Appendix B: LMTV Command Reference
$lm_load_file() or $lai_load_file()
Use these commands to load the memory contents of the file filename into the instance
inst_path, which can be either a programmable device or a memory model. Using these
commands eliminates the write cycles required to set up the contents of the model.
The load_file operation causes the selected model to reset its internal state to simulation
startup conditions and then read the specified file. After the file is read, the model is
evaluated as a function of the new internal state and the current inputs and outputs are
scheduled with zero delay. After this initial evaluation phase, the model behaves as it
would normally.
You can load a model with any file type that would normally be accepted by the model
at initialization. Additionally, the new configuration file you load is used for the
specified model instance after any subsequent command to reset or reinitialize.
Syntax
$lm_load_file ( inst_path [, “filename”, “file_type”] );
$lai_load_file ( inst_path [, “filename”, “file_type”] );
Arguments
inst_path
The path name to the SmartModel instance into which
the contents of filename is to be loaded.
filename
The path name to the configuration file that is to be
loaded for the model instance specified by inst_path.
The default is to use a path name defined with the
defparam statement in the design.
file_type
The type of file to be loaded. Allowed values are
MEMORY, JEDEC, PCL, and SCF. The default is to
use the file type of the file defined with the defparam
