A driver or library has two associated data files:

Data Definition File (MDD or MLD file)
This file defines the configurable parameters for the driver, OS, or library.
Data Generation File (Tcl)
This file uses the parameters configured in the MSS file for a driver, OS, or library to generate data. Data generated includes but is not limited to generation of header files, C files, running DRCs for the driver, OS, or library, and generating executables.

The Tcl file includes procedures that tool calls at various stages of its execution. Various procedures in a Tcl file include:

DRC
The name of DRC given in the MDD or MLD file.
generate
A tool-defined procedure that is called after files are copied.
post_generate
A tool-defined procedure that is called after generate has been called on all drivers, OSs, and libraries.
execs_generate
A tool-defined procedure that is called after the BSPs, libraries, and drivers have been generated.
Note: The data generation (Tcl) file is not necessary for a driver, OS, or library.

For more information about the Tcl procedures and MDD/MLD related parameters, refer to Microprocessor Driver Definition (MDD) and Microprocessor Library Definition (MLD).
