModel.dll
• MyModel.so
• MyModel.sl
Nothing
is a predefined model that does nothing. The No_MyModel=Nothing line allows the
use of
No_MyModel in a .ami file. This allows a user to configure ARMulator to exclude
your model (see Configuring ARMulator to disable a model on page 3-10).
You can include other configuration details in your
MyModel.dsc file if required. See the
supplied
.dsc files in install_directory\Bin for examples.
