When the timing analysis has been performed and the feasibility of the individual subnetworks
has been established LDF files will automatically be created for each network (Figure .).
Textual reports can be generated as well, to enhance the readability of information for all parties
involved in the design, verification, and maintenance process.
17.12 LIN Target Package
The LTP represents the embedded software portion of the Volcano tool chain for LIN. The LTP is
distributed as a precompiled and fully validated object library also including associated documen-
tation and a command line configuration utility (LCFG) with automatic code generation capability,
generating the configuration specific code and set of data structures.
ImplementingtheLTPwithanapplicationprogramisasimpleprocess.heLDFcreatedbythe
off-line tool contains the communication-related network information. In addition a Target File as
an ASCII-based script defines low-level microcontroller information such as memory model, clock,
SCI, and other node specifics to the LTP. hese two files are run as input through the command line
utility LCFG. It converts them both into target-dependant code usable by the microcontroller. The
output contains all relevant configuration information formatted into compiler-ready C source code
(Figure .).
The target-dependent source code is added to the module build system along with the precompiled
object library. Ater compilation the LTP gets linked to the application functionality to form the target
image which is ready for download.
